<p>The present invention addresses the problem of providing an exhaust treatment unit capable of connecting a diesel particulate filter device and a selective reduction catalyst device via a connecting tube, even if a shift occurs in the relative positions and/or relative orientations of the diesel particulate filter device and the selective reduction catalyst device. This exhaust treatment unit for treating the exhaust from the engine of a work vehicle is equipped with a diesel particulate filter device, a selective reduction catalyst device, and a connecting tube. The diesel particulate filter device and the selective reduction catalyst device treat the exhaust. The connecting tube connects the diesel particulate filter device and the selective reduction catalyst device. The connecting tube includes a plurality of spherical joints. The connecting tube has a first tube section on one end thereof, and a second tube section on the other end thereof. The plurality of spherical joints include a first spherical joint, a second spherical joint, and a third spherical joint.</p> |
