A rear shaft cylinder is fitted to the rear shaft cylinder so as to be movable in the axial direction behind the front shaft cylinder, and a spring is provided between the front shaft cylinder and the rear shaft cylinder to urge the rear shaft cylinder rearward, When the rear barrel is moved forward, an engagement portion is provided in the side knock member and the rear barrel so that the rear barrel is engaged with the side knock member, and the side knock member is pressed in the axial direction. At the same time, an extendable writing instrument is provided that is detachably provided so that the engagement portion is disengaged.
本発明は、上記のように構成されているので、通常の使用の際は、サイドノック部材を押圧して芯やレフィールを繰り出すことができ、不使用時や携行時には後部軸筒を前方に移動させると、上記サイドノック部材に設けた係合部と後部軸筒に設けた係合部が係合するので、該後部軸筒をその状態に保持して全長を短縮することができる。そして、使用に際して、上記のようにサイドノック部材を押圧すれば、芯やレフィールを繰り出すことができると共に後部軸筒の係合が外れて該後部軸筒は後方に移動し全長を長くすることができ、使いやすい。このように、本発明によれば、特別の解除ボタン等を設ける必要がなく、サイドノック部材で兼用することができるので、構成が簡単で操作が容易であり、経済的に得ることができる。 Since the present invention is configured as described above, in normal use, the side knock member can be pressed to feed out the core and refill, and the rear barrel can be moved forward when not in use or carried. By doing so, the engaging portion provided on the side knock member and the engaging portion provided on the rear shaft tube are engaged with each other, so that the rear shaft tube can be held in that state and the overall length can be shortened. In use, if the side knock member is pressed as described above, the core and refill can be fed out, and the rear shaft tube can be disengaged and the rear shaft tube can move rearward to lengthen the entire length. Easy to use. Thus, according to the present invention, there is no need to provide a special release button or the like, and the side knock member can also be used. Therefore, the configuration is simple, the operation is easy, and it can be obtained economically.
