周縁部分に２つの環状凹部を設け、内側の環状凹
部内に前記内筒端部を位置させて第１のラビリン
ス構造を形成し、前記内筒の端部側の外周面に配
設した環状のじやま板を外側の環状凹部内に位置
させて第２のラビリンス構造を形成し、さらに、
前記内筒の端部側の内周面に環状のじやま板を配
設したことを特徴とする排気管伸縮継手。 A bellows-shaped metal bellows, an inner cylinder disposed inside the metal bellows, and a flange connected to the metal bellows and having a hole in the center, so that exhaust gas passes through an internal space of the inner cylinder. In the exhaust pipe expansion joint that has become a modern exhaust pipe, two annular recesses are provided at the peripheral edge of the hole of the flange, and the inner cylinder end is positioned within the inner annular recess to form a first labyrinth structure. A second labyrinth structure is formed by positioning an annular diagonal plate disposed on the outer circumferential surface of the end portion of the cylinder within the outer annular recess;
An exhaust pipe expansion joint, characterized in that an annular wall plate is provided on the inner circumferential surface of the end portion of the inner cylinder.
