Abstract
A cylinder block including an upper block, a crankshaft and a lower block, has a plurality of bearing caps secured to the upper block so as to support the crankshaft for rotation. A generally rectangularly-shaped lower block casing is provided with a first reinforcing rib, located below each bearing cap and extending upright so as to connect opposite side walls of the casing, and a second reinforcing rib, extending from a fitting bracket. A transmission casing is fitted to the cylinder block through the fitting bracket. The second reinforcing rib terminates approximately below one of the bearing caps. The first reinforcing rib associated with the one of the bearing caps is separated from the bearing caps. The first reinforcing ribs are provided with structural stiffnesses such that a first reinforcing rib which is farther away from the one of the bearing caps than another first reinforcing rib has a lower structural stiffness than the other first reinforcing rib.
