PURPOSE: To provide an inner diameter polishing device which can go on with the feed travel motion of a film abrasive material at a stable feeding speed for a polishing area while being free of rocking vibration in the inner diameter polishing device using the film abrasive material.
CONSTITUTION: In the inner diameter polishing device including a film abrasive material feed mechanism and a vibration section 7 for super polishing, the film abrasive material feed mechanism is divided into a film vibration section and a non-oscillatory section, paired film guide rolls 11 and 12, 14 and 15, each pair of which are faced to each other, are attached to the aforesaid sections respectively, and the inner diameter polishing device is so constituted as to be characterized in letting the film abrasive material 10 running between the respective guide rolls be in approximate circular arc motion between the guide rolls 11 and 12, and also between the guide rolls 14 and 15 of the vibration section and the non-oscillatory section.
