<p>PROBLEM TO BE SOLVED: To reduce cost, and to improve the reliability of a cooling device, by preventing cooling water from being discharged together, when air in a surge tank is pressurized and atmosphere-released from a pressure cap.SOLUTION: An engine cooling device includes a water jacket 1a of an engine 1; a radiator 2; and a surge tank 3 positioned on an upper side and separating bubbles included in cooling water. The engine cooling device has a filler neck 35 adhered on an upper surface of the surge tank 3; a pressure cap 10 detachably attached to the filler neck 35, and atmosphere-releasing when air pressure in the surge tank 3 becomes a set value or more; and a baffle plate which has a semi-circular outer peripheral surface, is adhered along an inner peripheral surface of the filler neck, and has a gutter-shaped horizontal cross section.</p> |
