Claims

[Scope of Claim for Utility Model Registration] (1) A winding drum for winding a cable in a housing, and a brake drum having a coil spring wrapped around the inner circumferential wall for braking of the housing that can slide on the inner circumferential wall for braking of the housing to generate brake force. In the drive device for a window regulator, the drive device accommodates a brake, supports both drums rotatably about a drive shaft, and moves up and down by connecting a window glass to the tip of the cable. A circular storage recess centered on the drive shaft is formed in the drum, the housing is dropped into a cylindrical shape along the circumferential wall of the storage recess, and the dropped portion is aligned with the circumferential wall of the storage recess. A pivot part that can be rotated while sliding around the circumference, and a part that is continuous with the pivot part is raised again,
A drive device for a window regulator, characterized in that the inner peripheral wall for braking is in sliding contact with the coil spring wound around the brake drum. (2) A hook piece having a vertical cross section is fixed to the base end of the cable, while a hook piece having a longitudinal cross section is fixed to the outer peripheral edge of the winding drum.
Claim 1 characterized in that the hook piece is formed with a locking groove into which the hook piece is fitted and locked in a vertically elongated state.
A drive device for the window regulator described.
