摘要： A water jacket spacer is inserted into a groove-like coolant passage provided to a cylinder block that is provided to an internal combustion engine, and includes a main body that has a shape that conforms to the groove-like coolant passage, and either or both of an inner wall-side contact member and an outer wall-side contact member, the inner wall-side contact member being disposed on the inner wall side of the main body along the longitudinal direction of the inner wall of the main body, and coming into contact with the cylinder bore-side wall surface of the groove-like coolant passage to divide the groove-like coolant passage situated on the inner side with respect to the water jacket spacer into an upper part and a lower part, and the outer wall-side contact member being disposed on the outer wall side of the main body along the longitudinal direction of the outer wall of the main body, and coming into contact with the outer wall surface of the groove-like coolant passage to divide the groove-like coolant passage situated on the outer side with respect to the water jacket spacer into an upper part and a lower part. An internal combustion engine in which the cylinder bore wall has a uniform temperature can be obtained using the water jacket spacer.
