Therefore, the moving direction of the processing tool 13 with respect to the frame body 21 can be set to the direction perpendicular to the braking surface 2c. This makes it possible to stabilize the force with which the processing tool 13 is pressed against the braking surface 2c. Further, it is possible to perform stable processing without causing unevenness in processing, that is, non-uniformity in the amount of scraping.
  • the frame 11 is divided into a frame body 21 and a frame division body 22. Then, the frame spring 28 generates a force for moving the frame divided body 22 to the sandwiching position side.
