PROBLEM TO BE SOLVED: To solve a problem that, in a conventional hopper with the bridge preventive function, a partition provided in the hopper is not smoothly rocked, and a bridge cannot be broken. SOLUTION: This hopper has a throw-in port on its upper part and a screw conveyor 3 arranged on its lower part, and a partition plate 5 erected in the hopper above the screw conveyor 3 parallel to a rotary shaft 3d of the screw conveyor 3. A part of the partition plate is pivotably locked to a horizontal shaft 6 orthogonal to the rotary shaft 3d of the screw conveyor 3, and the partition plate 5 is rocked around the horizontal shaft 6 by the rotation of the screw conveyor 3.
