向が選定されている自己保持形ソレノイド。An operation and return coil, a movable iron core whose end protrudes from one end of the operation and return coil and is movable in the axial direction within the coil, and the other end of the movable iron core. A fixed bone made of a magnetic material is provided at the other end of the operating and returning magnet to face the movable iron core and receives it at a position where the movable iron core is attracted. , a magnetic yoke having one end magnetically tightly coupled to one of the movable iron core and the fixed bone and the other end coupled to the other of the movable iron core and the fixed bone via at least one magnetic gap; The yoke is arranged in the moving direction of the movable iron core at the end of the yoke on the magnetic gap side, one magnetic pole is magnetically closely coupled to the other of the movable iron core and the fixed bone, and the magnetic pole of the other force is arranged in the moving direction of the movable iron core. It comprises a yoke and a plurality of permanent magnets that are magnetically tightly coupled, and when the movable iron core is in a returned state separated from the fixed bone, the gap length of the magnetic gap is equal to the length of the movable iron core and the fixed receiving amount. most of the magnetic flux of each of the permanent magnets passes through the magnetic gap in the same direction, and in the operating state where the movable iron core is in contact with the fixed bone, most of the magnetic flux of each of the permanent magnets passes through the magnetic gap in the same direction. is a self-holding solenoid in which the length of the magnetic gap and the magnetic pole direction of the permanent magnet are selected so as to pass through the movable iron core and the fixed bone through their contact surfaces without passing through the magnetic gap.
