PROBLEM TO BE SOLVED: To provide an exhaust gas pipe that can effectively cool not only exhaust gas in the pipe periphery region but also exhaust gas in the pipe center region. SOLUTION: The exhaust gas pipe comprises a pipe body 1 and a partitioning part 2 that partitions the hollow of the pipe body 1 into a plurality of sections in the axial view. The periphery of the pipe body 1 has heat radiating fins 3 extending along the junctions between the pipe body 1 and the partitioning part 2 to thus efficiently diffuse the heat of exhaust gas that the partitioning part absorbs. |
