ABSTRACT:
An exhaust pipe decoupler for vehicles including a bellows (10), an outer braid member (20) spaced from the bellows and braided with a predetermined angle, a retainer (30) having a support (31) inwardly curved at both ends thereof for engaging to a ring damper (40), the retainer being affixed to the ends of the bellows (10) and installed between the outer surface of the bellows (10) and the outer braid member (20) to prevent direct contact thereof, the ring damper (40) located outward the support (31) formed in the retainer (30), a fixing cap (50) coupled to the outer diameter of the outer braid member (20) in order that the outer braid member (20) and the retainer (30) are located outward the bellows (10), wherein the outer braid member (20) absorbs tension in excessive outer forces, i.e., displacement of tension and compression, and the ring damper (40) controls the displacement of compression and shear displacement by the ring damper (40), thereby controlling the bellows within the elastic range.
