Abstract
In a speed change device of an electrical power tool, a reset arm is provided separately from a switch lever, which arm is operated by a reset motor. Due to tilting motion of the reset arm, a lock ring can be returned to an unlocking position in which a second stage internal gear can be rotated, so that the speed change device can be rest to a high speed low torque mode.
