An exhaust pipe structure of an internal combustion engine vehicle is provided, which includes a coupling part coupling a first exhaust pipe to a second exhaust pipe disposed serially. The coupling part includes an insertion pipe part formed in the second exhaust pipe, an outer circumferential pipe part formed in the first exhaust pipe and to which the insertion pipe part is inserted, an inner circumferential pipe inserted into the outer circumferential pipe part, an annular protrusion formed in the second exhaust pipe and protruding radially outward from the entire circumference of the insertion pipe part, and a clamp member coupling the outer circumferential pipe part to the annular protrusion. The clamp member has a band part wrapped radially outside around a part where a flare part of the outer circumferential pipe part overlaps with the annular protrusion, and a tightening part tightening the band part.
