Abstract
A motorized retractor which includes a spool with a webbing wound therearound, a reversible motor, a forward and a reverse driving force transmission mechanisms. The forward and the reverse driving force transmission mechanisms are provided between the spool and an output shaft of the motor, respectively. The forward driving force transmission mechanism reduces forward rotation of the output shaft by a predetermined reduction ratio and transmits this rotation to the spool for rotating the spool in a winding direction. The reverse driving force transmission mechanism reduces reverse direction rotation of the output shaft by a reduction ratio which is lower than the predetermined reduction ratio of the forward driving force transmission mechanism, and transmits this rotation to the spool for rotating the spool in the winding direction. The forward and the reverse driving force transmission mechanisms both block transmission to the output shaft of rotations generated at the spool side.
