Title:
CLUTCH UNIT
Document Type and Number:
Japanese Patent JP2019039504
Kind Code:
A
Abstract:
To perform a lever operation by using optimum operation torque, and to stabilize the lever operation by suppressing an adverse effect caused by a use environment and secular deterioration.SOLUTION: A clutch unit is composed of a lever-side clutch part 11 for controlling the transmission and blockage of inputted rotation torque, and a brake-side clutch part 12 for transmitting the rotation torque from the lever-side clutch part 11, and blocking the rotation torque which is reversely inputted from an output side. The brake-side clutch part 12 comprises: a side plate 25 which is restricted in rotation; an output shaft 22 from which rotation is outputted; and a brake member which is attached and fixed to the side plate 25, and imparts rotation resistance to the output shaft 22 by using slide torque which is generated by a fitting margin with the output shaft 22. The brake member has a structure in which the rotation resistance imparted to the output shaft 22 is increased and decreased depending on a rotation direction of the rotation torque from the lever-side clutch part 11, and is a coil spring 29 which is contractable and expandable in a diameter with respect to the output shaft 22.SELECTED DRAWING: Figure 1
