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.
