PROBLEM TO BE SOLVED: To provide a roller burnishing processing device capable of heightening processing efficiency of the outer peripheral surface of a shaft part of a crank shaft by a simple constitution, while avoiding interference of a balance weight.SOLUTION: A roller burnishing processing device 10 includes a pair of burnishing rollers 14, 16 extending along the axial direction of a crank shaft 100, a pressing mechanism 18 and a support part 20. The pressing mechanism 18 has a first backup roller 22, and the burnishing rollers 14, 16 have a contact with a shaft part 102 in the juxtaposed state along the circumferential direction of the shaft part 102 of the crank shaft 100.SELECTED DRAWING: Figure 2 |
