を特徴とする内燃機関の動弁系構造。A cam, a valve that opens and closes the port, a lifter that is always engaged with the valve and has a protrusion on the opposite side of the valve, and the cam handle and is disposed between the cam and the cam handle, and is swingably supported by the shaft. an arm member that is movable along the shaft and has a retaining part that can engage with the protrusion and a space that does not engage with the protrusion; and a biasing means that keeps the arm member in constant contact with the cam. , the arm member,
a moving means for selectively switching and displacing along the shaft between a position where the protrusion of the lifter engages with the engaging portion and a position where the protrusion of the lifter matches the space; When the protrusion of the lifter engages with the engaging portion, the valve is driven to open and close via the arm member, and when the protrusion of the lifter is included in the space, the valve is driven by the swing of the arm member. A valve train structure for an internal combustion engine that is characterized by the fact that no motion is transmitted and the engine stops.
