A tailpipe for a vehicle, which has a tubular body may include a central pipe positioned in the body, and a plurality of sub-pipes which is disposed to surround an outer circumferential surface of the central pipe.
First claim
Opening claim text (preview).
What is claimed is: 1. A tailpipe for a vehicle, which has a tubular body, the tailpipe comprising: a central pipe positioned in the tubular body; and a plurality of sub-pipes disposed to surround an outer circumferential surface of the central pipe, wherein the sub-pipes include portions asymmetrically exposed to an outside of the tubular body of the tailpipe and having different lengths in an axial direction of the central pipe. 2. The tailpipe of claim 1 , wherein a length of the central pipe is shorter than a length of each sub-pipe, and a diameter of the central pipe is greater than a diameter of each sub-pipe. 3. The tailpipe of claim 2 , wherein the central pipe and the sub-pipes are fixed by perpendicularly penetrating a circular plate-shaped fixing plate mounted in the tubular body. 4. The tailpipe of claim 1 , wherein a length of a portion of the central pipe, which is exposed to the outside of the tubular body of the tailpipe, is shorter than the length of the portions of the sub-pipes which are exposed to the outside of the tubular body. 5. The tailpipe of claim 4 , wherein the central pipe and the sub-pipes are fixed by perpendicularly penetrating a circular plate-shaped fixing plate mounted in the tubular body. 6. The tailpipe of claim 1 , wherein the length of the exposed portions of the sub-pipes is gradually increased from a lower side to an upper side of the central pipe. 7. The tailpipe of claim 6 , wherein the central pipe and the sub-pipes are fixed by perpendicularly penetrating a circular plate-shaped fixing plate mounted in the tubular body. 8. The tailpipe of claim 1 , wherein the central pipe and the sub-pipes are fixed by perpendicularly penetrating a circular plate-shaped fixing plate mounted in the tubular body.
