The vertical rib extends vertically between upper and lower deck portions of the cylinder block, and the lateral rib is constructed to constitute a raised ridge of a front one of jacket bottom wall. Alternatively, the reinforcing structure comprises a raised bolt boss that is integrally formed on a front one of jacket bottom walls to catch a connecting bolt used for securing a middle portion of a front cover to the front wall.
