DRIVE UNIT AND METHOD FOR ATTACHING SAME

The present invention provides a drive unit and a method for attaching the same with which it is possible to improve the ease of attaching the drive unit to an attachment object. A limiting member is configured so as to limit the rotation of a drum when a lock member has fixed a pulley in a first position, and to allow rotation of the drum when a coil spring has caused the pulley to move to a second position. This makes it possible to prevent rotation of the drum in the state (vehicle mounting preparation state) before attaching the drive unit to a vehicle body. Therefore, it is possible to prevent a pair of cables from loosening inside a drum housing and catching on other constituent components. Accordingly, it is possible to improve the ease of attaching the drive unit to a vehicle body.
