In order to swing the rocker arm that is swingably supported by the support means, a drive cam that responds to the rotation of the engine is brought into sliding contact with the rocker arm, and is able to open and close the engine body while being biased by a spring in the valve closing direction. A driven cam that is in sliding contact with the rocker arm is interlocked and connected to the head of the supported engine valve, and a biasing force is provided between the engine body and the driven cam that exerts a biasing force in the direction of sliding the driven cam into sliding contact with the rocker arm. In a valve train for an internal combustion engine in which a force means is provided, the drive cam is slidably contacted with the longitudinal middle part of the rocker arm, is movable in the axial direction and is supported by the engine body, and has one end slidably attached to one end of the rocker arm. a support shaft provided with a spherical support portion for contacting and supporting; interlocking with the support shaft to change the axial position of the support shaft;
A valve operating system for an internal combustion engine, characterized in that a supporting means including a driving mechanism connected thereto, and a driven cam are disposed at positions opposite to the driving cam with respect to the rocker arm and corresponding to both ends of the rocker arm.
