て、グリップ部材５の部分を可撓性を備えた軟化状態に
する。Next, the use of the writing implement 1 of this embodiment will be described. Prior to use, the grip member 5 is given an appropriate deformation by, for example, denting a portion where a finger is to be placed so as to conform to the way the user holds the pen in the following procedure. (1) First, the writing implement 1 is set to, for example, 7
The grip member 5 of the writing instrument 1 is immersed in hot water heated to about 0 to 75 ° C. for a while, and the grip member 5 of the writing instrument 1 is heated to a softening temperature, so that the grip member 5 is in a softened state having flexibility.

る。(2) Next, by holding the heated writing instrument 1 while holding the grip as in a normal use state, the grip member 5 is appropriately deformed and then cooled to a softening temperature or lower and deformed. Fix the state. As a result, the gripping member 5 is dented at the position where the user's finger is arranged, and the writing implement 1 deformed into a shape optimal for the gripping state of the user is completed.

されているので、握り易く、書いていても疲れ難く、非
常に使用し易いものである。The subsequent use of the writing implement 1 is performed by grasping it according to the unevenness of the grip portion, similarly to the conventional writing implement 1. Since the grip member 5 is deformed into a shape peculiar to the user, it is easy to grasp, hard to be tired even when writing, and very easy to use.
【００１４】また、グリップ部に指のおく位置が凹凸状

のやり直しは適宜行うことができる。Further, since the position of the finger on the grip portion is shown in an uneven shape, it can be used for teaching a child how to hold a pencil. By the way, the grip member 5
Is of a shape memory type that can be restored to the original state by warming again to the softening temperature, so that the deformation can be repeated.
【００１５】なお、この発明の筆記具１は、上記実施例

先端グリップ部に直接的に、グリップ部材５を嵌め込ん
で装着する構成としてもよい。The writing instrument 1 of the present invention is not limited to the configuration of the above embodiment, but can be changed as appropriate. For example, in the above-described embodiment, the configuration in which the groove-shaped reduced diameter portion 22 is formed on the outer shaft 2 of the writing instrument 1 and the grip member 5 is disposed thereon has been described. Instead, the grip member 5 may be directly fitted into the tip grip portion of the writing instrument and mounted.

グリップ部材５を任意の筆記具１に装着して使用するこ
とができる。例えば、鉛筆等にも適用可能である。In the above embodiment, the outer shaft 2 of the writing implement 1 is used.
Although the configuration in which the grip member 5 is fixedly provided in advance has been described, the grip member 5 may be configured to be detachable from the writing instrument 1. That is, only the grip member 5 may be distributed alone or in circulation. In this case, the user
The grip member 5 can be attached to any writing implement 1 and used. For example, the present invention can be applied to a pencil and the like.

となる。Further, in the above-described embodiment, the configuration in which only the grip portion of the writing implement 1 is deformed has been described. However, the entire outer shaft 2 of the writing implement 1 may be configured to be curved. That is, the outer shaft 2 itself may be formed of the thermoplastic resin, and in addition to the deformation of the grip portion, the entire writing instrument 1 may be used by being curved and deformed into an easy-to-use shape. In this case, the writing instrument is particularly easy to use for elderly people with weak hand.
