Abstract: A clutch unit used for a vehicle seat includes an input side clutch configured such that one member of an input side inner ring member and an input side outer ring member rotates with a rotation of an operation lever, and the other member is rotated via an input side transmission member, so that a rotation of the operation lever is transmitted to an output side clutch. A rotation suppressing member configured to apply a rotational resistance force greater than a force for the co-rotating is provided between the other member and a member that does not rotate during a return operation of the operation lever, so as to suppress co-rotation of the other member by the one member during the return operation to the neutral position.
