PURPOSE: To attain a sufficient vibration countermeasure and prevent the cost increase of the whole device to the utmost by inserting a vibration absorbing member made of an elastic body between a socket main body section and a support member. CONSTITUTION: A vibration absorber 2 made of heat-resistant silicone rubber is inserted between a plug-in socket main body section 1 made of a resin and a support section 3 made of brass or iron for supporting the socket main body section 1. Only the weight of the socket main body section 1 is applied to the vibration absorber 2, and the weight applied to the vibration absorber 2 is made smaller as compared with the conventional one. The vibration absorber 2 can be formed with a material having the softer hardness than before (e.g. heat-resistant silicone rubber), and the vibration absorption characteristic can be improved as compared with the conventional one. Even when a lamp is used under the conditions of vibrations and shocks, the occurrence of the run-out of the lamp can be prevented, the structure of the vibration absorber 2 can be reduced, and its cost increase can be prevented. |
