CLUTCH UNIT
Document Type and Number:
Japanese Patent JP2018119647
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent occurrence of noise or minute vibration at a brake side clutch part due to leakage of lubricant or intrusion of foreign matter.SOLUTION: A clutch unit comprises a lever side clutch part 11 configured to control transmission/blockage of input rotational torque, and a brake side clutch part 12 configured to transmit the rotational torque from the lever side clutch part 11 to an output side and block rotational torque reversely input from the output side. The brake side clutch part 12 includes: a side plate 25 where rotation is constrained; an output shaft 22 to which rotation is output; and a friction ring 29 attached and fixed to the side plate 25, and configured to impart rotational resistance to the output shaft 22 with sliding torque, which is generated by a fitting margin with the output shaft 22. The fitting margin is provided between an inner peripheral surface 29b of the friction ring 29 and an outer peripheral surface 22c of the output shaft 22.SELECTED DRAWING: Figure 1
