Abstract
A battery-operated driver-drill () includes an epicycle reduction gear unit () which encases a switchover sleeve () having inner teeth () and outer teeth (). The gear unit () is rotatably mounted on second and third internal gears () and integrally slidably connected with a slide pate (). By operating the slide plate (), the switchover sleeve () may be slid between a first position, in which the slide plate () engages one of the second and third internal gears () while engaging axial ridges () of a first gear case (), and a second position, in which the slide plate () simultaneously engages both the second internal gear () and a first carrier () adjacent to the second internal gear () while disengaged from the axial ridges ().
