Claims

[Scope of Claim for Utility Model Registration] A connecting body is fixed to one end of a stator containing an excitation coil, and a lining is fixed to the other end, and an armature is attached by forming a suction gap in the axial direction on the lining surface. let me,
A spring plate is riveted to the outer periphery of the back of the armature, and a protruding ring plate is protruded from the inner side, so that the inner periphery of the spring plate is fixed. It is fitted into a hub protruding from a torque transmission shaft so as to be movable in the axial direction, and torque transmission pins are press-fitted in the axial direction at a plurality of locations on the fitting surface, and a shaft is provided on the outer side facing the protruding ring plate. A protruding wheel plate is fixed to a boss formed by protruding a protruding ring plate to form a set gap in the direction, and when the suction gap is smaller than the set gap, the pressing force of the torque transmission pin is greater than the spring force of the original spring plate. An electromagnetic coupling device characterized in that when the suction gap becomes larger than the set gap, the boss is moved in the axial direction by the coil attraction force by an amount exceeding the set gap.
