<p>PURPOSE:To smoothen the movement of the reversed part of a flexible cable received in a space and prevent the flexible cable from being bent in the course leading the reversed part. CONSTITUTION:A flexible cable 3 wound on an outer cylinder part 8 is wound reversely on an inner cylinder part 9 through a U-shaped reversed part 3a, and recessed grooves 14, 15 are provided on the bottom plate 7 of a lower case and the top plate 10 of an upper case 2 corresponding to the rotating orbit of the reversed part 3a. At the time of the winding fastening or winding loosening operation of the flexible cable, the reversed part of the flexible cable is moved in the same direction as a movable body, but the frictional force is reduced by the recessed grooved present on the rotating orbit, so that the flexible cable can be smoothly delivered in the reversed part direction.</p> |
