SOLUTION: The roller burnishing tool comprises a roller 5, a shank 3, a retainer 6 for retaining the roller so as to rotate and move to the preset tilting direction, mandrels 12, 14 which hold the retainer 6 so as to rotate and axially slide and are provided with an approximately chevron shape recessed portion 12a formed to retain the roller 5, and a first energizing means 10 for energizing the retainer 6 in the forward direction of the tool. The roller burnishing tool further comprises a mechanism for adjusting the machining diameter of the tool by moving the roller 5 along the recessed portion 12a formed on the mandrel 12 by receding the retainer by pushing the roller 5 against the portion to be rounded.
