具の衝撃力緩和装置。 In a striking tool that has a striking element driven by the reciprocating motion of a piston and air pressure and that applies a blow to the tool via the intermediate element, the intermediate element is provided with a stepped portion,
A shock absorbing material made of an elastic material is provided at a position corresponding to the intermediate stepped portion of the front cover that guides and holds the tool and the intermediate, so as to have a sealing property between the intermediate and the intermediate, and air pressure is generated between the intermediate and the front cover. An impact force mitigation device for a striking tool, which is configured to absorb impact force when an intermediate member is locked to a machine body by a front cover at the most advanced position, and to reduce the impact force on the machine body.
