A decoupler of an exhaust pipe having spaces for absorbing various stresses caused by impact, vibration, heat distortion, or the like. The decoupler includes a corrugated bellows repeatedly formed with corrugations, a sleeve for protecting the bellows against exhaust gas, an outer cap for enclosing the outer side of one end of the bellows, an inner cap for enclosing the outside of the bellows, and wire mesh buffering members installed in spaces defined by the inner cap and the outer cap, to support the inner cap and the outer cap and to maintain air tightness between the inner cap and the outer cap. The outer cap has bending portions formed at the ends thereof, so as to maintain a gap between the outer surface of the inner cap and the end of the outer cap. The surfaces of the buffering members are closely attached to the outer surface of the inner cap, upper inside surfaces of the bending portions and lateral inner surfaces of the bending portions, so as to define buffering spaces between the buffering members and the bending portions. Thus, the deformation of the decoupler can be prevented so as to reduce wearing of the decoupler and frictional noise and to enhance the durability of the decoupler. |
