PURPOSE: To simplify the driving structure of a cam shaft and an oil pump, by driving an connecting together the gear on a crankshaft for taking out a rotational power, reduction gears disposed on respective banks and a drive gear coaxially disposed with the respective reduction gears by a timing belt and a chain, respectively.
CONSTITUTION: When cylinder blocks at the right hand and the left hand are disposed at a prescribed angle on the upper portion of a cylinder block 2 for constructing banks 1A, 1B, a gear 10 for taking out a rotational power is disposed on a crankshaft 6. Reduction gears 11, 11 for both the banks 1A, 1B are disposed at the right and left hands above the crankshaft 6 and drive gears 13 are disposed at the extreme ends of the shaft members of the respective reduction gears 11. A timing belt member 16 trained around the gears 13 are also trained around the cam pulley at the end of a cam shaft 5 and a chain 15 is trained around a drive gear 23 provided with the pump shaft 22 of an oil pump 8 disposed below the crankshaft 6 and the above gears 10, 11.
