Cam clutch unit

A cam clutch unit comprising a plurality of cams arranged between an inner race and an outer race that are coaxially provided to be capable of relative rotation with respect to each other, a cage ring made of a resin and having a plurality of pocket portions that restrict relative movement of the cams in a circumferential direction, and a biasing member that biases the cams so as to bring the cams into contact with the inner race and the outer race,

• each of the cams being configured to have a body portion placed in the pocket portion while being inserted therethrough, and have a head portion continued to an outer circumferential side of the body portion, and moreover have a leg portion continued to an inner circumferential side of the body portion, with a dimension in an axial direction being smaller than a dimension of the pocket portion in the axial direction,
• each of the head portion and the leg portion being configured such that a maximum cross-sectional width thereof corresponding to a maximum distance between two parallel lines, when each of the head portion and the leg portion is held between the two parallel lines, is larger than an opening width of the pocket portion in a cross section perpendicular to a rotation center of the cam,
• at least one of the head portion and the leg portion being configured to be allowed to pass through the pocket portion by rotating the cam while inserting the cam, which is in an inclined attitude, into the pocket portion along an opening direction of the pocket portion and thereby elastically deforming the pocket portion.
