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。回転子の軸方向の一端面および他端面に第１と第２のカム面（６ａ），（６ｂ）がそれぞれ形成されると共に、前記第１と第２のカム面にそれぞれ対峙するように前記軸筒側に配置された第１と第２の固定カム面（１３ａ），（１４ａ）が具備されて筆記芯の回転駆動機構が形成されている。 　回転子の一部には楔形の切欠き部による表示部（６ｃ）が形成されており、これは透明な素材により形成された軸筒を介して視認することができる。この構成により、筆記圧により筆記芯が徐々に回転される動作を確実に把握することができるシャープペンシルが提供される。
