Title:
ROTATION TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/059358
Kind Code:
A1
Abstract:
The present invention adopts a rotation transmission device in which one end portion of a separation spring (24) is supported by being contacted with a suction surface of an armature (21) with a rotor (22), and the other end portion close to the rotor (22) is supported by a fixing ring (33) inserted into an engagement groove (31) of a small diameter shaft portion of an inner ring (2). Since the inner ring (2) and the armature (21) rotate integrally upon cutting off electricity to an electromagnetic clutch, a rotational difference does not occur between members supporting both ends of the separation spring (24). Therefore, wear due to the rotational difference does not occur in the separation spring (24), unlike the case in which the end portion on one side of the separation spring (24) is supported by being contacted with the rotor (22).
