Not only did the cost of parts increase, but the man-hours required for assembly also increased, resulting in higher product prices. Therefore, a method of integrally forming the grip portion on the shaft body in a manner such as two-color molding has been adopted. However, in the writing instrument having the above-described configuration, the shaft is formed, and then, when the grip is formed, when the position of the mold for forming the grip is slightly shifted forward, The resin that forms the grip at the tip of the shaft leaks, which not only reduces the value of the product, but also the resin that leaks at the tip of the shaft has an adverse effect on the mounting work of the tip member. It had something to do.

Similarly, the same outer shape is formed at both ends of the reduced diameter portion 19 of the shaft cylinder 1 where the flat cylindrical portions 22 and 23 are in contact. In this example, the grip member 2 is used.
0, flat cylindrical portions are formed at the front and rear ends, and flat cylindrical portions are formed at both ends of the reduced diameter portion of the shaft cylinder 1. As shown in FIG. And the front end of the shaft cylinder 1 (the flange 1a) with which the front end contacts. More specifically, in this example, the grip member is not fitted into the reduced diameter portion (recess), but is formed so as to simply cover the surface of the barrel 1. However, a flange 1a is formed in front of the barrel 1 so that the front end surface of the grip member 20 contacts the outer periphery of the flange 1a. The outer shape of the flange 1a is the same as the outer shape of the front end cylinder 22 of the grip member 20. (Second example).

障をきたすことがない。Next, the operation will be described. The barrel 1 is formed, and then the grip member 20 is formed. At this time, even if the mold for forming the grip member 20 is slightly shifted forward, the front portion of the mold is reduced in diameter of the barrel 1. Part 19
The resin of the grip member 20 does not leak to the front of the shaft cylinder 1 because the position of the shaft member 1 is shifted. Here, even if the mold for forming the grip member 20 is displaced more than the reduced diameter portion 19, the front portion of the mold is located on the flange portion 1a of the barrel 1, so that the resin is It does not leak forward.
Incidentally, the molded product at this time becomes a molded product as shown in FIG. 7, and does not hinder the assembling work in the next step.

The joint member 10 for fixing the lead-out mechanism 2 to the barrel 1 can be hidden inside the barrel 1, thereby improving the appearance and improving the appearance of the pipe. The concave portions caused by the cooling shrinkage, which are generated at the time of forming the flesh portion, are prevented by forming the thin portion. A conical portion 25 is formed on a front inner surface of the reduced diameter portion 19 of the shaft cylinder 1 so as to gradually expand forward.
), A rib 26 having an inclined surface instead of the conical portion 25.
(See FIG. 7). The conical portion 25 and the rib 26 are formed near the large diameter portion 24. The strength of the front portion of the barrel 1 is improved, and the strength is improved.
Damage when detached from the mold, for example, separation of the flange portion 1a from the barrel 1 can be prevented.

る（第３例）。A third example will be described with reference to FIG. In this example, at least one end of the grip member 20, in this example, the front end is intentionally slightly covered with the flange 1 a of the barrel 1 (the front end covering portion 27). Also in this example, since the collar portion 1a is formed on the barrel 1, even if the mold forming the grip member 27 is slightly shifted, the resin of the grip member 27 leaks to the front end of the barrel 1. Nothing. As shown in FIG. 9, the rear end of the grip member 20 may also be covered with the shaft cylinder 1 (the rear end covering portion 28).
By increasing the coating amount of 7, 28, it is possible to mold a product having almost the same appearance even if the positioning accuracy of the mold for molding the grip member is somewhat poor (third example).
