を特徴とする内燃機関の動弁系構造。A cam, a valve having a valve stem and driven by the cam to open and close a port, a transmission member provided near an end of the valve stem and having a hole through which the valve stem can be inserted, and the transmission member and a shim that is disposed between the cam and the cam and has a hole through which the valve stem can be inserted, and a position where the hole of the transmission member aligns with the valve stem and a position where the hole does not align with the valve stem. and control means for selectively displacing the transmission member, a groove into which the end of the valve stem can fit is formed in the nose of the cam, and the hole in the transmission member is aligned with the valve stem. When not, the movement of the cam is transmitted to the valve stem via the shim and the transmission member to open and close the valve, and when the hole in the transmission member is aligned with the valve stem, the movement of the cam is transmitted to the valve stem via the shim and the transmission member. and a valve train structure for an internal combustion engine, wherein the valve stem is inserted into a hole in the transmission member and a hole in a shim so that the upper valve is not driven to open or close, although the valve stem is transmitted to the transmission member.
