Claims

[Scope of utility model registration request]

A magnetic frame formed of a magnetic material, a pair of fixed core and a movable core that correspond within the magnetic frame, and a magnetic frame that is directly or indirectly attached to the movable core so that the movable core acts on the fixed core in the direction of separation. and a tripping spring installed on both sides of the movable core such that when the movable core is in contact with the fixed core, the tripping spring force forms a magnetic circuit in which both cores attract and hold each other. The movable iron core is composed of a pair of permanent magnets placed in the movable iron core, and a tripping coil that is wound around the fixed iron core so as to bias the magnetic flux created by these permanent magnets in a direction that cancels out the magnetic flux created by the permanent magnets. An open type electromagnet comprising a permanent magnet supporter made of a non-magnetic metal or synthetic resin to be inserted, and a guide hole wall portion of a movable core being integrally formed with the permanent magnet supporter.゛
