Similarly, the upper body 50 and the central body 60 and the central body 60 and the lower body 70 can be easily attached and detached, and the second writing instrument 91 can be used. Further, the plug body 30 can be easily attached and detached.

An example of another function of the writing instrument will be described with reference to the drawings. The second central (through) storage hole 72 has a lower end portion for accommodating a second writing instrument 91 whose hole diameter is such that a part of the sound generator (whistle) 40 described below can be accommodated. It is larger than the upper part. The hole diameter of the enlarged lower end portion is formed to be substantially longer than the length of the insertion portion of the sound generator (whistle) 40, and the upper portion relatively thin as compared with the central storage (penetration) hole 72. The space portion 721 is communicated with the space.

The lower body 70 is provided with an opening 73 on a part of its side wall for outputting the sound from the sound generator (whistle) 40 to the outside. The opening 73 communicates with a space 721 provided above the lower end of the central storage (penetration) hole 72 into which the sound generator (whistle) 40 is inserted.

The sound generator (whistle) 40 generates a sound by the exhalation such as a whistle, and a lid 41 fixed to the bottom of the lower body 70 with an appropriate adhesive or the like, and a lid 41. The sound generating auxiliary tool 42 is inserted into the lower end of the central storage (through) hole 72 and the sound generating nozzle 43. In order to generate sound in cooperation with the auxiliary tool 42, the lid 41 has a ventilation hole of an appropriate size, and the sound generating nozzle has a structure for communicating the space 721 with the outside air. .. The lid 41 and the sound generation assisting tool 42 can be integrally formed.

The user of the sound generator 40 blows air into the space 721 through the sound generating nozzle 43. Then, the air is discharged to the outside through the opening 73 that communicates with the space 721, and at that time, a unique sound is generated by the sound generating means. Therefore, the writing instrument also functions as a call whistle.

FIG. 4 shows a writing instrument structure according to another embodiment of the present invention. The central body 60 according to this embodiment has an insertion hole 65 having a shape in which the extension receiving hole 633 further extends axially upward and penetrates the central body 60. In the sound generation assisting tool 42 of the preceding example, a storage hole 441 for storing the lower part of the main body of the second writing tool 91 is provided as an axial extension of the storage hole 72, and a part of the main body of the second writing tool 91 is attached. It can be stored and supported.

The insertion hole 65 has the tip 902 on the lower side and the tip 902 of the first writing instrument 90 stored in the central storage hole 52, the second central storage hole 72, and the storage hole 441. 2 The tip portion 912 of the writing instrument 91 is accommodated in a facing state. The present invention is not limited to the above-mentioned embodiment, and the concavo-convex shape, the number, the size, the material, etc. of each part may be appropriately changed without departing from the spirit of the present invention.
