を、その外周に設けた凹部3aと上記ストッパーボール
が係嵌して前進限に停止するよう構成したことを特徴と
したハンマードリル等の空打防止機構。This is a dry striking prevention mechanism for hammer drills, etc., in which a hammer 3 is reciprocated by compressed air from a piston 1 to generate a striking force on a tool. 9, the hammer is elastically biased toward the center, and when the hammer moves forward without a load, the stopper ball engages with the recess 3a provided on the outer periphery of the hammer, and the hammer stops at the forward limit.
