PROBLEM TO BE SOLVED: To provide a wind resistant damping device for a bridge capable of efficiently damping the bridge and being reduced in size. SOLUTION: A plurality of windmills 7 are installed on a bridge at specified intervals in axial direction. Also, the windmills 7 are installed near the end part of the bridge in lateral direction, particularly, near a portion A where the shape of the bridge deforms in a direction for producing the peeling of flow. In addition, the device comprises generators 9 using the windmills 7 as drive sources and a storage device 11 for storing electricity generated by the generator 9. The device also comprises a flat blade extending in the axial direction of the bridge, a drive device for rotating or stopping the flat plate blade, and a control device for controlling the drive device based on input signals from an anemometer installed on the bridge.
