Abstract
To provide a cam clutch unit that is easy to handle before assembly, with its components prevented from lifting or detachment, and that allows production with fewer machining steps and a lower level of difficulty, while also enabling unit thickness reduction. The cam clutch unit of the present invention includes: a plurality of cams arranged between an inner race and an outer race; a cage ring having a plurality of pocket portions that restrict relative circumferential movements of the cams; and an annular spring that biases the cams. The cams have an engagement step adapted to engage with the spring on one axial end face. The cage ring has a plurality of hook portions that restrict an axial movement of the annular spring. The hook portions have a pressing part that allows the spring to press the cams towards the other axial end.
