<P>PROBLEM TO BE SOLVED: To provide a valve train varying the amount of variation in the valve opening timing of a valve. Ž<P>SOLUTION: This valve train 10 for an internal combustion engine includes: a drive shaft 11; a drive cam 112 provided for the drive shaft 11; a link arm 12 relatively rotatably fitted around the periphery of the drive cam 112; a crank-shaped control shaft 13 having a main shaft portion 131 and an eccentric cam portion 132; a rocker arm 14 rotatably mounted on the eccentric cam portion 132 and rocked by the link arm 12; and a rocking cam 16 coupled to the rocker arm 14 through a link rod 15 and push-pressing the valve. The control shaft 13 has an eccentricity changing means 41 for changing the eccentricity of the eccentric cam portion 132 with respect to the main shaft portion 131. Thereby, according as the eccentricity of the eccentric cam portion 132 with respect to the main shaft portion 131 is increased, the variation in the valve opening timing of the valve when changing the valve lift of the valve is reduced.
