Claims

[Scope of Claim for Utility Model Registration] (1) A rotary drive source that is inserted into a hole so as to be freely advanced and retracted by a feeding device, a holder provided on the rotating shaft of the rotary drive source, and one end of which is attached to the holder so as to be able to swing freely. The grindstone includes a connected support arm, and a grindstone provided at the other end of the support arm and pressed against the inner surface of the hole by centrifugal force caused by the rotation of the rotational drive source and polishing the inner surface. A hole surface polishing device featuring: (2) The feed device includes a feed screw shaft that is connected to a rotational drive source and is slidably supported in a direction parallel to the axis, a female threaded pipe that is screwed onto the feed screw shaft, and a female threaded pipe that is connected to the feed screw shaft and is slidably supported in a direction parallel to the axis. The hole internal surface polishing device according to claim 1, further comprising a drive mechanism that rotates and moves the feed screw shaft along the sliding direction.
