<p>PURPOSE:To provide a bistable electromagnet unit having simple structure and excellent operating function. CONSTITUTION:A central yoke member 12 and the opposite side yoke members 13, 14 are arranged at a predetermined interval and coupled through coupling parts 15. A bobbin 17 applied with a coil 16 is fitted to the central yoke member 12. A movable core frame 20 having two leg parts 20a coupled through a coupling part 20b is also provided while holding a permanent magnet 20 therein and the leading end of the leg part 20a is advanced between the central yoke member 12 and the opposite side yoke members 13, 14 thus constituting a movable attraction member 19. A gap 22 is formed, as a leak magnetic path, at the coupling part 20b of the movable core frame 20.</p> |
