ABSTRACT:
In an overhead cam type internal combustion engine having a cylinder block extended at an angle to either side of a crankshaft, a first cylinder head is mounted on one side of the cylinder block and a second cylinder head is mounted on the other side of the cylinder block. Each of the first and second cylinder heads includes at least one camshaft for opening and closing intake and exhaust valves. A camshaft driving mechanism comprises a first driving force transmitting means interlocked with the camshaft of the first cylinder head and the crankshaft so as to drive the camshaft thereof, an idler shaft provided at such a position as to equalize the elongation of the first driving force transmitting means with that of the second driving force transmitting means and driven by the first driving force transmitting means, and a second driving force transmitting means interlocked with the idler shaft and the camshaft of the second cylinder head so as to drive the camshaft thereof, whereby the length of the driving force transmitting means can be shortened and the elongation thereof can be reduced. Further, the rotational angular deviation between the camshafts on both sides can be minimized.
