PURPOSE:To lower the cost through reduction of a number of parts and fitting procedures and also improve appearance by bending, in view of fixing a magnet, the edge of a mounting plate which has a part protruded like a funnel along the part where said permanent magnet is abutted against a ferromagnetic plate. CONSTITUTION:In a structure for fitting a plate 5 which is abutted removably against the vacant edge surface of a permanent magnet 1 to a base plate 8, a mounting plate 9, which is bent in such a manner as wrapping the one side end surface of the plate 5 namely which is provided at the one side end surface and is bent at the circumference along the other side end surface of plate 5, is additionally structured. Thereby, such a mounting plate 9 is formed as a mounting tube part 9a like a bottomless funnel by squeezing almost the center part thereof. In a structure for engaging the mounting plate 9 to the plate 5, more excellent close contactness between the plate 5 and the permanent magnet 1 can be obtained by providing the recessed circumference part 5b corresponding to a thickness of the plate 9 along the outer circumfernce of the plate 5, particularly to the junction area with the magnet 1. |
