| A compact-size electromagnetic clutch reaches a blocking state as an electromagnetic solenoid is switched from a non-driving state to a driving state and can save wasteful consumption of energy under this blocking state. This electromagnetic clutch includes a wrap spring in pressure-contact with an outer face of a cylindrical portion of a drive pulley provided on the center side thereof. One end of the wrap spring is coupled to a drive arm of a drive member operably connected to a shaft. The other end of the wrap spring is coupled to an operational member rotatable relative to the shaft and movable along the rotational axis thereof. An electromagnetic solenoid attracts the operational member. An operational mechanism permits realization of the blocking state by preventing rotation of the drive member after a twisting operation of the wrap spring subsequent to the attraction of the operational member by this electromagnetic solenoid. | ||||||

| Provided is an electromagnetic clutch, in which a plurality of magnetic flux shielding slits extending in the axial direction and arcuately in the circumferential direction are formed individually in a rotor and an armature, and in which the magnetic flux by the excitation of a coil inserted on the anti-armature side of the rotor is passed from the non-slit portion of the rotor to the non-slit portion of the armature and from the non-slit portion of the armature to the non-slit portion of the rotor, so that a magnetic attraction is generated to bring two frictional faces into press contact with each other and so that the two frictional faces are separated by the demagnetization of the coil. The slits of at least one of the rotor and the armature are formed to change in such a taper shape that the slit width at the frictional face side may be smaller than that at the anti-frictional face side. Without inviting any drastic cost increase, the mutual press-contact force of the frictional faces can be enhanced so that a higher torque transmission may be possible with the same size as that of the conventional structure. | ||||||

| In this electromagnetic clutch, a compressive force is generated in a plate spring when an armature plate is contact with a first rotor. Therefore, a force in the direction away from the first rotor acts on a first bent portion of a plate spring. However, an extension portion of a second rotor is capable of abutting to the first bent portion from the direction opposite to the first rotor. So a stress generated in the first bent portion is dispersed to the extension portion. | ||||||
