PROBLEM TO BE SOLVED: To provide a vibration screen vibrating with lesser action force and accurately separating light specific gravity matter from heavy specific gravity matter. SOLUTION: Multiple pairs of balancing links forming vibration function of a screen body are provided with rigidity; a counter weight balancing to the total weight of the screening body and a treating object is fixedly provided; separation curtains having functions of regulating inlet and outlet amount of air more than required, and of sending the treating object to a charging or discharge port following vibration of the screening body are provided at the charging port supplying the treating object to the filter body, the discharge port for the light specific gravity matter located at a lower side of the tilted filter body, and a discharge port for fine particles passing through a meshed plate toward the lower side, respectively, for enhancing the accuracy of classification; and guide plates are provided at an upper part of the meshed plate from a high part of the filter body to the charge port with a space suited to the property of the treating object, to form a high speed air passage.
