Abstract (en)

A power tool includes: a motor that serves as a rotational power source and is rotatable in a normal rotation direction and a reverse rotation direction; an output unit that is driven by the motor to be rotated; and a transmission that is located between the motor and the output unit and switches a reduction ratio. The power tool further includes a control means. The control means makes the transmission perform switching operation of the reduction ratio in response to a workload, and changes an initial reduction ratio in the transmission when work is started, in response to a rotation direction of the motor. The initial reduction ratio is set as the reduction ratio in an initial setting.
