Abstract
A cylinder block includes a water jacket surrounding a cylinder of an internal combustion engine and a water jacket spacer disposed inside the water jacket. In the cylinder block, a direction toward a center of the cylinder in a radial direction of the cylinder is defined as an inner side. A direction away from the center in the radial direction of the cylinder is defined as an outer side. The water jacket spacer includes a spacer plate and a conversion portion protruding from the spacer plate in the radial direction. The conversion portion has an action surface on which a pressure of coolant flowing through the water jacket acts. The conversion portion converts a force applied to the action surface by the pressure of the coolant into a force pushing the spacer plate toward the inner side.
