Document Type and Number:
Japanese Patent JP2019039465
Kind Code:
A
Abstract:
To surely lock an output shaft even if rotation torque in a forward direction is alternately, continuously and reversely inputted to the output shaft.SOLUTION: A clutch unit is composed of a lever-side clutch part 11 for blocking and controlling the transmission of inputted rotation torque, and a brake-side clutch part 12 for transmitting the rotation torque from the lever-side clutch part 11 to an output side, and blocking the rotation torque which is reversely inputted from an output side. The brake-side clutch part 12 comprises: an input shaft 15; an output shaft 31 which is oppositely arranged coaxial with the input shaft 15; an outer ring 33 for rotatably supporting the input shaft 15 and the output shaft 31; and an output gear 36 which is arranged between the input shaft 15 and the output shaft 31 so as to be movable in an axial direction. Irregular fitting parts 54 which can be engaged with each other in a rotation direction are formed between the output gear 36 and the outer ring 33, a cam part for moving the output gear 36 to an axial direction is arranged between the input shaft 15 and the output shaft 36, and the engagement and release of the irregular fitting parts 54 can be controlled by the axial movement of the output gear 36 by the cam part.SELECTED DRAWING: Figure 1
