Ｖ型エンジンのクランク軸支持構造。A crankshaft support structure for a V-type engine, in which a lower block having a plurality of integrally formed bearing cap parts is bolted to the lower end of the cylinder block of a V-type engine, and the crankshaft is supported by the lower block and cylinder block. , the cylinder block and the lower block are located on the outside of the bearing cap portion on one side of the crankshaft, which is the left side of the crankshaft when viewed from the direction of the crankshaft so that the direction of rotation of the crankshaft is clockwise. The V-shape is characterized in that female threads with the same center and diameter are formed on both the cylinder block and the lower block with the abutting surfaces in between, and a fastening bolt is screwed together across both female threads. Engine crankshaft support structure.
