Abstract
A rotation restricting member made of a resilient body such as a leaf spring is driven by a magnet switch upon energization of a motor and engages engaging grooves formed on an outer peripheral surface of an outer portion of a one-way clutch so that the rotation restricting member restricts rotation of the one-way clutch. The motor has first and second field coils connected in parallel. The first field coil is connected to an exciting coil in the magnet switch in series and the second field coil is connected to a motor contact in the magnet switch in series. When a starter switch is actuated, only the first field coil is actuated first with low voltage. Then, the motor contact is closed and the second field coil is actuated also so that the motor rotates at a high speed with full voltage.
