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.
