Crankshaft lubricating oil passage structure for V-type engine

A crankshaft lubricating oil passage structure of a V-shaped engine that supplies lubricating oil to a bearing portion of a crankshaft provided in a cylinder block or a crankcase, the V-shaped engine including a pair of banks, the pair of banks including cylinders and disposed in a V shape with respect to the crankshaft, a V bank angle as an included angle of the cylinders of the respective banks being set at a narrow angle, the crankshaft lubricating oil passage structure comprising:

• a main oil passage provided between the pair of banks in the cylinder block or the crankcase;
• and
• a sub oil passage extending from the main oil passage to the bearing portion of the crankshaft and guiding the lubricating oil to the bearing portion,
• wherein the main oil passage is formed by connecting divided passage portions that are divided partway in an axial direction by an oil passage connection member that is a separate member from the cylinder block or the crankcase, and
• wherein the sub oil passage is formed by using a pipe member that is a separate member from the cylinder block or the crankcase.
