Description
軸筒には、先口部材の裏面側で先口部材の先端近傍まで延在する拡張部が設けられ、この拡張部は、先口部材より軟質な材料により形成されていることを特徴とする。
従来にあっては、落下衝撃時に先口部材の先端口が破損する事態を回避するために、先口部材の先端口に円錐台形状の樹脂部品を嵌め込んだり、先口部材の先端口を肉厚にしたりしていたが、本発明では、軸筒の拡張部の先端を先口部材の先端口から突出させているので、筆記具の先端の破損を防止することができる。そして、落下時に先口部材の先端が破損し難いので、例えば、先口部材に、装飾性が高いメッキを利用することもできる。さらに、先口部材の先端が変形し難くなるので、リフィールの出し入れの際の作動が安定する。
Claims (1)
- 先端側に設けられた先口部材と、リフィールを収容可能な軸筒とを備え、リフィールを先端から出没可能な筆記具において、
前記軸筒には、前記先口部材の裏面側で前記先口部材の先端近傍まで延在する拡張部が設けられ、この拡張部は、前記先口部材より軟質な材料により形成され、
前記先口部材に形成された先端口から前記拡張部の先端を突出させたことを特徴とする筆記具。
