Abstract
A cam follower includes a roller on which a cam rolls. A material ratio Rmr (C) (C: a section level %) of an radially outer surface of the roller is set to relations of 0%<Rmr (10%)≦10%, a Kurtosis Rku of a roughness profile of the outer surface is set to 4≦Rku≦10, an arithmetic mean roughness Ra of the outer surface is set to 0<Ra≦0.15, and a compression stress S of the outer surface is set to 800 MPa≦S≦1,100 MPa.
