め、筆記具部材の挿着前に軸筒端部のバリの除去作業を
余儀なくされている。However, in general, the barrel of a writing instrument is almost a synthetic resin injection-molded body, and after injection molding, a thin-walled projection, that is, a so-called burr is easily generated at the end of the barrel. In a case where the writing implement member is inserted into the barrel in which the burr has occurred, in the conventional fitting structure, the burr is sandwiched between the end of the opening of the barrel and the flange of the writing implement member, and the flange is opened. The end cannot contact the end, which tends to cause incomplete insertion of the writing instrument member or defective assembly (see FIG. 4). Therefore, it is necessary to remove the burrs from the end of the barrel before inserting the writing implement member.

An object of the present invention is to provide a writing instrument member fitting structure that can be securely inserted.
