PROBLEM TO BE SOLVED: To provide a roller burnishing tool in which the parallel degree of a tool roller is guaranteed even though the installing error of the tool roller to a holder main body exists, the structure is simple, the cost is low, and a tool roller with a thin diameter can be used, and the processing liquid can be fed easily, in a roller burnishing tool to finish the shoulder surface of the outer diameter groove of a crackshaft. SOLUTION: A cylindrical tool roller 1 is set by contacting to both surfaces of a rotary blade 2, the rotary blade 2 is installed rotatable to a holder main body 3, and the tool roller 1 is locked rotatable to a roller groove 3c formed to the holder main body 3. The rotary shat of the tool roller 1, and the tangent of the tool roller 1 and the rotary blade 2, are set on the same plane, and the rotary shaft of the tool roller 1 is arranged to cross at the right angle with the rotary shaft of the rotary blade 2. |
