Abstract
A valve control mechanism is configured that is capable of optimally controlling an engine by lifting an intake valve only by the necessary amount, while suppressing noise at the time of operation. This valve control mechanism includes a control member that rotates around a control axis due to a driving force of an actuator, and a base end portion of a rocker arm is pivotably supported around a pivot axis by an eccentric support portion of the control member. The rocker arm is pivoted by a cam portion of a camshaft abutting against an intermediate roller of the rocker arm, and an operation of opening the intake valve is performed due to a pressure force from the pivot end. The rocker arm is shifted in the longitudinal direction due to an operation of the actuator, and control for changing the lift amount of the intake valve is performed.
