Abstract

PURPOSE:To economize and secure engagement as well, by employing a plastic magnet as a permanent magnet with an engaging hole, and by combining a ferromagnetic plate with it. CONSTITUTION:A plastic magnet 1 has an engaging hole 1a through one side of its magnetic pole surface to the opposite surface. A ferromagnetic plate 2 is integrally buried and fixed to one side of its magnetic pole. This is inserted and integrally formed when the magnet 1 is formed. Another ferromagnetic plate 3 is set magnetically detachably on an empty magnetic pole side against the magnet 1. A ferromagnetic plate 3a, projected from the plate 3, has a magnetic contact with the plate 2 through a hole 1a of the magnet 1. Thus, a direct contact without any covers ensures stronger magnetic attachability and secures engagement. Less parts make lower prices.
