PROBLEM TO BE SOLVED: To resolve a former problem that constitution is complicated in a structure detaching a grain tank to a grain raiser in a thresher. SOLUTION: This combine harvester raises grain threshed in a thresher mounted on a chassis by a grain raiser 2 and receives them in a grain tank 3. In the combine harvester, the grain tank 3 is made of a synthetic resin material and provided so as to have a feeding port 16 communicating with a discharging port 14 of the grain raiser 2 at a side in its upper part and to open its bottom face. Then the grain tank 3 is superposed and engaged with a lower part tank having a longitudinal spiral and being fitted to an upper face of the chassis and is pulled to the discharging port 14 part of the grain raiser 2 by a detaching tool 4 and fixed.
