When the dent removing gear is tilted and meshed with the work gear in the tooth thickness direction, the dent removing gear is engaged with the work gear at one diagonal corner of the four corners of the teeth of the work gear. The dents in this area are removed by pressure contact from the area near the pitch circle at the corner of the work piece to the tooth tip side, and when the dent removing gear meshes with the work gear at an angle to the other side in the tooth thickness direction, the dents are removed. The gear is pressed against the other diagonal corner of the four corners of the work gear from the vicinity of the pitch circle to the tooth tip side, and the dents in this area are removed, and the dent removing gear is removed from the work gear. On the other hand, when the teeth are tilted to one side in the tooth height direction and engaged, the dent removing gear is pressed against the bottom side of one corner in the tooth width direction of the teeth of the work gear, and the dents in this area are removed. When the dent removing gear meshes with the work gear at an angle to the other side in the tooth width direction, the dent removing gear is pressed against the bottom side of the other corner in the tooth width direction of the teeth of the work gear. Partial dents are removed.
