An object of the present invention is to provide a supporting mechanism that enables an exhaust treatment device to be disposed in a position as low as possible so that rearward visibility may be improved in a work vehicle in which the exhaust treatment device is disposed above the engine. The supporting mechanism according to a first aspect of the present invention supports a first exhaust treatment device and a second exhaust treatment device for treating exhaust gas from an engine, and is provided with a sub-bracket, a base bracket, a first supporting member, and a second supporting member. The base bracket includes a first connecting part, a second connecting part, a first pipe member, and a second pipe member. The sub-bracket supports the first exhaust treatment device and the second exhaust treatment device. The base bracket supports the sub-bracket. The first supporting member and the second supporting member respectively support one side and the other side of the base bracket. The first connecting part and the second connecting part are respectively joined to the first supporting member and the second supporting member. The first pipe member and the second pipe member are installed between the first connecting part and the second connecting part. The sub-bracket is attached to the first pipe member and the second pipe member, extends in the lateral direction of the first pipe member and the second pipe member therefrom, and is separated from the first connecting part and the second connecting part.
