【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a writing instrument of the present invention, FIG. 2 is an exploded partially broken perspective view of the same, FIG. 3 is a plan view of a cap, and FIG. 4 is a cross-sectional view of a cap. , A cap 20, and a decorative body 30 attached to the cap 20.

As shown in FIG. 1, the writing instrument main body 10 has a shaft portion 10 A having a substantially elliptic cylindrical shape with a flat cross section, and one end portion 11 of the writing instrument main body 10 is colored with each other for performing a writing function. Different ball-point pens 12 and 13 are supported by supporting cylinders 12a and 13a, and these ball-point pens 12 and 13 are arranged along the major axis direction to form a so-called two-color ball-point pen.

The end 11 where the support cylinders 12 a and 13 a that support the ball-point pens 12 and 13 are located has a reduced shape following the outer shape of the writing instrument body 10, and the writing instrument body 10 is surrounded by the end portion 11. The step portion 14 is formed between the shaft portion 10A and the shaft portion 10A, and functions as a stopper when the cap 20 described later is covered.

Therefore, since the writing instrument main body 10 and the cap 20 are formed of an elastic material typified by plastics, when the writing instrument main body 10 is covered with the cap 20, the writing instrument main body 10 is elastically coupled.

As shown in FIG. 2, the cap 20 is provided with two mounting holes 21 and 21 for mounting a decorative body 30 which will be described later on the top end portion thereof. Both ends of the locking rib 22 are formed integrally with the inner wall of the cap 20 so as to traverse the space.

One end surface 22 a of the locking rib 22 near the mounting hole 21 is an inclined surface along the shape of the top end portion of the cap 20, and the other end surface is a flat surface 22 b.

In addition, stepped portions 21 a are formed at both ends of the mounting hole 21 in the length direction, and the stepped portions 21 a are formed on both ends of the decorative piece 31 of the decorative body 30 by inserting the decorative body 30 which will be described later. The stopper 31a is mounted on the stepped portion 21a.
