PROBLEM TO BE SOLVED: To provide a reverse input prevention clutch unit which can coaxially arrange two pieces of reverse input prevention clutches compactly at favorable operability.SOLUTION: When coaxially arranging two pieces of reverse input prevention clutches ( first clutch A and second clutch B), an input shaft 2a which rotates integrally with an input member 1a of the first clutch A penetrates an input member 1b of the second clutch B and an output member 4, both the input members 1a, 1b of both the clutches A, B and the output member 4 adjoin each other in an axial direction, outer rings 7 of both the clutches A, B are fixed to a common fixed member 8, and a reverse input prevention clutch unit can be thereby made compact in size compared with the case that the two pieces of the reverse input prevention clutches having the same structures are aligned in the axial direction, and thus, favorable operability can be obtained.SELECTED DRAWING: Figure 1 |
