【考案の詳細な説明】
（産業上の利用分野）
本考案は、筆記具のキヤツプ内面に取り付けら
れ、軸筒へのキヤツプ嵌合時、軸筒への位置を安
定させるために軸筒と当接する内方への膨出部を
有する筆記具のキヤツプにおけるバネに関する。[Detailed description of the invention] (Field of industrial application) This invention is attached to the inner surface of the cap of a writing instrument, and when the cap is fitted to the barrel, it comes into contact with the barrel in order to stabilize its position on the barrel. The present invention relates to a spring in a writing instrument cap having an inward bulge.

ネと軸筒表面との摩擦により、軸筒表面に傷が生
じるという問題がある。(Conventional technology and its problems) Conventionally, in writing instruments, the barrel is fixed to the cap so that it does not shake, and when the cap and barrel are fitted, the inward expansion is done to create a damp feeling. Although a spring having a projecting portion is fixed to the inner surface of the cap, there is a problem in that as the number of times the cap is opened and closed increases, the friction between the spring and the surface of the barrel causes scratches on the surface of the barrel.

も限りがあり、問題の多いものである。 Solutions to this problem include surface treatments such as anodizing and chrome plating to harden the surface of the barrel, improving wear resistance and durability and preventing scratches due to friction, and providing the contact point between the barrel and the spring at the tip of a cartridge so that it can be replaced if scratched. However, the method of hardening the surface of the barrel by surface treatment does not allow the use of other surface treatments such as gold plating or painting, and is unable to meet the growing demand for diversifying exterior designs through surface treatments in recent years. Cartridges that allow replacement if scratched are disposable and are therefore cost-constrained, making it difficult to achieve exterior designs that meet the above demands, and the exterior designs that can be achieved are limited, resulting in many problems.
