ABSTRACT:
An engine balancer system is provided in which a balancer housing (17) disposed so as to face an oil pan beneath a crankshaft is formed by joining an upper housing (29) and a lower housing (30) via mating faces (P), and the height of the mating faces (P) is lower on a vehicle front side than on a vehicle rear side. Oil discharge holes (45a, 46) for discharging oil that is within the balancer housing (17) are formed in the mating faces (P) on the higher side of the balancer housing (17) and in the upper housing (29) above the mating faces (P) on the lower side of the balancer housing (17). This enables the position of the oil discharge hole (45a) on the lower side to be as high as possible, thereby suppressing penetration of oil into the interior of the balancer housing (17) through the oil discharge hole (45a).
