PROBLEM TO BE SOLVED: To solve the problem that the efficiency for transferring grains is reduced because the bending shape can not be formed so as to have a large radius (R) by the contact of a lower connecting and transferring cylinder with a lower supporting device because the lower connecting and transferring cylinder for connecting a lower horizontal transferring cylinder and a vertical transferring cylinder which form a grain-discharging and transferring device, is arranged in a box-shaped lower supporting device for supporting the vertically transferring cylinder so as to be freely turnable, and connects them, in a combine harvester in which grains are sent out from a grain-storing tank by a grain-sending out device, delivered to a grain-discharging and transferring device, and discharged to the exterior of the machine by the air from a blower. SOLUTION: The grains are sent out from the grain-storing tank 4 by the grain-sending out device 7, delivered to the grain-discharging and transferring device 46, and discharged to the exterior of the machine by the air from the blower 44. The lower connecting and transferring cylinder 49b for connecting the lower horizontal transferring cylinder 46b and the vertical transferring cylinder 47 which form the grain-discharging and transferring device 46 is prevented from contacting with the lower supporting device 50b formed into a box-shaped frame body 50c for freely rotatably supporting the vertical transferring cylinder 47, is formed into the bended shape having the large R, and connects the cylinders 46b and 47 so as to be installed in the interior. The lower supporting device 50b is installed in the rear end part of a box-shaped lower supporting frame stand 40, and the rotation fulcrum (a) of the grain-storing tank 4 is installed in the front end part.
