PROBLEM TO BE SOLVED: To permit a power cable to undergo a feed wiring process easily and protect a bulb such as glow lamp, jujube-form bulb, etc., from vibration and impact. SOLUTION: An insert hole 2 of a bushing 1 has a dimension of 21 mm as admitting insertion of two VVF cables at one time. If each detent pawl 3 furnished at one surface of the bushing 1 is inserted through a wire threading hole 10 furnished in the body of a luminaire, the detent pawls 3 are engaged fast by the peripheral edge of the hole 10, which causes the bushing 1 to be fitted in the hole 10. Because the diameter of the hole 2 is made 21 mm, it is possible to insert as well a glow lamp as a jujube-form bulb in the insert hole 2 of the bushing 1. It is possible that power cables for drawing-in and feeding are at one time inserted through the hole 2, which should facilitate the feed wiring process, and by the bushing 1, bulb such as glow lamp, jujube- form bulb, etc., can be protected from vibration and impact by inserting the bulb through the hole 2. |
