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.
