Abstract
Cable guides for keeping the push-pull cable in mesh with a pinion are effectively reinforced by a member connecting the free ends of the cable guides. In particular, even when the cable guides are made of a plastic member, and the push-pull cable drive unit is subjected to high temperature environments, the meshing between the cable and the pinion is ensured. Thus, the present invention provides a stable and reliable operation of the push-pull cable drive unit with a simple and economical arrangement. This arrangement is particulalry useful for automotive sunroofs.
Claims8
A push-pull cable drive unit assembly, comprising:
- a main assembly integrally incorporated with an electric motor and a speed reduction unit;
- a pinion projecting from a casing of said main assembly and attached to an output end of said speed reduction unit;
- a pair of runs of push-pull cable extending parallel to each other and meshing with said pinion at diametrically opposite sides thereof;
- a pair of cable guides projecting from said casing to support the corresponding runs of said push-pull cable against movement away from each other;
- and
- a bridge member placed across said cable guides for restricting movements of free ends of said cable guides away from each other, wherein said bridge member comprises a member connecting free ends of said cable guides.
