PROBLEM TO BE SOLVED: To simplify the constitution, reduce the failure, and materialize mass flow by arranging a roof-shaped vibration board having the top ridge in parallel to a short side of a rectangle in a discharge port in a hopper of a tank having the rectangular section discharge port. SOLUTION: A vibration hopper 1 is so arranged that a vibration discharge part 20 is arranged under a square tank 10 having a rectangular horizontal cross section. The vibration discharge part 20 is provided with a funnel-shaped vibration body 14 which is vibrated by a vibration source part and suspended from a rectangular cylinder body via a universal connector 19. In the inside of the rectangular cylinder 18, a roof-shaped vibration body 22 supported by a support 21 fixed to the funnel-shaped vibration body 14 is arranged. A square/ round shoot 30 is attached to the bottom of the funnel-shaped vibration body 14 and a screw conveyer 32 is arranged in its lower part via a flexible joint 40. The vibration source part generally performs vertical reciprocating movement, however, those performing lateral reciprocating movement or circular movement are also adoptable.
