<P>PROBLEM TO BE SOLVED: To overcome the problem such that the appearance and value of a product are decreased because a mounting seat for a clip is subtly moved and displaced, in a process for screwing a top crown into a barrel. <P>SOLUTION: In a structure for mounting the clip on the barrel, a diameter- reduced part is formed on the upper part of the barrel; a protrusion is formed on the upper part of the diameter-reduced part; not only a large-diameter part, into which the diameter-reduced part of the barrel is to be fitted, but also a recess, with which the protrusion is to be engaged, are formed in the inner surface of the mounting part of the clip; and the mounting part of the clip is held in a sandwiched manner and fixed by means of the barrel and the top crown. <P>COPYRIGHT: (C)2004,JPO |
