Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gravel removing machine of a low cost, which increases a treatment efficiency by enlarging an area of a sorting board of the gravel removing machine, and further, suppresses an increase of the burden due to a load increase accompanying it. SOLUTION: A fixing pin or hole is provided inside a machine casing 1 and on a side surface of an air channel 7, and a suspended spring 25 is stretched between the machine casing 1 and the air channel 7 with a hook or the like of the suspended spring 25. When the air channel 7 and the sorting board 6 swing by the rotation of a motor 16, the suspended spring 25 supports the load of the air channel 7 and the sorting board 6 together with front and rear rods 9, 10 to enable a decrease of the load affecting a rotating portion. Further, even if the sorting board 6 has a larger area than that of the conventional one, it is possible to minimize a reinforcement carried out to the rotating portion and suppress the cost.
