Abstract
It is an object of the invention to provide an effective technique for achieving a smooth driving operation with a driving power tool for driving a driving material into a workpiece. A representative driving power tool for driving a driving material into a workpiece is provided with a coil spring, an operating member. The power tool fixer includes a rotating element that rotates in a normal direction it the spring force of the coil spring as the drive member drives the coil spring, an outer edge of the rotating element, an engaging member and a lock avoiding mechanism. The outer edge includes a first outer edge portion and a second outer edge portion, a first vertical wall and a second vertical wall. The engaging member defines a working stroke of the driving operation. The lock avoiding mechanism avoids the engaging member from being locked to the second vertical wall by the spring force of the coil spring being transmitted to the engaging member via the second vertical wall in the process in which the engaging member moves inward in the radial direction of the rotating element toward the second outer edge portion via the second vertical wall.
