工具のバンパ。 This bumper is installed at the lower end side of the impact cylinder disposed in the impact tool body, and receives the impact piston, which is slidably and tightly fitted into the impact cylinder, at the bottom dead center position. A driver insertion hole is formed at an eccentric position with respect to the central part of the bumper so as to correspond to the impact driver installed at an eccentric position, and an escape hole is formed continuous with this driver insertion hole, so that the driver can be mounted at an eccentric position. A bumper for an impact tool, characterized in that the thickness of a collision surface, which is a flat surface between an insertion hole, an escape hole, and an outer periphery of the bumper, is made substantially uniform over the entire circumference.
