<p>PURPOSE:To enable to align the one-sided load of outside spring by a method wherein an armature is shifted in such a manner that a magnetic circuit is formed by the armatue having a permanent magnet, the first yoke, the second yoke whereon a coil is wound around and the third yoke, thereby enabling to suddenly increase the magnetic attraction of the armature. CONSTITUTION:On the first yoke 30, the inner surface of the left side piece 31 is used as an armature face 31a and the inner surface of the right side piece 32 is used as an armatue face 32a. Both outside surfaces are used as armature faces 35a and 35b on the third yoke 35. Also on the yoke 35, the surface opposing to the coupling rod 39 of the armature 37 is used as an armature face 35c. On the armature 37, the inner and outer faces of an armature plate 40 are used as armature faces 40a and 40b, and the inner and outer surfaces of an armature plate 41 are used as armature faces 41a and 41b. Also, on the coupling rod 39 of the armature 37, the inner surface is used as an armature face 39a. Air gap 39A is located between armatures 35c and 39a. The armature 37 moves horizontally by applying current on the coil 36.</p> |
