摘要

A supporting mechanism supports a first and second exhaust treatment devices for treating exhaust gas from an engine and is provided with a base member, a first supporting member, and a second supporting member. The base member includes first and second connecting parts, and first and second pipe members. The base member supports the first and second exhaust treatment devices. The first supporting member supports one side of the base member. The second supporting member supports the other side of the base member. The first connecting part is joined with the first supporting member. The second connecting part is joined with the second supporting member. The first and second pipe members are disposed side by side on a common horizontal plane. An opening section is formed by the edges of the first pipe member, the second pipe member, the first connecting part, and the second connecting part.
