Abstract:
To certainly lock an output shaft even if rotation torque in a normal/reverse direction is alternately, continuously, and reversely inputted to the output shaft.SOLUTION: A clutch unit is composed of a lever side clutch portion 11 which controls the transmission and interception of inputted rotation torque; and a brake side clutch portion 12 which transmits the rotation torque from the lever side clutch portion 11 to an output side and intercepts the rotation torque reverse inputted from the output side. The brake side clutch portion 12 is equipped with an input shaft 15; an output shaft 31 oppositely disposed coaxially to the input shaft 15; an outer ring 33 which rotatably supports the input shaft 15 and the output shaft 31; and an output gear 36 which is disposed between the input shaft 15 and the output shaft 31 so as to move in an axial direction. A recessed/projecting fitting portion 54 capable of meshing in a rotating direction is provided between the output gear 36 and the outer ring 33. The recessed/projecting fitting portion 54 is composed of a tooth portion 56 formed on an axial end surface of the outer ring 33, and a tooth portion 55 formed on an axial end surface of the output gear 36 opposite to the axial end surface of the outer ring 33.SELECTED DRAWING: Figure 1
