Abstract
In an engine block structure in a multi-cylinder engine in which a piston is incorporated from the side of a crank chamber into each of a plurality of cylinders disposed in series in a cylinder block, cylinder axes of the two adjacent cylinders are disposed to extend in such directions that they are gradually spaced apart from each other as proceeding from the side of a valve operating chamber toward the crank chamber as viewed from a direction of arrangement of the cylinders. Thus, a sufficient crankshaft bearing area can be ensured without bringing an increase in number of parts and an increase in size of the engine block.
