Claims

[Scope of utility model registration request]

In a ring-shaped backing that is embedded in the gap between a propulsion fume pipe and a steel collar tube with a T-shaped cross section that is fitted and fixed with a gap provided at the outer periphery of the joint part of the propulsion fume pipe, the outer circumference of the ring of the backing is made of the steel. The ring is vulcanized and bonded to the inner periphery of the manufactured collar tube to be fixed integrally, and the inner peripheral surface of the ring that contacts the hume tube is provided with concave grooves formed in the width direction of the ring at equal intervals in the circumferential direction, and is in close contact with the hume tube. A backing for a joint of a propulsion hume pipe, characterized in that a portion thereof is formed into a substantially tapered thick deformed body.
