Title:
ELECTROMAGNETIC CLUTCH MECHANISM
Document Type and Number:
WIPO Patent Application WO/2017/170431
Kind Code:
A1
Abstract:
The present invention pertains to an electromagnetic clutch mechanism provided with: a driving side rotor (30); a driven side rotor (40); an electromagnet (51); a leaf spring (42) that generates an elastic force for urging the driven side rotor in a direction (Db) opposite from a direction (Da) in which the electromagnet attracts the driven side rotor in a rotational axis direction; and an elastic member (43) that mitigates the impact when the driven side rotor collides with the driving side rotor. Specifically, the driven side rotor has a recessed part (40f) that is recessed in an A direction (Da) and that functions as a pressing part to apply a pressing force to the elastic member by being brought into contact with the elastic member when power is supplied to the electromagnet, the A direction (Da) being a direction opposed to a direction from the driven side rotor set as a start point toward the elastic member in the rotational axis direction, and the elastic member has a to-be-pressed part (43b) that receives the pressing force from the recessed part by being brought into contact with the recessed part when power is supplied to the electromagnet.
