ップ本体に頭冠を取り付けてなる。In order to achieve the above object, according to the present invention, there is provided a writing instrument cap having a cap attached to a tip of a cap body, wherein the cap has a projection having an insertion hole. The projection is inserted into the opening at the tip of the cap so that the projection provided on the outer periphery of the projection fits over the projection of the opening and fits over the projection of the opening. The fitting piece having the first engaging portion,
The cap is attached to the cap main body by dropping and press-fitting while pushing over the second engaging portion provided on the inner peripheral surface of the insertion hole of the projection.

て本発明の筆記具のキャップを得る。BEST MODE FOR CARRYING OUT THE INVENTION A projection having an insertion hole is provided on a crown, and the projection is formed on an opening provided at the tip of a cap, a projection formed on an inner peripheral surface of the opening, and an outer periphery of the projection. According to the present invention, the cap is attached to the cap main body by inserting and inserting the fitting pieces so that the provided projections are fitted over the caps, and dropping the fitting pieces into the insertion holes of the projections from the inner hole side of the cap and press-fitting. Obtain a writing instrument cap.

とである。The fitting piece according to the present invention is a member which is inserted into the insertion hole of the crown from the inner hole side of the cap and press-fitted, and is a member other than the cap body such as a core. Further, the drop-in press-fitting means that one member is inserted into the other insertion hole, and an engaging portion provided on one outer peripheral surface is fitted over the engaging member provided on the inner peripheral surface of the other inserting hole while press-fitting. It is a fitting method that fits.

頭冠を抜け落ちしにくくすることができる。According to the present invention, not only is the projection of the opening and the projection provided on the outer periphery of the projection fitted over each other to prevent the cap from falling off, but also to prevent the cap from dropping from the inner hole side of the cap. By dropping the fitting piece into the insertion hole of the protrusion formed in the part and press-fitting it, the insertion hole is pushed and expanded,
Since the fitting force between the crown and the cap body is increased, and the fitting piece is provided in the insertion hole, it is also possible to prevent the diameter of the protrusion from shrinking due to a dimensional change over time.
It is possible to make it difficult for the cap to fall off.
【００１３】また、頭冠が円周方向への回転してしまう

嵌合力を低下させてしまう。そこで、キャップ先端部に
形成した開口部および頭冠部の突起部に回転防止のため
の平地部を形成することにより円周方向への回転を防止
することができるので好ましい。When the crown is rotated in the circumferential direction, the fitting portion between the crown and the cap body is worn, and as a result,
The fitting force is reduced. Therefore, it is preferable to form a flat portion for preventing rotation at the opening formed at the tip of the cap and at the projection of the crown, since rotation in the circumferential direction can be prevented.

で、特に有効である。Further, in the case of a writing instrument cap in which a clip is formed or attached integrally with a crown, or a writing instrument cap in which a clip is clamped between a crown and a cap body, when the clip is sandwiched between clothes or the like, For example, lifting the clip in the direction of arrow F in FIG. 1 is particularly effective because force frequently acts in the direction in which the crown of the head falls off.
