WIPO Patent Application WO/2010/103813
Kind Code:
A1
Abstract:
Provided is a multilayered tube by which a heat insulation effect and a vibration suppression effect can be obtained, and the structure of an exhaust system using the multilayered tube can be further compacted to a conventional exhaust system. A multilayered tube (1) to be connected to a vibration suppression source when being used is comprised of an inner tube (2); an outer tube (4) coaxially disposed with the inner tube (2) on the outside of the inner tube (2); and a heat insulation and vibration suppression element (3) provided between the inner tube (2) and the outer tube (4).
