いる。 The main body of such refills for writing instruments is usually made of metal, but due to the reduction in cost in recent years, many of them are made of resin.
On the other hand, the holder having the writing part connected to the tip of the refill main body is exposed even when the refill main body is housed in the outer shaft main body. In particular, as seen in water-based ballpoint pens, metal holders are often used in order to provide durability to the holder itself.

一面を有していた。 However, the biggest problem is that the resin refill body and the metal holder do not connect well due to differences in physical properties such as coefficient of thermal expansion, making it easy for them to be pulled out from each other. It has become,
At present, the small diameter portion of the refill main body to which the holder is connected is made thick, and the two are coupled by forcefully press-fitting the two. However, in this case, the small diameter part of the refill main body, which is the connecting part between the two, causes deformation in appearance such as a raised part, and when the refill main body is later stored in the outer shaft main body, the small diameter part of the refill main body Due to the change in dimensions, the storage operation cannot be carried out smoothly, or the writing part cannot be moved in and out, and other new problems have arisen, which is an undesirable aspect.
（問題点を解決するための手段）
本考案は以上の知見に基づきなされたもので、
大径部及び小径部を有する樹脂製のリフイル本体

諸問題を一掃した極めて優れた筆記具用リフイル
を提供することを目的とするものである。(Means for solving the problem) This invention was made based on the above knowledge,
The object of the present invention is to provide an extremely excellent refill for a writing instrument that eliminates all the conventional problems by making simple improvements to the small diameter part of a resin refill body having a large diameter part and a small diameter part.
（実施例）
以下、本考案の筆記具用リフイルを添付図面に
基づき詳細に説明する。(Example) Hereinafter, the writing instrument refill of the present invention will be described in detail based on the accompanying drawings.

目的が十分に達成できるものである。 1 to 3 show an embodiment of the present invention, in which a refill main body 11 made of a resin such as polypropylene or polyethylene has a large diameter portion 11a that accommodates an ink absorber (not shown) such as batting. and a small diameter part 11b continuous to the large diameter part 11a, and the inner wall of the small diameter part 11b is made of stainless steel,
A metal pipe 12 made of nickel silver, brass, or the like is buried by a well-known insert molding method or the like so that its inner surface and the inner wall of the small diameter portion are substantially flush with each other. Reference numeral 13 is
A holder made of metal such as stainless steel, nickel silver, or brass, having a writing part 13a (shown with a ballpoint pen in the figure) connected to the opening of the small diameter part 11b of the refill main body 11; The rear connecting portion 13b of the refill body 13 is press-fitted into the small diameter portion 11b of the refill main body 11.
As a result, the holder 13 and the refill main body 11 are bonded metal to metal, which improves the bonding strength between the two and maintains the original dimensions without causing any bumps in the small diameter portion 11b. The intended purpose can be fully achieved.
