<p>PURPOSE:To give a flexible piece on the movable side rigidity by engaging one engaging piece of a wiring instrument with the first stepped section of the flexible piece on the movable side, abutting and positioning the other engaging piece along an inclined face on the fixed side and deflecting the flexible piece in the cross direction. CONSTITUTION:A plate frame body 1 is installed onto the front of the opening surface of a burying box buried to a wall surface, etc., and slitty and circular mounting holes 6, 7 are bored to the upper and lower sections of the plate frame body 1 respectively. An internal piece 9 and an external piece 10 are formed integrally in parallel through a clearance in one side piece 8 of the plate frame body 1. 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 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 displaced only in the cross direction, thus giving the flexible piece 11 regidity.</p> |
