Disclosed is a striking tool technology that contributes to reducing clutch sizes. The striking tool causes a tool bit (119) to perform a striking operation in the long axis direction and to perform a rotational operation about the long axis, thereby causing the tool bit (119) to carry out a predetermined machining operation. The striking tool comprises a tool body (103); a motor (111) which is housed in the tool body (103) and drives the tool bit (119); and a clutch (134) which, on a route where the torque of the motor (111) is transmitted to the tool bit (119), is disposed in a high rotational speed and low torque region that is a stage prior to where the rotational speed of the motor (111) is reduced, which transmits the torque of the motor (111) to the tool bit (119) in a normal state, and which cuts off the transmission of torque generated about the tool bit long axis in the tool body (103) if the torque exceeds a predetermined torque level. |
