A first swing arm of each cylinder is swung by a fixed cam of an intake camshaft, so as to operate a first intake valve according to a profile thereof. A second swing arm is swung by a second cam and its swing range is changed by a variable mechanism. Hereby, a lift amount of a second intake valve changes continuously. The second cam is selected from a plurality of cams on a cam piece provided around the intake camshaft.
