徴とするエンジンの主軸受構造。 A cast iron bearing cap, a bearing main bolt inserted from below, and a side bolt inserted from a substantially horizontal direction are tightened and fixed to the skirt portion and bulkhead of an aluminum alloy cylinder block, and the bulkhead and bearing cap are tightened. In a main bearing structure in which a bearing hole is formed to support a crankshaft via a bearing between the bearing caps, a slit is formed in a predetermined portion of the bearing cap located between the outside of the bearing main bolt and the upper side of the side bolt. The main bearing structure of the engine is characterized by the following:
