<P>PROBLEM TO BE SOLVED: To provide a clip fitting structure for a writing utensil with such advantages the assembly of the clip is feasible under simple construction, a comparatively thicker object to be inserted can be inserted, and the clip is free from an operating failure of the clip due to the wear of each member for fitting the clip, even in case the operation to insert the object into the clip is repeated for a long time. <P>SOLUTION: First, a partition part 5, formed integrally with a barrel 2, for defining the interior of the barrel 2 as the front part and the rear part, and a first guide groove 18 are arranged inside the barrel 2. Next, the clip 1 is composed of a clip body 6 and a leg part 7, then an extension part 8 is arranged at the bottom 7a of the leg part 7, and a first fitting protrusion 9 is arranged at the apex of the extension part 8 and an arcuate second fitting protrusion 11 is arranged on the rear wall surface 10 of the leg part 7. Further, the clip 1 is inserted into a clip fitting hole 3 by arranging a coil spring 15 at the extension part 8, and the first fitting protrusion 9 is fitted to the first guide groove 18. Behind the clip 1, a plug member 21 with an arc-shaped second guide groove 24 is interlocked to the forward wall surface 22 and the second fitting protrusion 11 is fitted into the second guide groove 24. <P>COPYRIGHT: (C)2009,JPO&INPIT |
