ABSTRACT:
An electromagnetic clutch wherein a rotational force is transmitted between a first rotatable member and a second rotatable member by a magnetic attraction of an armature supported on one of the first and second rotatable members to the other member. The armature is rotatable with respect to the member upon which it is mounted within a limited extent. At least one arcuate spring member is provided to connect the armature and the supporting member. The inner surface of the arcuate member faces the annular surface of a portion of the other rotatable member. When the armature is magnetically attracted to, and rotated together with, the other rotatable member, the inner surface of the arcuate spring member comes into contact with an annular surface of the other rotatable member so that the transmission of the rotational force is effected through the arcuate spring in addition to the magentic attraction of the armature.
