A motor includes a motor section, a one-way clutch and an output section. The motor section includes an armature and armature shaft, and the output section includes a worm mechanism having a worm shaft disposed coaxially with the armature shaft. The one-way clutch is disposed between the armature shaft and the warm shaft. The one-way clutch includes a couple of teeth members in engagement with each other, a plurality of rollers for controlling the teeth members, and a spring holding the rollers. The spring urges the worm shaft to separate from the armature shaft.
