Connecting ribs 4 extending between the passages 1b are protruded at intervals along the longitudinal direction of the passage 2. As shown in FIG. 2, the upper end of the coupling rib 4 has a substantially T-shaped cross section, and a portion of the cooling water flowing through the passage 2 in the direction of arrow a is taken up in the direction of arrow b using its head 4a. It acts as a dam for water. The cooling water taken into the base side of the coupling rib 4 by the above-mentioned weir action is made to flow into the periphery of the cylinders of each bank 1a, 1b through the water inlet 5. As shown in FIG. 3, the water inlet 5 is positioned symmetrically with respect to the passage 2, so that the left and right banks 1a, 1b have a common cylinder head (not shown), and the water inlet 5 is connected to the cylinder head. The cooling water that has flowed into the surrounding water jackets (none of which are shown) is rotated in the left and right banks 1a and 1b so that the directions of rotation are opposite to each other, and then rises inside the water jacket and reaches the cylinder head (none of which is shown in the figure). (not shown) to cool it.
