Disclosed is a valve mechanism for an internal combustion engine that uses a motor to open/close a valve body of each cylinder. The valve mechanism includes a camshaft that is rotated by the motor and equipped with cams for driving the valve body of a plurality of cylinders; control means that drives the motor while making a mode switch between a normal rotation drive mode in which the camshaft is continuously rotated in one direction to drive the valve body and a swing drive mode in which the camshaft is swung to drive the valve body; and change means that changes the relative angular positions of cylinder-specific cams on the camshaft.
