PURPOSE: A de-coupler structure of a coil spring for a vehicle exhaust pipe is provided to improve the joining in an exhaust system for increasing the durability thereof. CONSTITUTION: A de-coupler structure of a coil spring for a vehicle exhaust pipe is mounted between an exhaust manifold(100) and an exhaust pipe(300), and includes a thermal compression coil spring(250) mounted between inner and outer retainers(210,220). A bellows(150) is closed contacting outer diameters of the exhaust manifold and the exhaust pipe, wherein both ends of the bellows are closely contacting the inner and outer retainers. The coil spring has a vibration absorbing section(B) to be compressed and a vibration absorbing section(A) to be extended.
