PURPOSE:To prevent the occurrence of rust by a method wherein the surface of a fancy button in an engagement tool is coated with a resin layer. CONSTITUTION:A ferromagnetic metal plate 2 is attached to one magnetic pole face 1a of a permanent magnet 1, and a ferromagnetic metal plate 3 is abutted to the other magnetic pole face 1b magnetically detachably. A ferromagnetic lever 3a is projected from the central section of the magnetic metal plate 3, and a ferromagnetic lever 2a abutting to and attracting the free end section of the lever 3a is projected from the magnetic metal plate. The permanent magnet 1 and the magnetic metal plate 2 are unitarily attached to each other by a case 7. A mounting pipe 7 having an opening at the upper face is stood on and attached to the end face opposed to the projected levers 2a, 3a. A mounting pipe 5 is attached to the lower face of a separately arranged fancy button 6 having a resin layer 8 on the surface, and the mounting pipe 5 is engaged with and attached to the mounting pipe 4. This prevents the occurrence of rust and permits the selection of color meeting a ground color for the mounting pipes. |
