ABSTRACT:
To provide an exhaust pipe joint structure which positively absorb vibrations from an internal combustion engine without any leakage or the like and in addition may prevent an enlargement of a system, the joint is connected to the internal combustion engine. When a plurality of first exhaust pipes 2a and 2b juxtaposed to each other is to be connected through a joint 3 to a plurality of second exhaust pipes 4a and 4b juxtaposed to each other, joints 3 having spherical flanges are provided for two or more joint pairs so that a line (V) connecting spherical surface centers of the respective spherical flanges of the respective joint pairs is substantially in parallel with a roll axis (A) of the internal combustion engine. Thus, the shift around the roll axis may be absorbed by a bend of the joint.
