Abstract
An object of the present invention is to provide a cam and a one-way cam clutch that realize a reduction in weight and production cost, provide more design freedom in setting the center of gravity of the cam, and achieve high responsiveness. The above object is achieved by a cam configured to make contact with an inner race and an outer race by a rotational moment applied in an engaged direction by an annular spring, in which a plurality of cam plates having an identical outer contour and arranged in parallel along a direction of the pivot axis are coupled together and united by a connecting pin extending in the direction of the pivot axis, and the annular spring is configured to be mountable between adjacent cam plates and/or on an outer side of the plurality of cam plates in the direction of the pivot axis.
