<P>PROBLEM TO BE SOLVED: To identify a part in a sealing member arranged on the opening end of a cylindrical body by deformation processing of an opening end part of the cylindrical body. <P>SOLUTION: This part identifying structure in the sealing member S is arranged so as to block up the opening end of the cylindrical body C by the deformation processing to the inside in the opening end part of the cylindrical body C. The structure is formed by applying a mark M identifiable from the external side of the cylindrical body C, to an end surface of the sealing member S, after the deformation processing to the opening end part of the cylindrical body C. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
