ABSTRACT:
An electromagnetically controlled spring clutch mechanism comprising an input rotating element, a rotor, an armature, a biasing spring for biasing the armature in a direction away from the rotor, an electromagnetic driver for magnetically attracting the armature to the rotor against the biasing action of the biasing spring, and a coil spring. The clutch mechanism transmits the driving force of the input rotating element by the contraction of the coil spring. According to a first aspect, the biasing spring is fixed to a supporting member by a plate-like spring fixing member to form a unit assembly. According to a second aspect, the clutch mechanism can be used in any one of two arrangements by changing the assembling sequence of various constituent elements. According to a third aspect, projections which contact or approach the rotor beyond the armature are provided in the supporting member, to which one end of the coil spring is connected. According to a fourth aspect, an improvement is made on the electromagnetic drive, which can be applied not only to the electromagnetically controlled spring clutch mechanism, but also to other types of electromagnetic clutch mechanisms.
