PURPOSE: Continuously variable transmission device is installed between a crank shaft and an oil pump, to rotate the oil pump in a constant speed even though the rpm of the engine changes. CONSTITUTION: An oil pump driving device comprises a driving pulley connected to a crank shaft(2) to rotate together. A driven pulley(6) is installed in a rotation shaft(10) of the oil pump(8). A belt(12) is connected between the driving pulley and the driven pulley to transfer rotation force of the crank shaft to the rotation shaft of the oil pump. An operation portion varies diameters of the driving pulley and the driven pulley by engine rpm.
