Abstract
In a valve-moving apparatus for an internal combustion engine, lever members are integrally formed with rocker shaft parts and arm parts, the lever members are provided with large-diameter parts larger in diameter than support parts, disposed between support parts of the rocker shaft parts supported by support members of the engine and the arm parts; rocker arms driven by cams are rotatably supported on the large-diameter parts; and change-over mechanisms for selectively engaging the large-diameter parts and the rocker arms are disposed in the large-diameter parts, thereby improving rigidity of the large-diameter parts and achieving improved reliability of the change-over mechanisms.
