A dust-discharging communication portion H communicating with a dust-discharging treatment device 30 disposed on the rear portion side of the threshing chamber 12 is formed behind the threshing chamber 12, and a front side dropping portion 45 having a front dropping member 54, and a rear side dropping portion 46 having a rear side dropping member 58 having a larger mesh scale than the front side dropping portion 45 are disposed in the lower portion of the dust-discharging communication portion H.
