PURPOSE: To allow a clip part fitted and secured relative to a writing utensil cap to have a sufficient drag with respect to the pulling out direction and rotating direction from the cap. CONSTITUTION: The second projection part 15e provided in the Inner wall surface in a clip securing base part 15A comes in the second tapered part 14e provided in the outer wall of a cap 14, and has a large drag relative to forces in the pulling out direction of the clip securing base part 15A. Also, a groove part 15h is given In the axial direction in a manner continuing from the first parallel part 15a of the clip securing base part 15 through the third parallel part 15, and with respect to the groove part 15h, a parallel part 14g is fitted which Is flush with the first parallel part 14a provided in a manner filling up the groove part 14b in the cap 14 side, thereby preventing a relative rotation between the cap 14 and the clip securing base part 15A. |
