Provided is a shot peening device with which recovered projection material and foreign bodies can be more precisely separated while inhibiting an increase in the size of the device. The shot peening device is provided with: a projector (42) which projects projection material onto a workpiece (W); recovery mechanisms (52, 54) which recover the projection material projected by the projector; and a wind power sorting mechanism (62) in which recovered projection material is allowed to fall freely while an upward air current is applied to the recovered projection material, and foreign bodies included in the recovered projection material are separated from the recovered projection material. |
