<p>In a grinder 1, a spindle (16) protruding from a main body (10) including a brake device (50) is provided with an inner member. The inner member contacts a pressing portion (16A and 16B) provided integrally with the spindle (16) and is pressed toward a tip end of the spindle (16) when the spindle (16) is braked by the brake device (50). A nut member (40) can be screwed on the tip end of the spindle (16) so that a disc-like tool (45) though which the spindle (16) extends perpendicularly can be held between the inner member and the nut member (40). The inner member comprises a locking member (20) that contacts the pressing portion and is pressed toward the disc-like tool (45) when the brake device (50) is operated, and an inner flange (30) which is detachably attached to the locking member (20) so as to be rotatable together with the locking member (20).</p> |
