MOUNTING STRUCTURE OF ENGINE COOLING DEVICE

PROBLEM TO BE SOLVED: To provide a mounting structure of an engine cooling device that enables reduction in man-hours for processing fastening holes and reduction in thickness of a pump body.SOLUTION: An engine cooling device 1 includes: a pump cover 10 having a mechanism for sucking and discharging fluid; a pump body 20 to which the pump cover 10 is mounted and that has a first flow passage 22 for supplying fluid to the pump cover 10; and an inlet 30 that is mounted to the pump body 20 and has a second flow passage 32 for causing the fluid to flow in to the first flow passage 22. In the engine cooling device 1, an annular second seal member 6 is mounted on a boundary surface between the pump body 20 and the inlet 30 to surround the outer periphery of the second flow passage 32. The pump cover 10 and the inlet 30 are fixed to the pump body 20 by bolts 2 and nuts 3, sharing a plurality of female screws 21 formed on the pump body 20 on the outer side of a circular ring of the second seal member 6.
