A driving tool includes: a nose portion having an injection passage of a fastener; a drive mechanism configured to drive the fastener supplied to the injection passage; a trigger portion configured to actuate the drive mechanism; a movable member that is provided movably to take a first position where an operation of the trigger portion is enabled, and a second position where the operation of the trigger portion is disabled; and a contact arm that is configured to move by being pressed against a workpiece. The contact arm includes a first arm engageable with the movable member, a second arm that is configured to abut against the workpiece, and a rotating portion. The second arm is configured to be movable relative to the first arm by rotating the rotating portion. Rotation of the rotating portion is restricted by a magnetic force.

A driving tool includes: a main chamber configured to store compressed air; a striking cylinder configured to move a striking piston in an axial direction along an up-down direction by being supplied with the compressed air from the main chamber; and a main valve portion configured to switch between supplying and not supplying the compressed air to the striking cylinder. The main valve portion includes: a head valve configured to open and close communication between the striking cylinder and the main chamber; and a control chamber configured to control opening and closing of the head valve by intake and exhaust of the compressed air supplied from the main chamber. The control chamber is provided on an outer periphery of the head valve.

A driving tool includes: a main chamber storing compressed air; a striking cylinder configured to move a striking piston in an axial direction by being supplied with the compressed air from the main chamber; and a main valve portion switching between supplying and not supplying the compressed air to the striking cylinder. The main valve portion includes: a head valve opening and closing communication between the striking cylinder and the main chamber; a main valve biasing portion configured to bias the head valve in a closing direction or an opening direction; and a control chamber configured to control opening and closing of the head valve by intake and exhaust of the compressed air supplied from the main chamber. The main valve biasing portion is provided outside the control chamber.

A nail driving machine includes: a magazine configured to accommodate connected nails in which a plurality of nails are connected; and a nose portion having an injection passage of the nails. A feed path configured to guide the connected nails from the magazine to the injection passage is provided. The magazine includes a magazine main body capable of accommodating the connected nails, and a magazine cap portion attached to the magazine main body to be openable and closable. At least a part of the feed path is formed by a noseside guide surface of the nose portion and a magazine cap-side guide surface of the magazine cap portion.

A driving tool includes a main body, a main chamber storing compressed air, a striking cylinder moving a striking piston in an axial direction, a main valve portion configured to control supply of the compressed air to the striking cylinder, a trigger valve portion actuating the main valve portion, a trigger portion actuating the trigger valve portion, and a contact portion movable in a driving direction of the striking piston. The contact portion includes a contact top to be pressed against a driven member and a contact arm. The trigger valve portion includes a pilot valve and a trigger valve stem. The trigger portion includes a trigger lever and a contact lever portion engageable with the contact arm and the trigger valve stem. A restricting portion in the main body restricts movement of the contact lever portion.

A driving tool includes: a main chamber configured to store compressed air; a striking cylinder configured to move a striking piston in an axial direction along an up-down direction by being supplied with the compressed air stored in the main chamber; a main valve portion configured to open and close communication between the striking cylinder and the main chamber; a trigger valve portion configured to cause the main valve portion to operate; and a first stem configured to be actuated in response to an operation. The trigger valve portion includes a pilot valve configured to cause the main valve portion to operate, and a second stem configured to control intake and exhaust of the compressed air to switch whether the pilot valve operates. The first stem causes the second stem to operate.

A long medium has a start end, a final end, a first side edge connecting the start end and the final end, and a second side edge connecting the start end and the final end. The long medium includes first reference holes formed at a first pitch along the first side edge, N pieces of first conveyance holes formed along the first side edge at a second pitch smaller than the first pitch, and formed between adjacent first reference holes, in which N is a positive integer, first index holes formed along the first side edge at a third pitch smaller than the first pitch and respectively positioned in first index hole forming areas each set between the adjacent first reference holes, and second reference holes formed at the first pitch along the second side edge.

It provides a reinforcing bar binding machine that allows binding objects such as reinforcing bars to be bound by wires with end portions of the wires directed to the binding object side. The reinforcing bar binding machine (1A) includes: a magazine (2A) in which two wires (W) are housed in a drawable manner; a curl guide unit (5A) that winds the juxtaposed wires (W) around the reinforcing bars (S); a wire feeding unit (3A) that winds the wires (W) around the reinforcing bars (S) with the curl guide unit (5A) in an operation of juxtaposing and feeding the wires (W) and winds the wires (W), which is wound around the reinforcing bars (S), around the reinforcing bars (S); and a binding unit (7A) that twists crossing portions of one end side and the other end side of each of the wires (W) wound around the reinforcing bars (S). The binding unit (7A) includes a bending portion (71) that bends the one end side and the other end side of each of the wires (W), which are wound around the reinforcing bars (S), toward the reinforcing bars (S).

A refill includes: a bottom wall; a first side wall; a second side wall; and a front wall in which a discharge opening is formed. The first side wall includes, in a part thereof in a stacking direction, a first inclined wall extending in a coupling direction of staples and inclined in an axial direction. The second side wall includes, in a part thereof in the stacking direction, a second inclined wall extending in the coupling direction of the staples and inclined in the axial direction. The first inclined wall and the second inclined wall are inclined in the same direction, and at least a part of the first inclined wall and at least a part of the second inclined wall are formed at the same height from a bottom surface of the bottom wall in the stacking direction.
