SOLUTION: An image recognizing part 13 detects and judges the presence of a burr 12 on an inserting hole 11 for the sealing rubber 1 in the holding part 2 at the bottom of an image recognizing part 13 and detects and judges which of the two inserting holes 11 has more burrs 12. Then, a turn table 5 is rotted at a prescribed angle, and a new holding part 2 is transferred to the image recognizing part 13 and the holding part 2 which has been at the image recognizing part 13 is transferred to an aligning part. Then, the result signal detected and judged by the image recognizing part 13, namely, the inserting hole 11 without burr or with less burrs is rotated to a position to be detected by a detecting sensor 7. Then the set position of the inserting hole 11 for the sealing rubber 1 is detected by the detecting sensor 7.
