を特徴とする二重管のシール構造。 In a double-pipe seal structure in which an annular seal member is fixed to the inner circumferential wall of the outer tube and an inner tube is inserted into the outer tube to seal the gap between the inner tube and the outer tube, the outer diameter of the inner tube is set to D. The amount of eccentricity between the inner tube and the outer tube is δ
And if the inner diameter of the support plate is d1 ,
An annular support plate satisfying d1 <D-2δ is provided on the inner circumferential wall of the outer tube, and an annular rubber plate having an inner diameter smaller than the inner diameter of the support plate is superimposed and provided on the upper surface of the support plate. A double tube seal structure, characterized in that the support plate and the rubber plate are fixed to the lower wall surface of the outer tube.
