The muffler 49 includes a stopper 651 shown in FIG. When the muffler 49 is rotated to the lower right (arrow b direction) from the position shown in FIG. 8 to the position shown in FIG. 9 with the rear collecting pipe 45 as an axis, the lower part (bearing portion 627) of the vehicle body frame 11 and the arrow c in FIG. The stopper 651 moving in the direction comes into contact. That is, when the muffler 49 rotates to the lower right with the rear collecting pipe 45 as a rotation center, a space 653 is formed between the vehicle body and the muffler 49. The space 653 contributes to the replacement work space for the rear wheel 47.
