Abstract
A partition member used in a cylinder block of an internal combustion engine is disclosed. The partition member is arranged in a groove-like cooling passage through which a cooling heat medium flows. The partition member includes a separating wall and a flexible lip member. The separating wall divides the cooling passage into an inner passage and an outer passage. The inner passage is located close to the cylinder bores, and the outer passage is located outside of the inner passage. The lip member extends from the separating wall toward the opening of the cooling passage in such a manner that, when the partition member is arranged in the cooling passage, the lip member contacts one of the inner surfaces of the cylinder block forming the cooling passage. When the partition member is arranged in the cooling passage, the distal edge portion of the flexible lip member contacts the inner surface due to force produced through flexible shape restoration of the lip member.
