PROBLEM TO BE SOLVED: To provide a grain stirring device capable of extending an interval for maintenance. SOLUTION: In a stirrer 56, a guide rail 160 permits rotation of a guide shaft 64 by making a rotation roll 138 of the guide rail 160 rotate about, as a center axis 142, a direction parallel with the axial direction of the guide shaft 64. A driven support frame 80 is permitted to move in the axial direction of the guide shaft 64, by making a rotation roll 138 of the driven support frame 80 to rotate about, as the center axis 142, a direction vertical to the axial direction of the guide shaft 64. The rotation rolls 138 of the guide rail 160 and the driven support frame 80 are set rotatable about the certain center axis 142. Therefore, the rotation rolls 138 can be formed in a closed dust-proof structure for preventing degradation of the rotation performance by dust or the like, and the period required for maintenance of the stirrer 56 can be extended by extending service life of the rotation rolls 138.
