とを特徴とする内燃機関の動弁機構。 A push rod is pushed up and reciprocated by the rotation of the camshaft via a roller tappet that contacts the camshaft, a rocker arm whose one end is pushed by the push rod and rotates around the shaft placed at a predetermined position on the cylinder head, and a rocker arm attached to the cylinder head by a spring. In a valve operating mechanism for an internal combustion engine comprising intake and exhaust valves that are mounted in a biasing manner and are opened and closed by a pushing force periodically applied from the other end of the rocker arm to the valve stem end, a recessed portion is provided in the upper part of the roller tappet. A spherical receiving portion having a recessed portion for contacting the spherical end of the push rod is fitted into the recessed portion, and a gap formed between the inner wall and bottom surface of the recessed portion and the spherical receiving portion is sealed with silicone oil. A valve train for an internal combustion engine characterized by:
