PROBLEM TO BE SOLVED: To simply fix a roller shaft to the support wall of a cam follower body without specially using a caulking arrangement and to smoothly slide a valve working pattern-varying selector pin inside the roller shaft in a cam flower with a roller in a valve system for an internal combustion engine. SOLUTION: An inner periphery of a through-hole 9b of a support wall Wb on one side is provided with a first groove g1 extending in a peripheral direction, and the outer periphery of one end 7b of a roller shaft 7 is provided with the second groove g2 corresponding to the first groove g1, and C-shaped elastic stoppers L to spanningly engage the insides of both the grooves g1, g2 are attached to the first and a second groove g1, g2 so as to control axial relative movement between the roller shaft 7 and the support walls Wa, Wb, and a selector pin P is slidably fitted in the inner periphery of the roller shaft 7 of an adjacent cam follower.
