The nearly U-shaped frame body 11 has its both ends opposed to and coupled with the rim ring 10 in its radius direction, and supports a reflector 2 having an opening 20 at a periphery side. The guide plate 12 thrusts from the center part of the frame body 11 to be in parallel with the rim ring 10, and a bracket 5 with a socket electrode 3 mounted gets insertion-coupled in free sliding movement between both side edge parts folded. A long hole 120 fitted to the guide plate 12 and a screw hole 50 at a corresponding position fitted on the side face of the bracket 5 are linked with a fixing screw 7. <P>COPYRIGHT: (C)2003,JPO |
