PURPOSE: To prevent a malfunction such as an injury of fingers and damage of cord covering by improving operability of a set spring to be used to fix a bulb to a bulb installing hole. CONSTITUTION: In a set spring 8 to fix a bulb by elastically pressing a base flange 7 of a bulb 5 to an installing metal fitting 9 arranged in a bulb installing hole 4, its tip part 8d can be hooked to a hooking part 11a arranged in the installing metal fitting 9, and its part 8e is constituted so as to be elastically contacted with the base flange 7 in its hooking state. This tip part 8d is formed by being bent inside, and is hookingly fastened to the hookingly fastening part 11a in its bent inside end part. In the case where the set spring 8 is deflected, when it is operated by contacting fingers over the tip part 8d and an operation part 8c formed so as to continue with this, the fingers do not become painful, and the sharp tip does not contact with the fingers, and operability is improved, and an injury and damage of covering can be prevented. |
