Zusammenfassung: | To provide a ball point pen which enables writing with a fine line width or a thick line width according to user's preferences and enables writing with a stable line width regardless of a writing angle.SOLUTION: A ball point pen includes: a barrel; a chip holder housed within the barrel; a chip which is attached to the chip holder in such a way so as to be movable forward and rearward; a ball held at a front end of the chip; an ink storage part cylinder which is disposed rearward of the chip and stores an ink; an outer cylindrical body which may move in an axial direction relative to the chip holder and tilt in the axial direction of the chip; a first bouncing member which bounces the outer cylindrical body forward when the outer cylindrical body is moved rearward relative to the chip holder; and a second bouncing member which is disposed rearward of the chip and bounces the chip forward. The ball forms a frist writing part and a second writing part is formed at a front end of the outer cylindrical body.SELECTED DRAWING: Figure 3
【課題】細い線幅と太い線幅での筆記を使い分けることができるとともに筆記角度によらず安定した線幅での筆記が可能なボールペンを提供すること。【解決手段】軸筒と、前記軸筒の内部に収容されたチップホルダーと、前記チップホルダーに対して前後動自在に装着されたチップと、前記チップの前方端において保持されたボールと、前記チップの後方に配置されインキを収容するインキ収容部筒と、前記チップホルダーに対して軸方向に相対移動可能、且つ、前記チップの軸方向に対して傾動可能な外筒体と、前記チップホルダーに対して当該外筒体が後退した際に当該外筒体を前方に弾発する第1弾発部材と、前記チップの後方に配置され当該チップを前方に弾発する第2弾発部材と、を備え、前記ボールが第1筆記部を構成すると共に、前記外筒体の前端に第2筆記部を形成する。【選択図】 図3 |
