In a grinder, a spindle protruding from a main body including a brake device is provided with an inner member. The inner member contacts a pressing portion provided integrally with the spindle and is pressed toward a tip end of the spindle when the spindle is braked by the brake device. A nut member can be screwed on the tip end of the spindle so that a disc-like tool though which the spindle extends perpendicularly can be held between the inner member and the nut member. The inner member comprises a locking member that contacts the pressing portion and is pressed toward the disc-like tool when the brake device is operated, and an inner flange which is detachably attached to the locking member so as to be rotatable together with the locking member. |
