Provided is a cam follower apparatus that has excellent durability, assembly characteristics and freedom of design, and together with being able to reduce the size and weight, is able to reduce the manufacturing cost. Both end sections of a support shaft 3a are inserted into support holes 15b, 15c in support wall sections 12b, 12c, and the support shaft 3a is supported by the support wall sections 12b, 12c such that relative rotation is possible. An inner ring 16, having an outer diameter D 16 that is greater then the inner diameter d 15 of the support holes 15b, 15c, is fitted around the outer circumferential surface of the middle section in the axial direction of the support shaft 9a so as to be able to rotate together with the support shaft 9a Moreover, a plurality of cylindrical rollers 13 are arranged between an inner-ring raceway 17, which is formed around the outer circumferential surface of the inner ring 16, and an outer-ring raceway 18, which is formed around the inner circumferential surface of a tappet roller 8b that is provided on the outer-diameter side of the inner ring, so as to be able to roll freely. |
