PURPOSE: To enable installing a reflector on a base plate in easily attachably and detachably, certainly and compactly by restraining the reflector on the base plate only at two points. CONSTITUTION: After a lug 1a of the reflector 1 is hooked at a restraining part 2a of the base plate 2 from the arrow (1) direction, a lug 1b is dropped in a restraining part 2b in the arrow (2) direction and the reflector 1 is rotary- moved in the arrow (3) direction by using the lug 1a as a fulcrum, and then, a positioning pin 1c of the reflector 1 is inserted into a positioning hole 2c of the base plate 2 (in the arrow (4). Since the lugs 1a, 1b and the positioning pin 1c of the reflector 1 are positioned at both ends in a longitudinal direction of the reflector 1 and form a prolate triangle in which the lug 1a is a vertex, the reflector 1 is rotary-moved by a hooking quantity of the lug 1b within restriction of the lug 1a being the fulcrum by maintaining the distance between the lug 1a and the lug 1b, and then, the rotary moving is stopped by the positioning pin 1c to fix the reflector to the base plate. Finally, after the reflector 1 is installed on the base plate 2, an LCD 3 is rotated in the arrow (5) direction to fix and hold the LCD 3 on the reflector 1. |
