Abstract

A large diameter portion is provided on one side of a closing side drum in an axial direction, a small diameter portion having a diameter gradually decreasing from the large diameter portion to the other side of the closing side drum is provided on the other side of the closing side drum, a partition wall disposed between adjacent small diameter cable grooves in the axial direction of the closing side drum to prevent a closing side cable from slipping out of the small diameter cable grooves is provided in the small diameter portion. Accordingly, the thick partition wall provided in the small diameter portion 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 is changed and transferred from the large diameter portion to the small diameter portion.

Claims3

Dependent claims

A drive unit driving an opening and closing body that opens and closes an opening portion, the drive unit comprising:

a cable pulling the opening and closing body;
a drum having a cable groove on which the cable is wound;
an electric motor rotating the drum;
a large diameter portion provided on one side of the drum in an axial direction;
a small diameter portion provided on another side of the drum in the axial direction having a diameter gradually decreasing from the large diameter portion to the another side of the drum in the axial direction;
and
a slip preventing wall provided in the small diameter portion, disposed between adjacent cable grooves in the axial direction of the drum, and preventing the cable from slipping out of the cable grooves,
wherein a spacing of adjacent cable grooves of the small diameter portion in the axial direction of the drum is greater than a spacing of adjacent cable grooves of the large diameter portion in the axial direction of the drum.
