No. 9389). More specifically, a rod-shaped body guide member having a guide groove is inserted into an outer shaft having a spiral groove formed on an inner surface. In addition, the rod-shaped body guiding member includes:
A rod-shaped receiving member for gripping and moving the rod-shaped body (eraser) is arranged. And, in the rod-shaped body receiving member,
A projection is formed and screwed into the spiral groove via the guide groove. The inner diameter of the spiral groove and the outer diameter of the projection are substantially equal or the diameter of the projection is slightly smaller. In addition, in order to manufacture at low cost, each component is molded from a resin molded product.

Results in roundness. In particular, in the case of forming a spiral groove, for example, when releasing the mold after the completion of the molding, since a part of a mold generally called a core pin is pulled out while rotating, the rounded corner of the spiral groove occurs. I will. Outer shaft (spiral groove) rounded in this way
Attach an eraser to the rod-shaped receiving member (projection),
When erasing, the projection of the rod-shaped receiving member may fall out of the spiral groove depending on how the force is applied, or the rod-shaped receiving member may be eccentric in one direction and fall off. In some cases, the eraser would fall into the outer shaft due to falling off.

(Back) while sliding. The eraser M protrudes from the rear end of the spiral member 10 due to the rise of the rod-shaped body receiving member 13. Then, even when the eraser M is strongly pressed against the paper surface or the like at the time of erasing, the screwing projection 17 is urged to the spiral groove 14 by the bulging portion 18 (in the state of FIG. The eraser and the rod receiving member do not move. When writing, pressing the spiral member 10 or the rear end of the eraser M that has been drawn out causes a writing body such as a lead to protrude from the front end of the tip member 3 by the pressing operation.
