Abstract
In a water-cooled engine cylinder block, a lower end of a water jacket outer wall and a cylinder wall are joined by a water jacket base wall, and coolant is led into a space formed by the cylinder wall, water jacket base wall and water jacket outer wall. A bend part having a crank shape cross-section is formed in the water jacket base wall. As a result, the rigidity of the water jacket base wall decreases so that transmission of the axial tension of the head bolt to the cylinder wall is suppressed, and deformation of the cylinder wall is suppressed.
