Claims

[Scope of utility model registration request]

The bobbin around which the coil is wound is movable in the axial direction within the center opening, and both ends protrude from the center opening, and each protrusion has a suction plate, and each suction plate has an axially outward facing surface and an inwardly facing surface. a pair of opposing side portions each having a suction surface facing inwardly in the axial direction of each suction plate, and a pair of opposing side portions each having a suction surface facing inward in the axial direction of the suction plate; a first yoke comprising a connecting portion located and connecting the pair of side portions to each other; a pair of opposing side portions each having a suction surface facing an axially outward suction surface of the other of the suction plates; and a suction surface which connects the pair of side parts to each other and which faces the suction surface facing outward in the axial direction of the one suction plate, and intersects the connecting portion of the first yoke in a cross shape. A bistable polar electromagnet, comprising: a second yoke consisting of a connecting portion located at the yoke; and a permanent magnet provided between the intersecting portions of the connecting portions of the first and second yokes. .
