    • PROBLEM TO BE SOLVED: To provide an exhaust device of an internal combustion engine capable of reducing weight by suppressing the transmission of vibration to a first muffler and a second muffler from a V-type internal combustion engine by a simple constitution so that the deterioration of the NV (noise and vibration) performance of a vehicle can be prevented. SOLUTION: Ball joints 34, 35 for connecting front pipes 26, 27 and tail pipes 36, 37 of the exhaust device 20 are provided and the ball joints 34, 35 are positioned so that the displacement of main mufflers 38, 39 fluctuating up and down alternately with a roll axis G1 as a center becomes small. The ball joints 34, 35 are positioned at an antinode of a fluctuation mode when the front pipes 26, 27 and the tail pipes 36, 37 fluctuate up and down alternately with a roll axis G.

    • PROBLEM TO BE SOLVED: To provide an exhaust device of a motorcycle that is extremely effective for engine performance and the like by efficient and effective arrangement of an exhaust pipe.
      SOLUTION: The exhaust device includes an exhaust pipe 117 connected to a cylinder head 119 of an engine 115, and a pair of right and left mufflers 120 connected to the exhaust pipe 117 and placed on right and left sides, respectively, of a rear wheel. The exhaust pipe 117 is divided into two pipes behind the cylinder head 119 and also in front of a rear-wheel suspension device 110, and the two pipes are connected to the paired right and left mufflers 120.
