ABSTRACT:
A cable operated control device includes a movable control member, a frame coupled to the movable control member, and a cable guide member mounted to the frame for rotation around a guide member axis. The cable guide member includes a curved outer peripheral cable guide surface disposed radially outwardly from the guide member axis for guiding the cable. A bearing having a cable guide surface is disposed radially outwardly from the outer peripheral cable guide surface. When the cable guide member has a small radius of curvature, the cable may contact the bearing and thus avoid the excessive friction encountered in the prior art.
