A tractor 1 according to the present invention includes: an engine 5 mounted on a traveling machine 2; an aftertreatment device 32 that purifies exhaust gas from the engine 5; and a vertically elongated tail pipe 39 through which the exhaust gas that has passed through the aftertreatment device 32 is discharged outside. The aftertreatment device 32 is vertically disposed in front of a steering part 7 on the traveling machine 2 such that the exhaust gas is directed from bottom to top. An outlet pipe 111 projecting upward is provided on the top-surface side of the aftertreatment device 32. The inside diameter of the tail pipe 39 on the exhaust-gas entrance side is set to be larger than the outside diameter of the outlet pipe 111. The outlet pipe 111 is inserted into the tail pipe 39 from the exhaust-gas entrance side so as to communicate therewith. The outside of the aftertreatment device 32 is covered with an outer cover body 113.
