PROBLEM TO BE SOLVED: To provide a thresher which can prevent loss from the dust outlet and can efficiently recover grains by the simple improvement of a straw rack, at a low cost. SOLUTION: This thresher for separating treated materials by the shaking of a shaking separator B equipped with the straw rack 8 below a threshing chamber A, separating the treated materials delivered to the straw rack 8 with separation winds from a winnower 10, and conveying the treated materials to a dust-discharging port 23 on the downstream side of the conveying direction is characterized in that the straw rack 8 comprises the first straw rack 8A disposed in an upward inclined direction that the downstream side of the treated material-conveying direction is higher, and the second straw rack 8B whose starting end portion is placed below the downstream side portion of the first straw rack 8A and is arranged in an upward inclined direction that the downstream side of the treated material-conveying direction is higher.
