「実施例」
以下、図面に基づき本考案の各種実施例を説明
する。なお、各実施例につき同様の部位には同一
符号を付し重複した説明を省略する。"Embodiments" Hereinafter, various embodiments of the present invention will be described based on the drawings. Note that similar parts in each embodiment are designated by the same reference numerals, and redundant explanation will be omitted.
第１図〜第３図は本考案の第１実施例を示して
いる。本実施例では端部部材は尾栓である。 1 to 3 show a first embodiment of the present invention. In this embodiment, the end member is a tail plug.
筆記具の軸筒１０の後端部に一般外周１１より
少し細径のねじ筒１２が形成され、このねじ筒１
２に尾栓２０が螺合されている。 A threaded barrel 12 having a slightly smaller diameter than the general outer circumference 11 is formed at the rear end of the barrel 10 of the writing instrument.
A tail plug 20 is screwed onto 2.
ねじ筒１２には螺条１３が刻設されており、螺
条１３の大部分は通常ねじ部１４であるが、先端
部には山の高さが低い不完全ねじ部１５が形成さ
れている。ねじ筒１２の先端は螺条１３が途切れ
て案内筒１６をなしている。 A thread 13 is carved into the threaded cylinder 12, and most of the thread 13 is a normal thread 14, but an incomplete thread 15 with a low thread height is formed at the tip. . The thread 13 is interrupted at the tip of the threaded cylinder 12 to form a guide cylinder 16.
尾栓２０は深いハツト形状で、内孔２１に螺条
２２が刻設されている。この螺条は全部通常ねじ
である。尾栓２０の先端２３の外径は軸筒１０の
一般外周１１と同径に設定されている。 The tail plug 20 has a deep hat shape and has a thread 22 carved in an inner hole 21. All of these threads are normal threads. The outer diameter of the tip 23 of the tail plug 20 is set to be the same diameter as the general outer circumference 11 of the shaft cylinder 10.
上記構成において尾栓２０を軸筒１０に取り付
けるには、尾栓２０の内孔２１内に軸筒１０の案
内筒１６を挿通し、そのまま軸筒１０と尾栓２０
とを相互に回転することなく押し込む。すると尾
栓２０の螺条２２の先端と軸筒１０の螺条１３の
不完全ねじ部１５とが当接するようになり、少し
抵抗が生じる。 In order to attach the tail plug 20 to the shaft tube 10 in the above configuration, the guide tube 16 of the shaft tube 10 is inserted into the inner hole 21 of the tail plug 20, and the shaft tube 10 and the tail plug 20 are directly connected to each other.
and into each other without rotating. Then, the tip of the thread 22 of the tail plug 20 comes into contact with the incompletely threaded portion 15 of the thread 13 of the barrel 10, causing a slight resistance.
そこで、その抵抗に抗して強めに尾栓２０を相
対的に押し進めると、軸筒１０の不完全ねじ部１
５は山が低いので、尾栓２０の螺条２２の先端の
山が不完全ねじ部１５の山を乗り越えて進むこと
ができ、第１図に示すように尾栓２０の螺条２２
の先端が軸筒１０の螺条１３の通常ねじ部１４に
当接する。この抵抗は相当に強いので押し進める
ことはできず、そこで尾栓２０は停止する。 Therefore, if the tail plug 20 is relatively pushed forward against the resistance, the incompletely threaded portion 1 of the shaft tube 10
5 has a low crest, so that the crest at the tip of the thread 22 of the tail plug 20 can pass over the ridge of the incompletely threaded portion 15, and as shown in FIG.
The tip of the shaft abuts against the normal threaded portion 14 of the thread 13 of the shaft cylinder 10. This resistance is so strong that it cannot be pushed forward, and the tail plug 20 stops there.
尾栓２０が停止した位置は結果的に螺条２２が
軸筒１０の螺条１３に初期噛み合いした状態であ
り、尾栓２０は軸筒１０に仮装着され、螺条２２
と螺条１３の不完全ねじ部１５とが螺合している
ので、尾栓２０が不用意に脱落することがない。 The position where the tail plug 20 stops is a state where the thread 22 is initially engaged with the thread 13 of the shaft cylinder 10, and the tail plug 20 is temporarily attached to the shaft cylinder 10, and the thread 22 is initially engaged with the thread 13 of the shaft cylinder 10.
Since the threaded portion 15 of the thread 13 is screwed together, the tail plug 20 will not fall off inadvertently.
前記仮装着工程は人手あるいは自動機によりな
される。 The temporary mounting step is performed manually or by an automatic machine.
尾栓２０が仮装着された軸筒１０は自動ねじ込

が本噛み合いして尾栓２０が進み、第３図に示す
ように尾栓２０が軸筒１０に完全に装着され、尾
栓２０の先端２３と軸筒１０の一般外周１１とが
連続した自然な状態になる。 The shaft cylinder 10 to which the tail plug 20 is temporarily attached is sent to an automatic screwing device, and the chuck of the device is inserted into the tail plug 20.
The thread 22 of the tail plug 20 and the normal threaded portion 14 of the thread 13 are fully engaged and the tail plug 20 advances as shown in FIG. The tail plug 20 is completely attached to the barrel 10, and the tip 23 of the tail plug 20 and the general outer periphery 11 of the barrel 10 are in a continuous natural state.
第４図および第５図は第２実施例を示してお
り、尾栓２０の螺条２２の先端部に山の低い不完
全ねじ部２４が形成され、軸筒１０の螺条１３は
全部通常ねじ部１４になる。 FIG. 4 and FIG. 5 show a second embodiment, in which an incomplete threaded portion 24 with a low thread is formed at the tip of the thread 22 of the tail plug 20, and the thread 13 of the barrel 10 is entirely normal. This becomes the threaded part 14.
本実施例でも、尾栓２０を一般外周１１に対し
て少し強めに押し進めると、軸筒１０の螺条１３
の先端部が尾栓２０の螺条２２の不完全ねじ部２
４の山を乗り越え、第４図に示すような初期噛み
合い状態になり、その後尾栓２０を回転させると
第５図に示すように尾栓２０を完全に装着するこ
とができる。 In this embodiment as well, when the tail plug 20 is pushed a little harder against the general outer circumference 11, the thread 13 of the shaft cylinder 10
The tip end is the incompletely threaded portion 2 of the thread 22 of the tail plug 20
4, the tail plug 20 can be completely attached as shown in FIG. 5 by rotating the tail plug 20 after it reaches the initial engaged state as shown in FIG.
なお、前記実施例では、ねじ山を低くすること
により不完全ねじ部を形成したが、要するに押込
んだときの抵抗を少なくして乗り越えるようにす
ればよいので、ねじの始端部のねじ山を途切れ途
切れに切り欠いて抵抗を少なくして他方のねじ山
が乗り越え易くしてもよい。 In the above example, the incomplete threaded portion was formed by lowering the thread, but in short, it is sufficient to reduce the resistance when pushing in to overcome the problem. It may be cut out intermittently to reduce resistance and make it easier for the other thread to get over.
また、軸筒と端部部材との両方に不完全ねじ部
を設けてもよく、尾栓に限らず、先軸等の装着に
も適用でき、雄ねじと雌ねじとの勝手を変えても
よいことはいうまでもない。 In addition, incomplete threads may be provided on both the barrel and the end member, and the application is applicable not only to tail plugs but also to attachment of tip shafts, etc., and the orientation of the male and female threads may be changed. Needless to say.

の稼動率を下げることがない。"Effect of the invention" According to the mounting structure of the end member of a writing instrument according to the present invention, when the end member is attached to the barrel, it can be reliably temporarily attached, so that the end member may fall off inadvertently. There is no confusion in the process, and there is no reduction in the operating rate of the automatic process.
