PROBLEM TO BE SOLVED: To provide a spreading device for suitably preventing bridging phenomenon of a spreading material. SOLUTION: The spreading device 11 has a holder 31 to hold the spreading material. A plurality of stirring members 41 are placed in a lower part of the holder 31 and the spreading material is stirred by reciprocally turning the stirring members around a vertical rotational center axis X. The spreading device 11 is provided with a plurality of bridge-prevention members 45 to prevent occurrence of the bridging phenomenon of the spreading material in the holder 31. An upper end of the bridge-prevention member 45 is attached to an upper end of the holder 31, and a lower end of the bridge-prevention member 45 is attached to a tip end of the stirring member 41.
