Abstract
A pulley unit capable of ensuring long-term operational stability in use as a one-way clutch is provided. A one-way clutch is disposed between a pulley and its concentric shaft. The one-way clutch exhibits a U-shaped inner ring that is integral with the pulley, a U-shaped outer ring integral with the shaft, and rollers accommodated within wedge-like spaces formed between the inner ring and the outer ring. A load from a belt is exerted not on the one-way clutch but mainly on a bearing disposed radially inside of the one-way clutch.
