摘要： PROBLEM TO BE SOLVED: To provide a flow passage forming member for reducing the number of part items, by reducing a space around an engine, in the flow passage forming member fastened to an engine body.
SOLUTION: This flow passage forming member 50 is formed with a cooling water flow passage 24 joined to a body side cooling water flow passage 22 with a cooling water joining opening 23, and an engine oil flow passage 34 joined to a body side engine oil flow passage 32 with an engine oil joining opening 33. A fastening boss hole 43 to a cylinder block 3 is arranged so that the center of gravity Pw of the cooling water joining opening 23 and the center of gravity Po of the engine oil joining opening 33, are positioned inside a square shape L formed by connecting the center of the respective fastening boss holes 43 by a straight line. The center of the respective fastening boss holes 43 is not positioned in an area R formed by connecting the outer edge of the cooling water joining opening 23 and the outer edge of the engine oil joining opening 33 by a tangent.
