ラー9に連結されている。By the way, the unit swing type engine 5 has a forward-inclined cylinder 7 at the front thereof, and an exhaust pipe 8 extends from the cylinder 7. The exhaust pipe 8 extends downward from the cylinder 7, is bent at a substantially right angle, extends outward below the unit swing type engine 5, and is then bent at a substantially right angle again toward the rear of the vehicle body. It extends and is connected to a muffler 9 that is disposed diagonally on the side of the rear wheel 3.
