Abstract:
1. A divided type cylinder block comprising: an inner block member having a cylinder liner portion defining a cylinder bore, the cylinder liner portion including an outer circumferential surface and a first sealing surface formed at a predetermined position of the outer circumferential surface; an outer block member having a cylinder outer wall portion, the cylinder outer wall portion including an inner circumferential surface and a second sealing surface formed at a predetermined position of the inner circumferential surface, wherein the inner block member is assembled with the outer block member by inserting the cylinder liner portion into the space defined by the cylinder outer wall portion along a predetermined inserting direction, and wherein, with the inner and outer block members assembled together, a water jacket is defined between the outer circumferential surface and the inner circumferential surface and the first sealing surface is opposed to the second sealing surface below the water jacket; a liquid gasket provided between the opposed first and second sealing surfaces; and a restricting portion formed in the first sealing surface, wherein, when the cylinder liner portion is inserted into the space defined by the cylinder outer wall portion, the restricting portion prevents the gasket from being displaced to a trailing side on the cylinder liner portion with respect to the inserting direction, wherein the restricting portion includes a slanted surface slanted with respect to the inserting direction of the cylinder liner portion.
