It is an object of the invention to improve dustproof effect for a impacting tool. The representative impacting tool has a tool holder 153 and a locking part 157. The locking part 153 can be driven to move between the bit holding position, where it is engaged with the tool bit 119 inserted into the bit inserting hole 153a with respect to the tool holder 153 so that pullout is restrained, and a bit holding released position where the engagement is released and pullout is allowed. In addition, the locking part 157 and the tool holder 153 can be integrated with each other while moving in the longitudinal direction of the tool bit, so that they can be driven to move between the bit anchored position where the locking part 157 is set at the bit holding position and the engagement state with respect to the tool bit 119 is maintained, and the bit last connection/disconnection allowed position where the locking part 157 is set at the bit holding released position and releasing of the engagement with respect to the hammer bit 119 is allowed. |
