装置。[Claim for Utility Model Registration] The reciprocating motion of the piston in the cylinder generates air pressure fluctuations in the air chamber provided between the striking element and the piston, driving the striking element back and forth, and striking the tip tool via the intermediate. In the impact tool, a part of the inner periphery of the hammer holder that holds the intermediate element is formed into a conical shape, and inside the hammer holder is a cylinder whose end surface is biased toward the impactor side by a spring so as to be movable in the tool axis direction. A number of loosely inserted balls (the balls do not come out of the cylinder) are held in the cylinder, and the balls are pressed against the conical surface of the hammer holder by the spring. Further, the impact tool idling prevention device is configured to be inserted into the hammer holder when the tip of the impactor moves forward in the impact tool idling chamber.
