PROBLEM TO BE SOLVED: To improve grain-discharging efficiency by forming the horizontal auger of the grain-discharging device from a fixed cylinder and the movable cylinder and by providing a grain-discharging device of a work vehicle, capable of moving a grain-discharging port between the downstream side and the upstream side of a horizontal auger in the grain-carrying direction, and to reduce weight and cost by preventing a large moment from acting on the base portion of the horizontal auger, when a movable cylinder is extended. SOLUTION: In the grain-discharging device of a work vehicle, the horizontal auger 5 comprises a fixed cylinder 5a and a movable cylinder 5b capable of being fit onto the fixed cylinder 5a and extended or contracted in the longitudinal direction, and a screw 5c is disposed in a position portion approximately above a grain-discharging port 6 in the movable cylinder 5b. The work vehicle is manufactured by disposing a grain tank 3 for temporarily storing grains and a vertical auger 4 and a horizontal auger 5 for discharging the grains temporarily stored in the grain tank 3 on a frame 2 having a travel device 1.
