Abstract

A pair of link arms each supported at one end thereof on an engine body for swinging movement about an axis parallel to a rotational axis for a valve-operating cam are connected at the other ends, for relative turning movement about an axis parallel to the rotational axis, directly to a rocker arm having a valve abutment abutting against an engine valve and a cam abutment contacting with the valve-operating cam. At least any one of the link arms is swingably supported at one end thereof on the engine body for continuous movement within a plane perpendicular to a rotational axis for the valve-operating cam. Such an arrangement ensures that a valve-operating system can be constructed compactly, and the opening lift amount of the engine valve can be changed continuously, while ensuring an excellent followability to the valve-operating cam.
