が好ましい。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fountain pen according to an embodiment of the present invention shown in FIGS. Incidentally, the embodiment of the water-based ballpoint pen is of course also possible. First, the shaft 1 includes a front shaft 1a, a center shaft 1b, and a rear shaft 1c, and a ring 2 is sandwiched between the center shaft 1b and the rear shaft 1c. The ring 2 projects slightly from the side surfaces of the center shaft 1b and the rear shaft 1c. A locking portion 7 is provided at the tip of the front shaft 1a, and the tail end of the rear shaft 1c is curved. Next, the cap 3 is provided with a locking portion 7
Is provided with an inner cap 6 which can be engaged, and a border 9 is fixed to the open end, and the border 9 and the inner cap 6 are fixed.
The ring fitting portion 4 is provided at a substantially intermediate position of the ring. The ring fitting portion 4 is formed by forming a flat portion at a required position on the curved inner surface of the cap 3 as shown in FIGS. It is set slightly smaller and slightly smaller than the outer diameter of the ring 2. The diameter of the inscribed circle at the ring fitting portion 4 is gradually reduced in the depth direction of the cap 3. That is, the ring fitting portion 4 is slightly inclined toward the back of the cap 3. The ring fitting portions 4 are provided at four locations at 90 ° intervals in the circumferential direction, but the spacing and number are arbitrary and may be provided over the entire circumference. Although the shape of the ring fitting portion 4 may be a protrusion, it is preferably a shape as in the above-described embodiment in which undercut does not occur on molding.

容範囲が広がって部品製造が容易化する有利がある。[Effect of the Invention] The present invention is as described above. A ring fitting portion is provided on the inner surface of the cap, and a ring attached to the shaft of the writing instrument body is pressed against the ring fitting portion to fix the cap to the shaft. As a result, it is not necessary to first install a spring component such as a wig inside the cap as in the conventional case, so that an increase in the number of components can be prevented. There is no need to provide a locking part that fits, which is advantageous in that the design of the rear end of the shaft is not restricted and can be made into a free shape.Furthermore, since the cap does not directly contact the side of the shaft, This has the effect of eliminating the possibility of scratching. In addition, if the ring fitting portion is inclined toward the back of the cap as in the above embodiment, even if there is some error in the outer diameter of the ring, the error is absorbed only by moving the fitting position back and forth. Since it is possible, the allowable range of the dimensional accuracy is widened, and there is an advantage that the manufacture of parts is facilitated.
