ABSTRACT:
A driver drill that can effectively prevent erroneous clutch operation in a drill mode is provided. A flat washer positioned between steel balls for locking an internal gear and a coil spring is rotatable by rotative operation of a mode-change ring. Also, protruding streaks are provided on a small-diameter unit of a second gear case around which a flat washer is externally mounted. The protruding streaks interfere with internal projections on an inner circumference of the flat washer at its predetermined rotating position to regulate a forward movement of the flat washer. When a drill mode is selected with the mode-change ring, the flat washer is locked by the protruding streaks.
