This is an intake/exhaust port opening/closing device that selectively opens and closes, and is attached to the cylinder head so as to be rotatable about a circular center, and selectively faces the intake and exhaust ports of the combustion chamber during rotation. A disc-shaped opening/closing valve has an opening that selectively disconnects communication between the combustion chamber and the intake passage and exhaust passage, and the tip of the stem protrudes perpendicularly from the rotation center of the opening/closing valve, which can rotate integrally. An engine comprising: a first gear provided therein; and a second gear rotatably provided on a drive shaft that rotates in conjunction with a crankshaft of the engine, meshing with the first gear and rotating the first gear. Opening/closing device for the intake and exhaust ports in the combustion chamber.
