Abstract

A pneumatic tool includes a drive part configured to be driven by compressed air, a control valve configured to switch the presence or absence of operation of the drive part, and a timer part configured to switch the presence or absence of operation of the control valve after a lapse of a predetermined time. The timer part includes a timer piston configured to move in one direction, a timer piston cylinder configured to support the timer piston such that the timer piston can slide, and an on-off valve part configured to switch the presence or absence of operation of the control valve in conjunction with the timer piston. The on-off valve part includes a shaft portion configured to move in conjunction with the timer piston, and compressed air flowing into the on-off valve part presses the shaft portion in the one direction.
