<P>PROBLEM TO BE SOLVED: To propose a mounting structure of a clip for a writing utensil that allows sure mounting of a clip with simple operation by using only an internally-mounted inner member without mounting a clip to a shaft barrel while holding the clip by screw-fitting between an inner member mounted inside the shaft barrel and another member such as a screw to be screw-fitted to the inner member. <P>SOLUTION: An inner cylinder 3 is provided with a fitting part 9 in which one width V is formed slightly larger than the width N of the short side of a mounting hole 7 of a clip 4 and the other width W in a direction orthogonal to the one width V is formed smaller than the width N of the short side of the mounting hole 7. The fitting part 9 is loosely fitted to the mounting hole 7 of the clip 4 such that the one width V of the fitting part 9 is arranged along the long side of the mounting hole 7. The inner cylinder 3 is rotated so as to bring both ends 9a, 9b of the one width V of the fitting part 9 into pressure contact with the inside parts 5c, 5d of a mounting piece 5 constituting the mounting hole 7, thereby mounting the clip 4 to a writing utensil cap 1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
