PROBLEM TO BE SOLVED: To facilitate work for installing an internal combustion engines in an automobile or the like, where the engine room is narrow and the optimum arrangement of auxiliary machines for internal combustion engines by miniaturizing internal combustion engines in the axial direction of a crankshaft. SOLUTION: This internal combustion engine is provided with first and second cylinder bodies 9 and 10, where the first and second cylinders 4 and 5 arranged around a crank shaft 3 are projected outward in radial directions from the side of the crank shaft 3 and displaced to each other in the peripheral direction of the crank shaft 3. First and second pistons 13 and 14 are fitted slidably and axially to the cylinder bodies 9 and 10 respectively and first and second connecting rods 15 and 16, which connect the pistons 13 and 14 and the crankshaft 3 in interlocking relation with each other respectively. The small end section 20 of the first connecting rod 15 is pivotally supported on the first piston 13, and the large end section 22 is pivotally supported on the crankshaft 3. The small end section 25 of the second connecting rod 16 is pivotally supported on the second piston 14, and the large end section 27 is pivotally supported the midway of the first connecting rod 15 in its longitudinal direction.
