ABSTRACT:
A valve train includes a primary rocker arm50which is oscillated about a primary oscillating center line L4by an inlet cam21, a secondary rocker arm60which transmits a valve drive force F1to an inlet valve14and oscillates about a secondary oscillating center line L5, and a holder30which supports the primary and secondary rocker arms50, 60in such a manner that the primary and secondary oscillating center lines L4, L5rotate together therewith. As the holder30approaches an oscillating position where a valve operating property is obtained where a maximum lift amount becomes maximum, an abutment position P1where a cam lobe portion21babuts with a roller53of the primary rocker arm50approaches a specific straight line L10which passes through a holder oscillating center line L3and a rotational center line L2of the inlet cam21.
