CLIP STRUCTURE OF WRITING INSTRUMENT AND WRITING INSTRUMENT HAVING CLIP STRUCTURE

PROBLEM TO BE SOLVED: To provide a clip structure of a writing instrument which has a small load on an elastic member for making a clip generate clamping force, suppresses clip damage when clip opening exceeding assumption is performed, and enables the clip to obtain a substantially constant pinching force.SOLUTION: A clip body 4 of this clip structure has a base part 4b provided with a pressure contact part coming in pressure contact with an object to be pinched, a coupling part 4c extended rearward from the base part, a support object means 4d provided in the rear end part of the coupling part and supported to be rotatable by the support part, an elastic piece 4e one end part of which is coupled with the base part, and an engagement object part 4e1 formed at the rear end part of the elastic piece. A support part 3 of the mounting object body has an engagement part 3a that keeps the engagement object part engaged and releases engagement with the engagement object part 4e1 when a force of a predetermined deformation amount or more acts on the clip body 4 and a support means 3b that supports the clip body in a state of free rotation.SELECTED DRAWING: Figure 2 【課題】クリップに挟持力を発生させる弾性部材への負荷が小さく、想定を超えるクリップの開拡がなされた際にも、クリップの破損が抑制され、また、クリップに略一定の挟持力が得られる筆記具のクリップ構造を提供する。【解決手段】このクリップ構造のクリップ本体４は、被挟持物に圧接する圧接部が設けられた基部４ｂと、前記基部から後方に延設された連結部４ｃと、前記連結部の後端部に設けられ、前記支持部に回動自在に支持される被支持手段４ｄと、前記基部に一端部が連結された弾性片４ｅと、前記弾性片の後端部に形成された被係止部４ｅ１と、を有し、前記被取付け体の支持部３は、前記被係止部を係止状態になし、前記クリップ本体４に所定変形量以上の力が作用した際、前記被係止部４ｅ１との係止状態を解除する係止部３ａと、前記クリップ本体を回動自在状態に支持する支持手段３ｂと、を有する。【選択図】図２
