Claim 7:
8. The power tool according to claim 1, wherein
the reducer includes a third internal gear in a rotatable manner, the third internal gear is slidable in the axial direction between a first slide position and a second slide position, the first slide position is a position at which the third internal gear is restricted from rotating in a case housing the reducer and revolves a third planetary gear, and the second slide position is a position at which the third internal gear is not restricted from rotating in the case and meshes with the third planetary gear and a corresponding carrier of the carriers, and
restricting rotation of one of the preceding internal gear and the succeeding internal gear performed by the engagement member is combined with setting a slide position of the third internal gear to allow selection from three or more variable speeds.
