As a result, even if the air bleeding valve 10 is always open during the operation of the engine, the pressure difference (P R > P 0 ) as described above causes the air accumulated in the upper portion of the cooling water return water chamber 5 to be air. It is guided to the cooling water outlet pipe 9 through the vent valve 10 and the air vent pipe 11.
