するようにした構造において、尾栓を弾力性材質
よりなるものとし、また、尾栓の前記内孔に対す
る嵌合部には、幅広環状部と幅狭環状部とを、幅
広環状部が幅狭環状部よりも内孔の開口端側に位
置するよう、また、幅広環状部における径が幅狭
環状部における径よりも大きくなるように設け、
これら幅広環状部と幅狭環状部とが軸の内孔から
受ける縮径変形による嵌合力を、幅狭環状部にお
けるよりも幅広環状部において強くなしてなる筆
記具などの尾栓嵌合構造。 In the structure in which the tail plug is fitted into the rear end opening of the inner hole of the shaft to form a liquid seal, the tail plug is made of an elastic material, and the fitting part of the tail plug with respect to the inner hole is made of a resilient material. The wide annular part and the narrow annular part are arranged so that the wide annular part is located closer to the open end of the inner hole than the narrow annular part, and the diameter of the wide annular part is smaller than the diameter of the narrow annular part. Set it so that it becomes larger,
A tail plug fitting structure for a writing instrument, etc., in which the fitting force due to the diameter reduction deformation that the wide annular part and the narrow annular part receive from the inner hole of the shaft is stronger in the wide annular part than in the narrow annular part.
