Abstract
A cylinder block includes an inner block member having a cylinder liner portion and an outer block member having a cylinder outer wall portion. With the inner and outer block members assembled together, a water jacket is defined between the outer and inner circumferential surface. A first sealing surface of the cylinder liner portion is opposed to a second sealing surface of the cylinder outer wall portion below the water jacket, and a liquid gasket is provided between the first and second sealing surfaces. A continuous projection is provided on the first sealing surface. When the cylinder liner portion is inserted into the space defined by the cylinder outer wall portion, the projection prevents the gasket from being displaced to a trailing side on the cylinder liner portion with respect to the inserting direction. As a result, the clearance between the block members is sealed reliably.
