Is provided.

  In the decorative body 20 having the above-described configuration, the back surface 20a of the mounting portion 22 is substantially flush with the back surface of the sandwiching piece portion 13 so that the ball portion 14 hardly interferes with the object to be sandwiched and has good design properties ( (See FIG. 5).

Next, the manufacturing method of the clip 1 for writing instruments of the said structure is demonstrated.
First, as shown in FIG. 1, the decorative body 20 is moved backward so as to cover the sandwiching piece 13 of the clip body 10 from the front side. Then, the front end of the sandwiching piece 13 is pressed against the opening 22a (see FIG. 3) at the rear end of the decorative body 20, so that the space between the locking projections 22b1 and 22b1 of the decorative body 20 (see FIG. 4) is elastic. To spread.
If the rearward movement is further continued, the locking projections 22b1 and 22b1 of the decorative body 20 fit into the locking recesses 13a and 13a, respectively, and the contact portion 22b2 (see FIG. 3) in the decorative body 20 is sandwiched. While approaching or abutting the front end portion of the piece 13, the engaging portion 22 b 21 of the corresponding contact portion 22 b 2 is locked so as to cover the locked portion 13 b (see FIG. 1) of the front end of the sandwiching piece 13.

In this mounted state, the abutting portion 22b2 (see FIG. 3) of the decorative body 20 approaches or abuts the front end portion of the sandwiching piece portion 13, and the front end portions of the locking projections 22b1 and 22b1 of the decorative body 20 are both coupled. The decorative body 20 does not move in the front-rear direction with respect to the clip body 10 because it approaches or abuts against the inclined front end face 13a1 (see FIG. 1) in the retaining recesses 13a, 13a.
In addition, the locking portion 22b21 (see FIG. 3) of the decorative body 20 is locked on the front side of the ball portion 14 so as to cover the locked portion 13b (see FIG. 1) at the front end of the sandwiching piece portion 13, Moreover, since both the locking projections 22b1 and 22b1 of the decorative body 20 are fitted to the both locking recesses 13a and 13a on the rear side of the ball portion 14, the decorative body 20 is pulled outward in the axial tube radial direction. However, the decorative body 20 does not easily come off.
Moreover, since the ball | bowl part 14 protrudes to the axial cylinder outer peripheral surface side rather than the back surface 20a of the decoration body 20, a to-be-clamped object (for example, paper, cloth, etc.) is pinched | interposed between the ball | bowl part 14 and the axial cylinder a of a writing instrument. When the object to be clamped is pulled out, the object to be clamped is rubbed or caught on the decorative body 20, and the decorative body 20 is displaced or dropped, or the feeling of use is impaired. There is nothing.

When the decorative body 20 is removed or replaced with a different design, the locking protrusions 22b1 and 22b1 of the decorative body 20 may be elastically deformed by the reverse operation.
More specifically, when the attached decorative body 20 is pulled slightly forward with respect to the clip body 10, the locking protrusion 22b1 of the decorative body 20 is elastically deformed so as to ride on the inclined front end face 13a1. Since it disengages from the locking recess 13a, the decorative body 20 can be easily removed.

  In addition, according to the said Example, although the ball | bowl part 14 did not interfere with a to-be-clamped object, and the design property was favorable, the back surface 20a of the decorative body 20 was substantially flush with the back surface of the clamping piece part 13 ( As another example, as another example, the back surface 20a of the decorative body 20 can be made deeper than the back surface of the holding piece 13 to make it less likely to interfere with the object to be held.

  Further, as another example, on the rear side of the ball part 14, the back surface 20 a of the decorative body 20 is placed closer to the outer peripheral surface side of the shaft cylinder than the back surface of the holding piece part 13, as in the writing instrument clip 2 shown in FIG. It is possible to make it protrude and to partially cover the back surface of the sandwiching piece 13. According to this aspect, it is more effectively prevented that a portion of the decorative body 20 on the rear side of the ball portion 14 is pulled outward in the axial tube radial direction and the decorative body 20 is detached. be able to. The cross-sectional position in the axial direction in FIG. 6 is the same as that in FIG.
