PURPOSE:To prevent the failure of closing of an air-bleeding port cap after filling with cooling water by connecting an air-bleeding port in the upper part of an engine main body to a water-pouring part of a radiator. CONSTITUTION:An air-bleeding port 12 for filling with cooling water is provided on the upper part of an engine main body 1, and connected to a water pouring part of a radiator 3, that is, an opening 15a of a filler neck 15 via a hose 12. The top of the hose 12 is directed upward to face to a seal member 21 of a radiator cap 20. Therefore, when the opening 15a of the water pouring part is closed by the radiator cap 20, the top of the hose 12 connected to the air-bleeding port 12 can be closed at the same time. |
