<p>PURPOSE:To give the movable side rigidity by forming only a movable section, to which the engaging piece of a wiring instrument is inserted and engaged previously, in flexible structure. CONSTITUTION:A movable section 34 is shaped to one side piece 8 of a plate frame body 1. That is, the internal piece 9 and external piece 10 of the side piece 8 are formed integrally in parallel through a clearance, and a flexible piece 11, upper and lower ends of which are unified with the plate frame body 1 and which has flexibility, is shaped in the clearance between both side pieces 9, 10. The internal surfaces of both side pieces 9, 10 are bonded by bridging pieces 12, 13 at two positions on both sides of the flexible piece 11. A slit 14 is formed to the external piece 10, the external piece 10 is shaped in a thin piece 15, a section on the inside of which is thinned, the bridging piece 12 is combined with the thin piece 15, and the flexible piece 11 is easy to be deflected. The flexible piece 11 is formed so as to be deflected in the cross direction as shown in the arrow. Accordingly, the flexible piece 11 is only displaced in the cross direction, thus giving the flexible piece 11 rigidity.</p> |
