Abstract
Providing a pulley unit with a reduced diameter, stable operating characteristics, and that is simple and readily removable from an engine is accomplished by a one-way clutch disposed between a pulley and a shaft body that are concentrically arranged. A shaft defines a shaft attachment space at a position which is not overlapped by rollers contained in the one-way clutch in an axial direction. The shaft body is attached to the shaft at the shaft attachment space. The shaft body, disposed inside the rollers in a radial direction, does not have a through hole, but rather, has a non-through structure.
