PURPOSE: A valve train for an internal combustion engine is provided to prevent the displacement force of the switching element from acting in the axial direction of the valve lifter shaft, thereby reducing abnormal twist and deformation of the valve lifter. CONSTITUTION: A valve train for an internal combustion engine comprises a main valve lifter which rotates around a valve lifter shaft(2) in a rotational direction(D) by a first cam of a cam shaft, and a switching valve lifter(20) which rotates around the valve lifter shaft by a second cam(21) of the cam shaft. The switching valve lifter comprises a switching element with a switching pin(31) and a stopper(32). The stopper is arranged in the main valve lifter or the switching valve lifter. The switching pin is guided to slide in the progress direction from the main valve lifter or the switching valve lifter, where the progress direction is vertical to the valve lifter shaft. |
