Abstract

This vehicle frame includes a plurality of pillar members positioned on a revolving frame so as to be upright. A first exhaust treatment device is supported by the vehicle frame. The first exhaust treatment device treats exhaust from an engine. A connecting tube has an expandable bellows part in at least one section thereof. The connecting tube connects the engine and the first exhaust treatment device. The connecting tube includes a fixed part fixed to the vehicle frame. The fixed part is positioned on the connecting tube between the bellows part and the first exhaust treatment device.
