PROBLEM TO BE SOLVED: To facilitate the maintenance of the thresher adjacent to a grain tank from the tank side and the maintenance of a grain-discharging screw. SOLUTION: The grain tank is constituted with an upper tank 12 having the charge opening 11 and a lower tank 13 equipped with the grain-discharging screw 14. A link 18 is set to the support 17 that stands upright on the travelling machine body 2 so that the link 18 is swingably displaceable between the working position where the lowermost opening 22 of the upper tank 12 is connected to the opening 23 of the lower tank 13 and the charging inlet 11 is connected to the outlet 10 of a reversibly lifting conveyer 5 and the not-working position that is set on the reversely lifting conveyer 5 side and is made apart from the opening 23 of the lower tank 13 and the charging inlet 11 apart from the outlet 10. Further, a spindle 19 is vertically arranged on the free edge of the link 18 so that the upper tank 12 is swingably supported between the not- working position and the maintenance position that opens the upper part of the lower tank 13.
