Claims

[Claims for Utility Model Registration] 1. A striking device driven by a motor is provided in the main body, the output shaft of this striking device protrudes from the front end of the main body, and an engaging tool attached to the front end of the output shaft is connected to a bolt or the like. In an impact wrench that rotates when engaged with a nut, a torsion bar is attached to the output shaft, an engagement tool for a bolt or a nut is provided at the tip of the torsion bar, and a timer is further provided to control the rotation time of the motor. Impact wrench provided. 2. An impact wrench as set forth in claim 1 of the utility model registration claim in which an output shaft and a torsion bar are integrated. 3. The impact wrench as set forth in claim 1 of the utility model registration claim, in which a torsion bar can be attached to and detached from the output shaft.
