Abstract
A torque transmission mechanism includes a magnet coupling including a driving magnet member coupled to a side of driving shaft driven into rotation by a motor and a driven magnet member coupled to a side of an output shaft on which a front-end tool is attachable. A clutch mechanism is provided between the motor and the torque transmission mechanism. A moment of inertia on the side of the driven magnet member is larger than a moment of inertia on the side of the driving magnet member.
