Abstract: A hydraulic excavator includes an engine, a rotating frame, a vehicle body frame, a diesel particulate filtering device, a selective catalytic reduction device and a connecting pipe. The rotating frame supports the engine. The vehicle body frame is provided in a standing manner on the rotating frame, and includes a plurality of column members. The a diesel particulate filtering device and the selective catalytic reduction device process exhaust from the engine, and are supported by the vehicle body frame. The connecting pipe has an extendable bellows part in at least a portion. The connecting pipe connects the engine and the diesel particulate filtering device. The bellows part is located further away from the engine as the bellows part inclines further downward.
