<p>PURPOSE:To simplify the constitution of a engaging device and strengthen the magnetic attractive force, by a method wherein top end of a male engaging member is inserted along pole surface of a magnet and detachably abutted to portion of a ferromagnetic plate rising from lower portion of the magnet. CONSTITUTION:A non-magnetic case 1 has an opening at bottom surface, and a permanent magnet 4 is fitted to the opening so that a gap 3 to which a male engaging member 2 is inserted through a hole 1a remains. End of a ferromagnetic plate 5 is attached to lower surface 4a of the magnet and stands to side of a pole surface 4b along a lateral surface 4c. The top end of the male engaging member 2 is inserted through the hole 1a along the pole surface 4b and detachably abutted to a rising portion 5a of the plate 5 by magnetic action for engagement. In this constitution, cost for preparing and attaching the case is reduced particularly, and the sense of beauty is held in appearance, shape, color and lust.</p> |
