Claims (1)
内側に配置された内筒とを具え、前記内筒の内部
空間を排気ガスが通過するようになつた排気管伸
縮継手において、前記金属ベローズと前記内筒と
の間に形成される環状空間に、前記排気ガスの圧
力よりやや高い圧力の空気を供給するようにした
ことを特徴とする排気管伸縮継手。 In an exhaust pipe expansion joint comprising a bellows-shaped metal bellows and an inner cylinder disposed inside the metal bellows, the exhaust pipe expansion joint allows exhaust gas to pass through an internal space of the inner cylinder. An exhaust pipe expansion joint characterized in that air having a pressure slightly higher than the pressure of the exhaust gas is supplied to an annular space formed between the exhaust pipe and the cylinder.
