PROBLEM TO BE SOLVED: To change a rotational ratio between an engine and a fuel pump without large increase in cost. SOLUTION: In fuel pump drive structure, a crankshaft 2 transmits torque through a gear train 3 to drive the fuel pump 4 by the engine. A plurality of kinds of drive units 7 in which rotational ratio is changed without changing a distance between the centers of an input shaft 8 and an output shaft 9 are selectively interposed between the fuel pump 4 and the gear train 3.
