PROBLEM TO BE SOLVED: To compactly arrange an exhaust component by securing a necessary exhaust pipe length while concentrating a mass and lowering the center of gravity. SOLUTION: An exhaust port is formed at the back surface of a cylinder 10, and the exhaust upstream end of an exhaust pipe 19 is connected to the exhaust port. The exhaust pipe 19 is bent at a first bent part, a second bent part 19b and a third bent part 19c. The exhaust pipe is firstly bent forward at the first bent part 19a behind a cylinder 10, passes the side surface of the cylinder 10 diagonally forward and downward, is bent downward at the second bent part 19b in front of a crankcase 9, extends downward in front of an oil pan 9a, is bent downward of the oil pan 9a at the third bent part 19c, and connected to a muffler 20 arranged below a transmission.
