Abstract

The invention provides a drive unit capable of reliably preventing a cable from falling off even if one side and the other side of a drum in the axial direction have different diameters. A large diameter portion (74) is arranged on one side of a closing side drum (70) in an axial direction, a small diameter portion (73) having a diameter gradually decreasing from the large diameter portion (74) tothe other side of the closing side drum (70) is arranged on the other side of the closing side drum (70), a partition wall (73b) disposed between adjacent small diameter cable grooves (73a) in the axial direction of the closing side drum (70) to prevent a closing side cable from slipping out of the small diameter cable grooves (73a) is provided in the small diameter portion (73). Accordingly, thethick partition wall (73b) provided in the small diameter portion (73) can reliably prevent the closing side cable from slipping out (derailing) from the small diameter cable grooves even when a winding position of the closing side cable on the closing side drum (70) is changed and transferred from the large diameter portion (74) to the small diameter portion (73).

Description

technical field [0001] The present invention relates to a drive unit that drives an opening and closing body that opens and closes an opening. Background technique [0002] On the side of a vehicle such as an automobile, an opening is provided for passengers to get on and off the vehicle, or to access cargo. The opening is opened relatively widely, and is opened and closed by a sliding door that moves along slide rails provided on the vehicle body. Since the sliding door is heavy, a vehicle including the sliding door is equipped with a sliding door opening and closing mechanism capable of automatically opening and closing the sliding door. [0003] The sliding door opening and closing mechanism includes a driving unit. A pair of cables that pull the sliding door are provided on the drive unit. The driving unit includes a pair of rollers on which the cables are wound in opposite directions, and the pair of cables are respectively moved by rotating the rollers forward or ba...
