チにおける衝撃発生機構。 In an impact wrench that includes an impact generating mechanism between a drive source and an anvil, the impact generating mechanism has an input shaft that transmits power of the drive motor, and is loosely fitted to the input shaft and can be freely inserted into and removed from the anvil on one side. The input shaft includes a hammer body having a locking claw, and an elastic member that biases the hammer body toward the anvil, and a plurality of approximately heart-shaped grooves having a predetermined lead angle are formed on the peripheral surface of the input shaft. On the other hand, a locking groove is formed on the inner circumferential surface of the hammer body that substantially faces the heart-shaped groove, and a spherical locking member is rotatably fitted between both grooves. Impact generation mechanism in impact wrench.
