とを特徴とする内燃機関の吸排気バルブ装置。In an intake and exhaust valve device for an internal combustion engine that opens and closes an intake and exhaust valve that is disposed in a cylinder head so as to be movable up and down and that is normally biased in the closing direction by a valve spring, through a valve drive mechanism. A cylindrical support member is provided to guide and support the spring, and the length of the support member is approximately equal to or slightly longer than the length of the valve spring when the valve is closed minus the maximum lift length of the valve. An intake and exhaust valve device for an internal combustion engine characterized by a short shape.
