Abstract
A bushing is provided for placement on a cable to be held between an upper cover and a lower cover of an apparatus. The bushing has a flange on an outer peripheral surface thereof, and the flange extends perpendicular to the cable on which the bushing is put. The upper cover and the lower cover of the apparatus are attached to form a unit, and the upper cover comprises a flange receiving portion. The flange comes closely into contact with the flange receiving portion to fix the cable against the upper cover and serve as a watertight packing. As a result, a simple watertight structure is provided.
