つていた。(Problems to be solved by the invention) The above-mentioned writing instrument in which the rear outer side surface of the barrel and the inner side surface of the cap fit together cannot escape from the conventional image in terms of appearance, and may not be novel or unique compared to writing instruments. It has become difficult to provide a wide variety of exterior designs, and the creation of new designs has been subject to various restrictions.

成できないという問題があつた。 These scratch problems can be somewhat controlled by a writing instrument consisting of a cap with a mating part inside and a barrel with a mating part on the inside of the barrel, but When the cursive font is made of synthetic resin and is fixed to the barrel by screwing, new problems arise. In other words, columns and cylinders that are injection molded products of synthetic resin are
Variations occur in the center of the molded product, and a straight molded product cannot be obtained unless molding is performed with considerable precision. In particular, when it has a threaded part and is screwed onto another component, the assembled product may be off-center due to variations in the threaded part. In this case, if the fitting part for the fitting part of the cap is provided on a member that is offset from the center, the outside surface of the cap will be damaged by the opening of the barrel, making it impossible to achieve the original purpose. There was a problem.

取付けられている。 Figures 1 and 2 show an embodiment of the present invention, in which a shaft cylinder 11 made of metal such as aluminum is open at both ends and gradually reduces in diameter as it goes forward.
A ring-shaped core 12 is fixed to the inside of the front end. Between this core 12 and the front part of the shaft cylinder 11, the center shaft is a metal cylindrical member that has an inward flange 13a at the rear end and can be fitted into a cap 15, which will be described later. 13 is clamped and fixed by its front end. Reference numeral 14 is a writing body made of synthetic resin that has a writing part 14a at its tip and is detachable from the shaft tube 11.
A threaded portion 14b is formed approximately in the center of 4.
The writing body 14 is screwed and fixed to the shaft tube 11 through this screwing portion 14b. The rear end of this writing body 14 is placed inside the center shaft 13, so that only the tail plug 14c of the writing body 14 is exposed. Reference numeral 15 is a cap made of metal such as aluminum into which the writing body 14 can be fitted, and like the barrel 11, the diameter is gradually reduced toward the front. Inside cap 16 to airtight
is arranged, and an elastic side 17 such as a spring wig, which is a ring-shaped fitting part, is attached to the inner wall surface.

ある。 In the above configuration, when actually writing, it is sufficient to remove the cap 15 from the writing body 14 and insert the cap 15 with the open side of the cap 15 facing inside the rear end opening of the barrel 11. At this time, cap 1
The elastic side 17 (fitting part) inside the cap 15 slides into frictional engagement with the peripheral wall of the center shaft 13 (fitted part) disposed inside the shaft cylinder 11, and as a result, the shaft cylinder 11 of the cap 15
It is possible to fit the (See Figure 2) In this case, the outer surfaces of the barrel 11 and the cap 15 are prevented from sliding against each other, and even if the writing body 14 is eccentric, it can be absorbed by the center shaft. The surface of the cap will not be scratched and the rich luster of the metal will not be lost.Furthermore, since the shaft tube 11 and the cap 15 are not directly fitted, there is no dimensional difference between them. This has excellent practical advantages, such as flexibility in fitting accuracy even if there is some misalignment.
