Abstract
To provide a cam clutch unit that reduces the number of machining steps and level of difficulty of cam clutch production and reduces rotation resistance caused by rollers. The cam clutch unit includes: a plurality of cams and a plurality of rollers circumferentially arranged between an inner race and an outer race that are coaxial and rotatable relative to each other; a cage ring having a plurality of pocket portions that restrict circumferential relative movements of the cams and the rollers; and an annular spring that biases the cams. The cams each have, on one axial end face, an engagement step that can engage with the spring. The cage ring has a plurality of hook portions that restrict axial movements of the annular spring.
