  • Patent number: 6283452
    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.
