PROBLEM TO BE SOLVED: To provide a simple and efficient vibrating feeder, in which a powdery resin is accurately supplied and sent out at constant amount in order to perform spray coating for a screwed fastener. SOLUTION: The vibrating feeder is comprised of a housing 12 forming a powder reservoir 18, a powder storage hopper 14 having a discharge port 15 provided so as to supply powder to the reservoir 18, a distribution block 16 having one or a plurality of nearly vertical filling tubes 44, a plurality of discharge ports 26 extended from the reservoir 18 to the filling tubes 44 of the distribution block 16 and a vibrating device 49 fitted with the housing 12. Further, the housing 12 supports a regulative barrier 34 performing a role as a dam, in which the flow of a powdery resin into the discharge ports 26 is controlled or quantitative feeding is performed.
