間を反転移動するよう構成される。FIG. 3 shows a configuration diagram of a conventional monostable polarized electromagnet floating prevention device. In FIG. 3, the armature 12 penetrates through the inside of the coil 11 wound around the coil frame 21, and one end 13 of the armature 12 is opposed to the tips of two yokes 15 and 16 arranged via a permanent magnet 19. Piece 1
It is arranged between 7 and 18. On the other hand, the other end 14 of the armature 12 is provided at the other end of the yoke 16 and is disposed along a hinge end 20 bent into an L shape. One end 13 of the armature 12 has two yoke facing pieces 17 and 18.
It is configured to reversely move between.

特性も不安定になる。On the other hand, when a current is applied to the coil 11 to excite the magnetized poles of the yokes 15 and 16 due to the magnetism of the permanent magnet 19, one end 13 of the armature 12 repels one end 17 of the yoke 15. It is sucked by one end 18 of the yoke 16 and moves in reverse. Further, a magnetic repulsive force acts on the other end 14 of the armature 12 and the hinge end 20 such that a gap is formed therebetween. When such a gap occurs, the efficiency of the magnetic circuit decreases, and the operation and the open-circuit voltage characteristics become unstable.

In order to prevent the occurrence of a gap between the pressure member 4 and the hinge end 20, a pressing member 23 formed of an elastic metal is prepared.
3, the other end 14 of the armature 12 is sandwiched between the other end 14 of the armature 12 and the hinge end 20, and the pressing force of the clamping member 23 is configured to exceed the repulsive force. The end 20 is kept in close contact, the lifting of the hinge portion 20 can be prevented, the efficiency of the magnetic circuit can be prevented from lowering, and the open-circuit voltage characteristics can be stabilized.
