GRIP STRUCTURE OF SHAFT TUBE AND WRITING IMPLEMENT AND APPLYING IMPLEMENT PROVIDED WITH SUCH GRIP STRUCTURE OF SHAFT TUBE

摘要

A grip structure of a shaft tube, and a writing implement and an applying implement each of which has the grip structure in a shaft tube are provided to increase the adhesion of a gel material and a shaft, to improve the appearance of the shaft tube and to prevent the dullness of a grip color. A grip structure(20) of a shaft tube(11) includes an endothelial object(21) for covering a shaft(13) directly, which is installed at the outside of the shaft containing the coating material therein; an envelope object(23) for covering the outside of the endothelial object; and a material(25) with a gel state capable of self-configuration maintenance, which fills a space between the endothelial object and the envelope object. The endothelial object is formed of a material having higher compatibility with the gel matter than the material of the shaft. Preferably, the shaft is made of a metal, and the endothelial object is formed of a material with light impermeability. Each of a writing implement(10) and an applying implement is provided with the grip structure in a grasping section(17) of the shaft tube(11) containing a coating material.
