## Abstract

The vehicle of the present application includes a vehicle frame; a muffler supported by the vehicle frame; and a supporting unit comprising a rubber damper, located between the muffler and the vehicle frame and, connected to the vehicle frame such that the muffler is suspended from the vehicle frame and supported by the vehicle frame. The supporting unit comprises a first bracket and a second bracket on the first bracket.

## Claims

### Claim 1

A vehicle comprising:
a vehicle frame; a muffler supported by the vehicle frame; and a supporting unit comprising a rubber damper, located between the muffler and the vehicle frame and, connected to the vehicle frame such that the muffler is suspended from the vehicle frame and supported by the vehicle frame,
wherein:
the supporting unit comprises a first bracket and a second bracket on the first bracket;
the first bracket comprises a first body distant from an outer surface of the muffler and a first attachment attached to an outer surface of the muffler, and extending along a first axis from the first body on the outer surface of the muffler; and
the second bracket comprises a second body distant from the first bracket and a holder on the second body, configured to hold the rubber damper and connected to the vehicle frame via the rubber damper, and a second attachment attached to the first attachment of the first bracket, and extending from the second body;
wherein the first attachment comprises: a first sub-attachment, a second sub-attachment and a third sub-attachment,
wherein the second attachment comprises: a fourth sub-attachment, a fifth sub-attachment and a sixth sub-attachment,
wherein the first sub-attachment is positioned in between the fourth sub-attachment and the fifth sub-attachment in a second axis along the outer surface and crossing the first axis.

### Claim 2 (depends on 1)

The vehicle of claim 1, wherein the second sub-attachment and the third sub-attachment are disposed on a different position on the second axis.

### Claim 3 (depends on 1)

The vehicle of claim 1, wherein at least one of the fourth sub-attachment, the fifth sub-attachment or the sixth sub-attachment extends toward one direction along the first axis while a different one of the fourth sub-attachment, the fifth sub-attachment or the sixth sub-attachment extends toward an opposite direction.

### Claim 4 (depends on 3)

The vehicle of claim 3, wherein the second sub-attachment and the third sub-attachment are disposed on a different position on the second axis.

### Claim 5 (depends on 1)

The vehicle of claim 1, wherein:
the first attachment comprises a first sub-attachment, a second sub-attachment and a third sub-attachment; the second attachment comprises a fourth sub-attachment, a fifth sub-attachment and a sixth sub-attachment;
one of the first, second or third sub-attachments extends toward one direction along the first axis from the first body while another of the first, second or third sub-attachments extends toward an opposite direction from the first body;
one of the fourth, fifth or sixth sub-attachments of the second attachment extends toward one direction along the first axis from the second body while another of fourth, fifth or sixth sub-attachments extends toward the opposite direction from the second body;
each sub-attachments of the first attachment is disposed on a different position on the second axis;
each sub-attachments of the second attachment is disposed on a different position on the second axis;
a position of one of the first, second or third sub-attachments of the first attachment coincides with a position of one of the fourth, fifth of sixth sub-attachments of the second attachment on the second axis;
the one of the first, second or third sub-attachments of the first attachment extends toward one direction along the first axis while the one of the fourth, fifth of sixth sub-attachments of the second attachment extends toward the opposite direction along the first axis;
a position of the other of the first, second or third sub-attachments of the first attachment coincides with a position of the other of the fourth, fifth of sixth sub-attachments of the second attachment on the second axis; and
the other of the first, second or third sub-attachments of the first attachment extends toward one direction along the first axis while the other of the fourth, fifth of sixth sub-attachments of the second attachment extends toward the opposite direction along the first axis.

### Claim 6 (depends on 1)
