徴とする内燃機関の弁強制開閉装置。 In an internal combustion engine having at least two intake valves or exhaust valves for one cylinder, a valve-opening cam is provided on the camshaft and positioned above the two valves to push open each valve, and A single valve-closing cam is provided between the cams and pulls up each valve, while a valve forcing driver connected to the two valves is provided, and the valve forcing driver is used to close the valve through its bridge. A lifter suspended from the valve opening cam and arranged on the valve force driving body so as to come into contact with the valve shaft of each valve is brought into contact with the valve opening cam, and one side of the valve force driving body parallel to the camshaft is brought into contact with the valve opening cam. A valve forced opening/closing device for an internal combustion engine, characterized in that the valve is brought into sliding contact with a guide wall of a cylinder head, and the other side opposite to this one side is also brought into sliding contact with a guide wall of a rocker cover attached to the cylinder head.
