PROBLEM TO BE SOLVED: To improve the vibration absorbing effect, and prevent the generation of noise in the exhaust pipe connecting structure utilizing a spherical joint by eliminating the regulation in the vibrating direction of the exhaust pipe. SOLUTION: In the exhaust pipe connecting structure that an upstream exhaust pipe and a downstream exhaust pipe, of which the inside is divided into two flow passages by a partitioning plate, are connected to each other through a spherical joint, partitioning plates 34-1, 34-2 inside the upstream exhaust pipe 5 are formed so that a tip thereof is projected inward from the connecting side end surface of the downstream exhaust pipe 31, and outline of the tip thereof is formed into a projecting shape. A partitioning plate 33 inside of the downstream exhaust pipe 31 is formed with a tip having a circular recessed outline along the outline of the tip of the partitioning plates 34-1, 34-2, and buffer materials 35, 43 are arranged in each tip of the partitioning plates 34-1, 34-2 and the tip of the partitioning plate 33 so that each tip surface of both the buffer materials 35, 43 slides for contact with each other. A circular outline of each tip of both the buffer materials 35, 43 is positioned on a semi-spherical surface formed by extending a semi-spherical surface of a gasket 40 having the semi-spherical surface.
