A device for supporting a cable between a vehicle body and a movable member movably connected to the vehicle body is provided with a guide member including a first opening communicating with a hollow portion of a frame body and used for the insertion of the cable, a second opening spaced apart by a specified angle from the first opening, communicating with the hollow portion and used for the insertion of the cable, and a three-dimensional arcuate surface on the outer surface of the frame body; and a supporting member for rotatably holding the arcuate surface of the guide member. The supporting member is fixed to the vehicle body and/or movable member. The cable is inserted from the first opening of the guide member to the second opening through the hollow portion, so that the guide member can follow angular changes of the cable in vertical, transverse and oblique directions.
