Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce consumed current of a motor, to improve the screwing speed and to increase the working amount per charging of a charging type battery by reducing the friction torque between an anvil and a spindle generated in screwing work. SOLUTION: A steel ball is interposed in a clearance between a fitting shaft of the spindle and a fitting hole of the anvil, and the average radius R of a contact part of an abutting part of the spindle and the anvil is made small, thereby reducing the friction torque.
