Abstract
An electromagnetic clutch includes a first rotatable member supported on a first bearing, and connected to an external driving source having an axial magnetic end plate. A second rotatable member is connected to a driven member. An annular magnetic member is supported on the second rotatable member through a plurality of leaf springs so as to be capable of axial movement, and faces the axial end plate of the first rotatable member with an axial gap therebetween. A third rotatable member is connected to the second rotatable member, to limit the axial movement of the annular magnetic member. An electromagnet is associated with one of rotatable members and the annular magnetic member for transmitting rotational force from the external driving source to the other of the rotatable members. Plural resilient core connecting devices are fixed between the annular magnetic member and the third rotatable member, to absorb vibration and impact noise at the time of attraction of the annular magnetic member to the first rotatable member, as well as support the annular magnetic member.
