ABSTRACT:
In a balancer apparatus of an engine having an oil pump, a space on a chain side and a space on an oil strainer side are partitioned by a projecting portion projecting in a direction which perpendicularly crosses balancer shafts in a balancer housing formed on an oil pump housing. An oil strainer is attached to a side wall on the anti-chain side of the projecting portion, and a chain tensioner for applying tension to a chain is arranged in the space on the chain side formed by enlarging the attaching surface of the oil pan outwardly so as to enclose the projecting portion. Thus oil which has been stirred by the chain and in which air has been mixed is prevented from being sucked into the oil strainer.
