を連通する排気パイプにおいて、外側パイプと、
同外側パイプ内にその軸線に沿つて挿入され前記
外側パイプより熱膨張率の大きい材質で形成され
た内側パイプとを有し、排気ガス温度が低いとき
には、前記内側パイプと前記外側パイプとの間に
隙間が形成され、排気ガス温度が高いときには、
前記内側パイプが前記外側パイプに当接する様に
構成されたことを特徴とする排気パイプ。 In the exhaust pipe that communicates the exhaust manifold and the catalytic converter, an outer pipe;
an inner pipe inserted along the axis of the outer pipe and formed of a material having a higher coefficient of thermal expansion than the outer pipe, and when the exhaust gas temperature is low, there is a gap between the inner pipe and the outer pipe. When a gap is formed and the exhaust gas temperature is high,
