Abstract: PROBLEM TO BE SOLVED: To improve the yield of a material and to inexpensively manufacture a device by providing an armature movable together with a rotor in the axial direction via a gap, supporting this armature via a spring, providing a hub rotatable on a shaft and constituting the spring into an integrated rectangular shape. SOLUTION: When voltage is impressed on a coil 2 via lead wire 3, magnetic flux Φ is generated in a magnetic path shown by a dotted line, and an armature 6 overcomes elastic force of a spring 8 by the suction force and is sucked by a rotor 4. Therefore, the armature 6 is brought into contact with the rotor 4 and power transmitted to a gear 7a is transmitted to load via a hub 7, the spring 8, the rotor 4 and a shaft 5. Because armature mounting holes 6a are located at two portions, deformation on a friction surface of the armature 6 when a rivet 9 is caulked is reduced and rated torque becomes easy to be generated from initial period. Because the spring 8 is formed into an integrated rectangular shape, the yield of a material is remarkably improved and this device can be inexpensively manufactured.
