具の可変速歯車装置。 A differential gear mechanism is installed in a gear case fixed to a housing, etc., and an intermediate gear is interposed on at least one of the output sides so that the rotation directions of the inner and outer output shafts of the differential gear mechanism are the same. , a clutch mechanism is interposed, and a protrusion is formed on the outer circumferential surface of the internal gear of the last planetary gear mechanism in the differential gear mechanism so that it can be freely engaged with and disengaged from the torque setting cam, and the first planetary gear in the differential gear mechanism The fixing and unfixing of the internal gear of the gear mechanism is linked to the axial movement of the internal gear of the final planetary gear mechanism, and a damper with an appropriate spring constant is provided at one or more places in the transmission system of the differential gear mechanism. A variable speed gear device for a rotary power tool, characterized in that:
