PROBLEM TO BE SOLVED: To provide an apparatus for discharging grain lighting a discharging auger, reducing vibration, load and burden on a fixing part and a supporting part, improving durability and transportation suppressing clogging, smoothening extension and contraction a cost reducing, suppressing husking of grain during transportation and improving abrasion resistance. SOLUTION: This apparatus for discharging grain has a laterally discharging auger 6 dividedly formed into a stationary auger 7 connected to a vertically grain lift 5 for discharging grain in a grain tank 4 and a moving auger 8 strechably fitted to the stationary auger 7. A stationary auger screw 10 whose length is not changed regardless of extension and contraction of the moving auger 8 and a stretchable screw 20 whose length is changed according to the extension and contraction of the moving auger 8 are installed in the laterally discharging auger 6 and the stretchable screw 20 is made of a synthetic resin.
