PURPOSE:To correct shift of engaging position between engaging devices produced during manufacturing, assembling and use, by a method wherein one of engaging devices having a permanent magnet is installed so that it may be oscillated in all directions with respect to the attaching level. CONSTITUTION:A non-magnetic case is provided at bottom surface with a flange 4a which is communicated to a hole 1a of a permanent magnet and engaged to end edge of the hole 1a. A ferromagnetic plate 2 is attached to pole surface of the magnet 1 and pawl 4b at opening end of the case 4 is bent for the integral covering. A narrowed lever 2b of a ferromagnetic lever 2a is fitted to the plate 2, and the lever 2a is projected to the hole 1a. The lever 2b is slidably inserted through a gap x to a hole 5' of an angle 5, and a cushion material 7 is interposed to the gap (x) thereby a knob 6 having tapered surface is fixed. In this constitution, the engaging device is composed of a ferromagnetic plate 3 and a lever 3a thereof in elastic region of the cushion 7 and follows other device and oscillates, thereby good attaching state between surfaces of the levers 2a, 3a by magnetic force is always realized. |
