<p>PROBLEM TO BE SOLVED: To prevent the rubbing of an inner cable to the side wall of a pulley groove by a simple structure, at the separation point in which the inner cable is separated from the pulley groove. SOLUTION: When a pulley 11dr is rotated in right/left by the operation of a handle, the separation point in which an inner cable 5i is separated from a pulley groove 111 is moved from P at the neutral time to P1 or P2. Consequently, the inner cable 5i is bent at the separation points P1, P2 and an abnormal sound and wear are generated by the rubbing of the inner cable 5i to the side wall near the center surface CP of the pulley groove 111. In order to prevent this, the side wall near the center surface CP of the pulley groove 111 is made to a slant wall 114 so that the inner cable 5i is not rubbed. The slant angle of the slant wall 114 is changed continuously so as to become bigger as the pulley groove 111 separates from the center surface CP.</p> |
