ABSTRACT:
A structure for connecting ends of exhaust pipes is disclosed. The structure for connecting is constituted by an annular elastic sealing member with heat resistance which is interposed between two overlapping surfaces of two cylinders in a temporally compressed manner, outwardly-projecting annular projection means each of which is disposed on the surfaces of the cylinders at the portions which do not overlap each other, a first coil spring member which is disposed at an adjustable interval above the surface of the cylinder, and two ends of which are secured to the annular projection means, a second coil spring member two ends of which are secured to two final coils of the first coil spring respectively, and which is disposed over the outer portion of the first coil spring in such a manner that the coil wire of the second coil spring is alternately disposed between the coil wire of the first coil spring.
