PROBLEM TO BE SOLVED: To provide a peening processing device, usable in a wide range portion such as a narrow part, without reducing processing efficiency even if an inclination angle of an impact pin is enlarged, by easily achieving a vibration direction conversion of a larger angle than before.SOLUTION: A peening processing device comprises: a waveguide for forwardly guiding mechanical vibration generated by a mechanical vibration generator; a pin group excited by the mechanical vibration, consisting of a plurality of impulsively vibrating pins connected in series and transmitting impulsive vibration to a processed; and a pin holder having a guide hole for vibratably holding the pin group in the pin axis direction. In the peening processing device, the plurality of pins are mutually connected by point contact at end parts, and the mutual vibration directions are inclined at the connection part. |
