たことを特徴とする空打ち防止装置。 In a striking tool that has a striking element driven by air pressure caused by the reciprocating motion of a piston, an intermediate element that transmits the striking force from the striking element to the tool, and a damper and ring that dampen the reaction force after the intermediate element strikes the tool, elasticity is applied in the radial direction. A dry firing prevention device characterized in that a stepped portion is provided at the forward position of a force receiving ring and an intermediate piece sliding on the inner periphery of the ring to reduce the rebound speed of the intermediate piece after being struck by a tool.
