から成る電磁石において、 該可動鉄心は一対の鉄片から成り、該一対の鉄
片は所定間隔をおいて永久磁石を挟持し、該可動
鉄心の変移方向と該永久磁石の磁化方向が同一に
なるように該永久磁石は設けられ、該電気巻線に
無通電のときに、該所定間隔が該ヨークの端部に
ほほ対面するように該可動鉄心が設けられたこと
を特徴とする電磁石。[Scope of claim for utility model registration] A yoke, a fixed core fixed to the yoke,
A movable core displaceable with respect to the fixed core, a spring that urges the movable core to move away from the fixed core, and a magnetic path consisting of the yoke, the fixed core, and the movable core. and an electric winding that attracts the movable iron core to the fixed iron core against the biasing force of the spring when energized, the movable iron core consists of a pair of iron pieces, and the pair of iron pieces Permanent magnets are sandwiched at a predetermined interval, and the permanent magnets are provided so that the direction of displacement of the movable iron core is the same as the magnetization direction of the permanent magnet, and when the electric winding is not energized, the permanent magnet An electromagnet characterized in that the movable iron core is provided such that the movable core is spaced so that it almost faces the end of the yoke.
