姿勢切換機構を設けてある点にある。According to a first aspect of the invention, a polishing member is provided on a cantilevered rotary shaft member, and the polishing member is rotated while being pressed against a surface to be polished. In the polishing tool, a plurality of rod-shaped polishing members are arranged radially around the rotation axis of the rotary shaft member, and one end side of each of the polishing members is arranged along the rotation axis direction. Swingably supported on the rotary shaft member,
With respect to the posture of the polishing member, a first posture in which the free end side is close to the rotary shaft core side and a state in which the free end side is directed to the rotary shaft member base side are the first posture. The point is that a posture switching mechanism that can switch to a second posture that is separated from the rotation axis side is provided.
