Abstract
PURPOSE:To obtain a magnetic securing device which can easily operate to switch a magnetic operating face between an exciting state and a nonexciting state and has a large attracting force by providing a pair of magnetic members interposed at both sides of a nonmagnetic member, and providing a specific magnetic circuit block having a magnetic operating face and a specific permanent magnet assembly. CONSTITUTION:A pair of magnetic members 24, 26 interposed at both sides of a nonmagnetic member 28, a magnetic circuit block 22 having magnetic operating faces 32 of the members 26, 26 and a space 34 specified by at least a pair of opposite flat faces 38 to cross a shaft 40 extending along the members 24, 26 between the members 24 and 26, and a flat plate-like permanent magnet assembly 44 so disposed in the space 34 rotatably around the shaft 40 as to selectively switch the faces 32 between an exciting state and a nonexciting state are provided. The assembly 44 has pole faces 54-60 opposite to the flat faces 38 on both side faces.
