发明名称 CLIPPING STRUCTURE FOR WRITING INSTRUMENT
摘要 A clipping structure includes a main body, a clip member, and an urging member for urging the clip member. The main body has a connecting protrusion, whereas the clip member has two lateral parts, between which the connecting protrusion is arranged. Further, the connecting protrusion has receptacles on its outer surfaces, whereas the lateral parts have shaft projections on its inner surfaces respectively. Fitting of the shaft projections into the respective receptacles connects the clipping member swingably to the main body. The connecting protrusion, where the receptacles are formed, has tapered portions formed on its outer surfaces respectively. Gradual opening of a gap between the lateral parts with distal ends of the shaft projections brought into contact with the respective tapered portions fits the shaft projections in the respective receptacles.
