Abstract

ノック機構を備えた筆記具において、外界から密閉されたダンパー空間を設けることにより、通常の動作を妨げずに衝撃緩衝作用を実現可能な筆記具を提供する。押し出し操作による筆記先端11の繰り出しが可能なノック機構を備えた筆記具10であって、筆記先端11を保持する保持部12と、前記保持部12を内包する軸筒20と、前記軸筒20の後端部分を被覆するノック部30と、前記ノック部30の押し出し操作に連動して前記保持部12を先端方向に押圧する押出部13とを備えるとともに、前記ノック部30と前記軸筒20との間に、外界から密閉され、かつ、同ノック部30の押し出し操作により容積が変化するダンパー空間40が設けられている。
