Claims

[Scope of utility model registration request]

an annular stator, an electromagnetic coil built into the annular stator, a guide pin fixed to the inner surface of the peripheral flange of the annular stator and extending in the axial direction of the annular stator; an annular armature that is provided opposite to the inner end surface of the stator and is movable on its axis with the guide pin inserted into its peripheral edge; and an annular armature that is rotatable concentrically with the annular stator on the opposite side of the stator. a rotor provided on the rotor, an annular plate provided on the side opposite to the armature of the rotor and having a guide pin inserted into the peripheral edge thereof, and a ring-shaped plate fitted externally on the guide pin and between the flange of the stator and the armature. In the electromagnetic control device, the guide pin is provided with a spring that is interposed to always separate the armature from the stator and bias the rotor in the direction of pinching the rotor with the plate, and the guide pin has a smooth peripheral surface at its tip. In addition, a retaining ring is protruded to the outside of the annular plate, a retaining ring is fitted onto the protruding tip, and the retaining ring is positioned by bringing the peripheral pressing surface of the retaining ring into contact with the outer surface of the annular plate. electromagnetic braking device.
