PROBLEM TO BE SOLVED: To achieve the smooth movement and the prevention of the leakage of shots. SOLUTION: In a device for performing ultrasonic shot peening, air from an air feeding pipe 26 is discharged into a shot holder 17, a number of shots 22 are shot up and repeatedly collide with one another between a vibration unit 20 and a surface of a plate member 7, and shot peening treatment to the surface of the plate member 7 starts. An operation head pressing device 12 together with an operation head 10 moves along a welding part of the surface of the plate member 7. In the motion, only a brush member 23 extended downward longer than a chamber member 21 and a lower end of a rubber cover member 24 come into contact with the surface of the plate member 7, thereby reducing friction and achieving the smooth movement.
