PROBLEM TO BE SOLVED: To make usable a plate spring of a thin thickness by preventing vibration of the plate spring after grain-removing motion by providing a grain remover with a damping member for inhibiting vibration to be generated after elastic change of a removing plate. SOLUTION: When a solenoid 24 is functioned, a shaft 23 is functioned from a stationary state to a drop orbit of grains, and the removing plate 25 is pushed. Then, the removing plate 28 enters the drop orbit of the grain, and the grain is driven out. Though the removing plate 25 is returned to a stationary position after driving out the grain, since the removing plate 25 is formed of a thin plate in this case, though vibration is generated when returned to the stationary state, the vibration generated in grain-removing function is absorbed, and the removing plate 26 becomes in a stationary state. Thereby, the removing plate 25 having a more thinner thickness can be used, and a speed of the grain removing operation and its precision can be improved. Further, the necessity for installing the damping member at another place is eliminated.
