PURPOSE:To make it possible to obtain a vibrating type granular material supply device which may precisely weigh a granular material with the use of a weighing hopper, by providing a flow limiting damper for limiting the discharge volume of the granular material. CONSTITUTION:when the weight of a granular material received in a Weighing hopper 8 becomes a predetermined value, a control means 84 deenergizes a vibration generator 6 and a valve means but energizes an actuator 78. After the deengergization of the vibration generator 6, the vibration of a trough 4 is ceased, and therefore, the transfer of a granular material from a stationary hopper 2 is stopped. Further, a flow limiting member 40 is turned by means of an arm member 58 in the direction opposite to the direction of the arrow 68, and is therefore located at its rest position. Further, when the actuator 78 is energized, a cut member 76 is located at its closed position at which it inhibits the supply of the granular material, thereby it is possible to ensure the inhibition of the supply of the granular material into the weighing hopper 8.
