記具６にがたつくことなく装着される。(Embodiment) The drawing shows an embodiment of the present invention, in which 1 is a spiral cylinder made of, for example, an elastic metal wire 2 and inserted into a writing instrument 6 such as a ballpoint pen, a sharpie pen, or a pencil; has a slightly larger diameter than the outer diameter of the writing instrument body 6a. The tip of the spiral cylinder 1 has a small diameter and forms a receiving portion 3 that engages with the tapered tip 7 of the writing instrument 6. 4 is the spiral cylinder body 1
A cap body made of metal, for example, which is fitted into the base end of the cylindrical part 4b with one end 4a closed, has a spiral groove 5 of the same pitch as the spiral pitch of the spiral cylinder body 1 formed on the inner surface of the cylindrical part 4b. By screwing and fitting the base end spiral 2a of the spiral cylinder body 1 into the spiral groove 5 on the inner surface of the cylindrical portion 4b while the inner surface of the closed end 4a is pressed against the writing instrument base end 6b. The spiral cylinder body 1 is elastically stretched between the distal end receiving portion 3 and the proximal end spiral 2a, and is attached to the writing instrument 6 without wobbling.

Further, the spiral tube body 1 and the cap body 4 can be made of transparent or opaque plastic materials, and patterns, colors, advertising characters, etc. can be arbitrarily displayed on the outer surfaces of the spiral tube body 1 and the cap body 4. can. Furthermore, the state in which the spiral cylinder body 1 is attached to the writing instrument 6 (second
The pitch between the wire rods (shown in the figure) is arbitrary, but the narrower the pitch, the smoother the feeling when gripping the wire.

（考案の効果） 本考案被覆体は伸縮するので内部に収容する筆
記具の長さに制限されずに使用できる。(Effects of the invention) Since the covering of the invention is expandable and contractible, it can be used without being limited by the length of the writing implement housed inside.
