Abstract
A power tool which has an anvilthat is rotated by a hammerand is housed in a housing, and rotates an output shaftis provided. The anviland the output shaftare integrally formed into one unit, and a carrierthat is rotatable relative to the anvilby a predetermined angle on the same axis is provided. On one portion of an outer circumferential surface of the anvil, a relief surfaceis formed. Cut-out portionsare formed at positions opposed to each other of a carrier, and by allowing an engaging pinto be interposed therein, a locking mechanism that limits the relative rotation between the anviland a lock ringis prepared. When the tool main body is manually rotated while the hammeris being stopped, the engaging pinlimits the relative rotation between the anviland the lock ring. The locked state between the anviland the lock ringis released immediately when the rotation of the motoris started.
