Means of Solution: Valve camshafts (26i, 26e) are provided at crankcase portions (2L, 2R) for supporting a crankshaft(1), of left and right cylinder banks(CB1, CB2) disposed on opposite sides of the crankshaft(1). Intake and exhaust valves (14, 15)provided at cylinder heads (4L, 4R) are opened and closed by pull rods (20i, 20e) operated by the valve camshafts (26i, 26e). <IMAGE>
