A main valvein a ring shape is arranged along an outer periphery of the strike cylinderon an upper side of a ring-shaped flange portion. An outer peripheral edge portionof a piston stopof rubber or the like arranged on an upper side of the strike cylinderis arranged to extend in a lower direction from an upper end portion along an outer peripheral face of the strike cylinderto thereby form an air exhaust valve seatat a lower end of the outer peripheral edge portion. In addition, an air intake/exhaust pathfor guiding compressed air from the main valveto an upper end edge of the strike cylinderis formed between an outer peripheral face of the cylinder sealand an inner peripheral face of the outer peripheral edge portionof the piston stop
