<P>PROBLEM TO BE SOLVED: To provide a locking structure of a barrel to a clip, which can dispose the clip at a predetermined position. <P>SOLUTION: The locking structure of the barrel to the clip includes a plurality of vertical ribs 75 protruding outward from an outer peripheral surface of an inner cylinder 70 along with a longitudinal direction of the inner cylinder 70. The vertical ribs 75 are engaged with recessed channels formed on an inner peripheral surface of a locking part 24 of a clip body 21, and the clip body 21 is thereby locked to the inner cylinder 70 to be impossible to be rotated in a circumferential direction. A male threaded part 77 is provided forward of a front flange 73, and this male threaded part 77 is engaged to be screwed with a female threaded part 13 formed on an inner peripheral surface of the barrel 10. A front end of the vertical rib 75 becomes a contact part 71 brought into contact with a rear end edge 12 of the barrel 10, and this contact part 71 is brought into contact with the rear end edge 12 of the barrel 10, thereby ending screwing of the inner cylinder 70 with the barrel 10. When this screwing is ended, a gap 90 is formed between the locking part 24 of the clip body 21 and the rear end edge 12 of the barrel 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
