Abstract
An engine having a lower block made of an aluminum-based material and having a bearing cap mounted therein in a cast-in manner abutting against front and rear sidewalls of a cylinder block of the engine and coupled to the cylinder block by a bolt, and a pump body is coupled to a lower surface of the lower block by bolts. The pump body also serves as a balancer shaft supporting member, and a journal portion of a balancer shaft is supported on the balancer shaft supporting member. Thus, the rigidity of supporting of the balancer shaft on the balancer shaft supporting member can be enhanced without an increase in size of the balancer shaft supporting member of the engine.
