ンジンのバルブ駆動構造。 An intake valve or an exhaust valve whose one end is a pivot part that is swingably supported by a fulcrum member, and whose other end is normally biased in the valve-closing direction by the spring force of a valve spring transmitted via a spring receiver. In an engine equipped with a rocker arm, which is a valve stem abutting part that abuts the upper end of the valve stem, and a roller that abuts a cam is attached at an intermediate position between the pivot part and the valve stem abutting part, A stem contact portion is provided to protrude upward from the spring receiver and overlaps the roller in the valve lift direction, and further, the spring receiver and the roller overlap each other in a direction perpendicular to the valve lift direction. The valve drive structure of the engine is characterized by:
