。(1) An opening side cam and a closing side cam adjacent to each other in the axial direction are integrated with a rotationally driven camshaft, and a tenth hook arm slidingly contacts the opening side cam and a tenth hook arm slidingly contacting the closing side cam. A 20th lug arm is pivotably supported on a rocker arm shaft parallel to the camshaft, and the first and 20th lug arms are connected to an intake valve or an exhaust valve that is biased in the valve closing direction by a valve spring. In the forced valve opening/closing device for an internal combustion engine in which either one of the valves is connected, the valve spring is formed into a conical coil shape that surrounds the intake valve or the exhaust valve and becomes smaller in diameter in the valve closing direction. Forced valve opening/closing device for internal combustion engines.
