Title:
REVERSE INPUT PREVENTION CLUTCH AND ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2018/066652
Kind Code:
A1
Abstract:
A reverse input prevention clutch is configured by combining: a reverse input prevention mechanism (1) in which, when an outer ring (5) arranged on the outside in the radial direction of an output shaft (output-side member) (4) of a reverse input prevention clutch is in an arrested state in which rotation is impossible, the rotation of an input shaft (input-side member) (3) is transmitted to the output shaft 4, and the output shaft (4) is locked to an outer ring (5) with respect to reverse input torque applied to the output shaft (4), thereby preventing rotation of the output shaft (4); and an operation control mechanism (2) which, when not in operation, arrests the outer ring (5) of the reverse input prevention mechanism (1) so as to be incapable of rotation, and when manually operated, releases the outer ring (5) so as to be able to rotate freely. Thus, if the operation control mechanism (2) is not operated the output shaft (4) can be rendered incapable of rotation with respect to reverse input torque, and merely by manually operating the operation control mechanism (2) the state can be switched to a state in which the output shaft (4) is allowed to rotate with respect to reverse input torque.
