PURPOSE: An exhaust gas re-circulation device is provided to enhance durability of a re-circulation pipe and to reduce noise and vibration, by changing support structure of a pipe bracket for the re-circulation pipe to minimize exciting force of an engine transmitted to the re-circulation pipe through a pipe bracket and to induce self-damping by the pipe bracket. CONSTITUTION: An exhaust gas re-circulation device comprises a re-circulation pipe(50) connecting a suction pipe and an exhaust pipe of an engine and re-circulating some of exhaust gas exhausted through the exhaust pipe to the suction pipe, and a pipe bracket(60) installed to a body side of the engine to support the re-circulation pipe. The pipe bracket comprises a fastening part(61) mounted to the body side of the engine; a pipe insertion part(65) surrounding the re-circulation pipe; and a connection part(63) connecting the fastening and the pipe insertion part. The inside of the pipe insertion part has point contact or line contact with the re-circulation pipe. Plural embossed portions are protruded on the inside of the pipe insertion part to support the re-circulation pipe through point contact with the re-circulation pipe.
