Abstract

An impact wrench capable of preventing "reverse hammering", "slipping hammering" and "double hammering" from occurring. By using, a frictional resistance value between a shaft support part and a rotating hammer support body can be adjusted to such a frictional resistance value that the rotating hammer support body is rotated following the process of rotation of the hammering receiving part. As a result, the hamming part can be back to the maximum rebound position during the reverse rotating direction.
