Abstract (en)
[origin: EP2708329A1] A power tool that suppresses unexpected changes in the speed reduction ratio. A control unit (23) controls a gear shift actuator (27) to shift a speed reduction ratio of a power transmission unit (22) in accordance with the detected load torque. After shifting the speed reduction ratio, when a ring gear (RG) is not located at a target position corresponding to the shifted speed reduction ratio, that is, when a cam (30) is not located at a first engagement position or a second engagement position, the control unit (23) uses the gear shift actuator (27) to pivot the cam (30) again and move the ring gear (RG).
