Abstract

　筆記芯を把持するチャック（４）と共に、軸筒（１）内において回転方向および軸方向に移動可能に構成された回転子（６）が具備されている。筆記動作に伴う回転子の軸方向の移動により回転子が回転し、筆記芯も回転運動を受ける。軸筒の後端部に配置されたノックカバー（２６）のノック操作によりチャックから筆記芯を繰り出させることができる。前記ノックカバーから前記チャックに至るノック操作の伝達経路のいずれかの箇所に、前記ノック操作を前記チャックに伝達し、回転動作が遮断されるギャップ（Ｇ）を有する切り離し部が形成されている。 　前記した構成により、回転子とノックカバーとは回転方向において分離されるので、回転駆動機構に障害を与える問題を解消することができる。
