A hollow fiber membrane module 10 including an outer case 100, an inner case 200, a hollow fiber membrane bundle 300 having a plurality of hollow fiber membranes filled in an annular gap between the outer case 100 and the inner case 200, a first sealing part 410, and a second sealing part 420, the hollow fiber membrane module 10 further including a membrane exterior passage that is formed to pass from an opening of the inner case 200 through a first through hole 230 and reach a second through hole 130 through the exteriors of the plurality of hollow fiber membranes, and a membrane interior passage that is formed to pass through the interiors of the plurality of hollow fiber membranes, wherein, a cylindrical member 500 having a plurality of third through holes 510, each of which becomes a part of the membrane exterior passage, is provided between the hollow fiber membrane bundle 300 and the outer case 100.

Provided is a gasket having high conformability to an object being contacted and having excellent pressure resistance and heat resistance. A gasket 1 is provided with: a plurality of flow path portions 10 each being a tubular member and having a pair of openings 11, 12; and a base body 20 having a pair of surfaces, namely, a front surface 21 and a rear surface 22 facing away from each other. The base body 20 is elastic. The flow path portions 10 are held by the base body 20 in such a manner that the openings 11, 12 respectively open on the front surface 21 and the rear surface 22 of the base body 20, so as to form a flow path for a sealing target object. Hardness of the base body 20 is lower than hardness of the flow path portions 10.

A pipe connector (11) connecting two pipes is mainly configured of a cylindrical elastic body (21) made of rubber, and includes connection portions (22A, 22B) respectively fitted to the two pipes being provided at both ends of the pipe connector, and a diaphragm (23) being provided in a central portion thereof. A first reinforcing ring (31) is embedded in one connection portion (22A), and a second reinforcing ring (41) is embedded in the other connection portion (22B). The first reinforcing ring (31) has a first cylinder (32) and a first flange (33), and the second reinforcing ring (41) has a second cylinder (42) and a second flange (43). The first flange (33) receives the force of a jig in a direction from the other connection portion (22B) toward the one connection portion (22A), and the second flange (43) receives, on the outer periphery of the elastic body (21), the force of a jig in a direction from the one connection portion (22A) toward the other connection portion (22B).

Provided is a sealing structure capable of preventing a portion of a gasket from being lifted up from a fitting groove when the gasket is fitted into the fitting groove. A gasket 300 includes an annular gasket main body 310 to be fitted into a fitting groove 210 and a plurality of protrusions 320 provided on an inner circumferential surface of the gasket main body 310, the protrusions 320 being provided spaced apart from each other in a circumferential direction. In a state where the gasket 300 is fitted in the fitting groove 210 before a first member and a second member are fixed together, the protrusions 320 are in contact with one of sidewalls of the fitting groove 210, and the gasket main body 310 has a meandering portion 312 which is not in contact with either of the sidewalls of the fitting groove 210.

An electrically conductive structure that enables saving of space and, in a use state, reducing a decrease in electrically conductive performance is provided. An electrically conductive structure (1) includes: a holding member (2) that is an annular member with electrical conductivity around an axis x; and an electrically conductive member (3) that is an annular member around the axis (x). The electrically conductive member (3) has at least one gap (10) formed to extend in a radial direction and includes at least one electrical conductor (20) with electrical conductivity extending around the axis x. The electrically conductive member (3) is held by the holding member (2). The electrical conductor (20) has a pair of ends (20a, 20b) in a direction around the axis x. The gap (10) is continuous with the ends (20a, 20b) of the electrical conductor (20).

A sealing device (1) includes: a reinforcement ring (10); and an elastic body portion (20) that has a seal lip (21), is mounted on the reinforcement ring (10), and is formed with an elastic body. An atmosphere-side surface (23) of a lip distal end portion (22) of the seal lip (21) has an inhibition portion (30) which inhibits leakage of a sealed fluid to an atmosphere side (a) in forward rotation of a rotating shaft and has a storage portion (40) which stores the sealed fluid which leaks out to the atmosphere side (a) in reverse rotation of the rotating shaft (50). The inhibition portion (30) has a plurality of screw projections (31) for returning the sealed fluid, which leaks out, to a sealing target object side (b) by a pump action when the rotating shaft performs the forward rotation. The storage portion (40) has a weir portion (41) for blocking the sealed fluid, which leaks out to the atmosphere side (a), when the rotating shaft performs the reverse rotation.
