Description

また、前記クリップの後端部と弾性部との接線が、前記弾性部を下向き、且つ前記軸筒の軸線を紙面に対し垂直上としたとき、４５度以上であることを特徴とする。 Further, the tangent line between the rear end portion of the clip and the elastic portion is 45 degrees or more when the elastic portion is directed downward and the axis of the shaft cylinder is perpendicular to the paper surface.

本願発明の第３の構成によれば、前記クリップの後端部と弾性部との接線が、前記弾性部を下向き、且つ前記軸筒の軸線を紙面に対し垂直状としたとき、４５度以上、好ましくは５０度以上、９０度以下とすることで、ユーザーが弾性部を使用するときに、紙面とクリップとの接触を気にせずに使用することができる。 According to the third configuration of the present invention, when the tangent line between the rear end portion of the clip and the elastic portion faces the elastic portion downward and the axis of the shaft cylinder is perpendicular to the paper surface, it is 45 degrees or more. When the elastic part is used by the user, preferably 50 degrees or more and 90 degrees or less, the user can use it without worrying about the contact between the paper surface and the clip.
