<p>PROBLEM TO BE SOLVED: To facilitate the work of separating a decorative plate from a plate frame, by forming a fulcrum when inserting a tool and rotating it, thereby preventing idling of a tool. SOLUTION: The decorative plate 50 is set capable of mounting and removal in such a form that it lies upon the plate from 40 fixed to a work execution plane. An unfastening groove 47 is cut in the plate frame 40, in the butting section of the plate frame 40 and the decorative plate 50. A plate-shaped tool, such as a slotted screwdriver or the like, can be inserted into the unfastening groove 4, and when the tool rotates, the decorative plate 50 is pushed up and comes off the plate flame 40. A stopper 49 is made at the inner flank of the unfastening groove 47, and the flank in width direction of the tool is inserted into the whirl stopping groove 49a provided at the flank of the stopper 49, and the tool rotates, with the stopper 49 as a fulcrum.</p> |
