The purpose of the invention is to obtain a shot peening device that is designed to be smaller while being capable of adjusting the particle size of the shot medium. A pressurizing tank (42) is disposed below the peening position (24X) at which the workpiece (12) is peened and shot medium that has been shot is received into the pressurizing tank (42). The outlet side of the pressurizing tank (42) is capable of communicating with the peening machine. One end of a discharge-side pneumatic conveying pipe (54) provided with a suction function is connected between the peening position (24X) and the pressurizing tank (42), and the other end of the discharge-side pneumatic conveying pipe (54) is connected to a separator (68). The separator (68) is also connected to one end of a supply-side pneumatic conveying pipe (76) provided with a suction function. The other end of the supply-side pneumatic conveying pipe (76) communicates with the peening chamber (16). |
