Abstract

A screw driving machine includes a driving piston to which a driver bit is attachable, a driving cylinder partitioned into a first chamber and a second chamber by the driving piston and moving the driver bit when compressed air is supplied to the second chamber, an air motor rotating the driver bit by the compressed air, an air flow path communicating the second chamber and the air motor, a main chamber storing the compressed air and communicating with the air flow path, and a main valve opening and closing communication between the air flow path and the main chamber. The driving cylinder has a supply port communicating the air flow path and the second chamber. A throttle portion is disposed to be displaceable on an outer periphery of the driving cylinder to change an opening area of the supply port.
