ことを特徴とするエンジンの動弁装置。 A rocker arm is swingably arranged to straddle the head of a valve that is driven to open and close in the axial direction and the head of a hydraulic latch adjuster that is fitted and fixed in a recess provided on the cylinder head side. In addition, an intermediate portion of the rocker arm is brought into contact with a cam, and the lift displacement of the cam is transmitted to the valve via the rocker arm that swings about the end on the hydraulic lash adjuster side as a fulcrum. In the valve train, a communication port that is open to the atmosphere is formed at the bottom of the recess, and an end of the hydraulic latch adjuster that fits into the convex portion corresponds to the communication port. A valve operating system for an engine, characterized in that a sealing member is provided at a position to oil-tightly close the communication passage when the hydraulic latch adjuster is fitted and fixed in the recess.
