　ところで、従来の筆記具では、予め筆記具本体が一体形成されている構成のものが一般的であり、文字などを書くための用途でしかなかった。すなわち、従来の筆記具では、本来の筆記機能だけを有しており、使用者の好奇心や遊び心を刺激する工夫がされているものは存在しなかった。 By the way, a conventional writing instrument generally has a configuration in which a writing instrument main body is integrally formed in advance, and is only used for writing characters and the like. That is, the conventional writing instruments have only the original writing function, and there has been no device that is devised to stimulate the user's curiosity and playfulness.
　そこで、本発明は、上記問題に鑑み、本来の筆記機能に加え、使用者の好奇心や遊び心を刺激することができる組立式筆記具を提供することを目的とする。 Therefore, in view of the above problems, an object of the present invention is to provide an assembly-type writing instrument that can stimulate the curiosity and playfulness of the user in addition to the original writing function.
　本発明は、軸筒部と、前記軸筒部の内部に収容される芯部と、を有する組立式筆記具であって、前記軸筒部は、複数の部品が相互に組み合わされて構成されていることを特徴とする。 The present invention is an assembly-type writing instrument having a shaft tube portion and a core portion housed in the shaft tube portion, and the shaft tube portion is configured by combining a plurality of components. It is characterized by being.
　この場合、複数の前記部品の結合のうち少なくとも一部の前記部品同士の結合は、相互に組み合わされた状態で相互に力が作用し合うことにより維持されていることが好ましい。 In this case, it is preferable that at least some of the parts among the plurality of parts are maintained by mutual force acting in a state of being combined with each other.
　この場合、複数の前記部品の結合のうち少なくとも一部の前記部品同士の結合は、軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されていることが好ましい。 In this case, at least some of the parts among the plurality of parts are joined together by utilizing the action / reaction of forces acting on each other in the axial direction and the direction orthogonal to the axial direction. Preferably it is.
　この場合、相互に結合される前記部品の少なくとも一方は、組み合わせる際に所定の弾性変形量だけ弾性変形され、所定の歪が生じた状態で係合していることが好ましい。 In this case, it is preferable that at least one of the parts to be coupled to each other is elastically deformed by a predetermined elastic deformation amount when being combined, and is engaged in a state where a predetermined strain is generated.
　この場合、複数の前記部品は、各々の前記部品が前記軸筒部の軸方向に沿った所定の位置で位置決めが可能となるように相互に接触していることが好ましい。 In this case, it is preferable that the plurality of parts are in contact with each other so that each of the parts can be positioned at a predetermined position along the axial direction of the shaft tube portion.
　本発明によれば、軸筒部と、前記軸筒部の内部に収容される芯部と、を有し、前記軸筒部は、複数の部品が相互に組み合わされて構成されているため、各部品を適宜組み合わせて軸筒部が作製される。これにより、使用者は、先ず軸筒部を作製する必要があり、あたかもプラモデルやブロックなどを組み立てるようにして組立式筆記具を作製する。この結果、使用者の好奇心や遊び心を刺激することができる。 According to the present invention, it has a shaft tube portion and a core portion accommodated inside the shaft tube portion, and the shaft tube portion is configured by combining a plurality of components. A shaft cylinder part is produced by appropriately combining the components. As a result, the user first needs to produce the shaft tube portion, and produces an assembly-type writing instrument as if assembling a plastic model or a block. As a result, the user's curiosity and playfulness can be stimulated.
　また、複数の前記部品の結合のうち少なくとも一部の前記部品同士の結合は、相互に組み合わされた状態で相互に力が作用し合うことにより維持されているので、容易に分離することを防止できる。 In addition, since at least some of the parts among the plurality of parts are joined with each other in a state of being combined with each other, the separation of the parts is prevented. it can.
　また、複数の前記部品の結合のうち少なくとも一部の前記部品同士の結合は、軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されていることにより、各部品は、２軸方向に対して相互に力を及ぼし合う。これにより、各部品が強固に固定される。 In addition, at least some of the parts among the plurality of parts are joined together by utilizing the action and reaction of forces acting on each other in the axial direction and the direction orthogonal to the axial direction. Thereby, each component exerts a force on each other in the biaxial direction. Thereby, each component is firmly fixed.
　また、相互に結合される前記部品の少なくとも一方は、組み合わせる際に所定の弾性変形量だけ弾性変形され、所定の歪が生じた状態で係合しているため、部品の結合力を一層高めることができる。 Further, since at least one of the parts to be coupled to each other is elastically deformed by a predetermined elastic deformation amount when being combined and engaged in a state in which the predetermined strain is generated, the coupling force of the parts is further increased. Can do.
　また、複数の前記部品は、各々の前記部品が前記軸筒部の軸方向に沿った所定の位置で位置決めが可能となるように相互に接触しているため、各部品を全て組み立てたときに一部の部品だけが軸方向に位置ずれしてしまうことを防止できる。これにより、組立式筆記具の組立完成度を高めることができる。 The plurality of parts are in contact with each other so that the parts can be positioned at predetermined positions along the axial direction of the shaft cylinder portion. Only a part of the components can be prevented from being displaced in the axial direction. Thereby, the assembly perfection degree of an assembly-type writing instrument can be raised.

　本発明の一実施形態に係る組立式筆記具について、図面を参照して説明する。なお、本実施形態では、筆記具の一例として、シャープペンシルを例にとり説明するが、本発明は、万年筆、鉛筆、ボールペンなど他の筆記具に適用することも可能である。 An assembly-type writing instrument according to an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a mechanical pencil will be described as an example of a writing instrument. However, the present invention can also be applied to other writing instruments such as a fountain pen, pencil, and ballpoint pen.
　図１に示すように、組立式筆記具１０は、軸筒部１２と、軸筒部１２の内部に収容される芯部１４と、を有し、軸筒部１２は、複数の部品１２ａ、１２ｂ、……が相互に組み合わされて構成されている。 As shown in FIG. 1, the assembly-type writing instrument 10 has a shaft tube portion 12 and a core portion 14 accommodated in the shaft tube portion 12, and the shaft tube portion 12 includes a plurality of components 12a and 12b. , ... are combined with each other.
　詳細には、複数の部品１２ａ、１２ｂ、…の結合は、相互に組み合わされた状態で相互に力が作用し合うことにより維持されている。具体的には、部品１２ａ、１２ｂ、…には、適宜、凸部又は凹部が形成されており、隣接する部品同士の凸部と凹部（あるいは凸部同士）とが係合している。このため、隣接する部品が相互に組み合わされた状態から組み合わせを解除する場合には、凸部と凹部との係合（凸部と凸部との係合）を解除しなければならず、各部品が容易に分離してしまうことを防止できる。 More specifically, the coupling of the plurality of parts 12a, 12b,... Is maintained by mutual force acting in a state of being combined with each other. Specifically, the parts 12a, 12b,... Are appropriately formed with convex portions or concave portions, and the convex portions and the concave portions (or the convex portions) of adjacent components are engaged with each other. For this reason, when releasing the combination from the state where adjacent parts are combined with each other, the engagement between the convex portion and the concave portion (engagement between the convex portion and the convex portion) must be released. It is possible to prevent parts from being easily separated.
　なお、複数の部品１２ａ、１２ｂ、…の結合のうち、全ての部品同士が結合において、互に組み合わされた状態で相互に力が作用し合うことにより維持されているわけではなく、少なくとも一部の部品同士の結合だけが、相互に組み合わされた状態で相互に力が作用し合うことにより維持されている構成でもよい。 It should be noted that, among the couplings of the plurality of parts 12a, 12b,..., All the parts are not maintained by the force acting on each other in the combined state. A configuration in which only the coupling of the components is maintained by mutual force acting in a combined state.
　また、複数の部品１２ａ、１２ｂ、…の結合は、軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されている。具体的には、隣接する部品同士の結合は、軸方向及び軸方向に対して直交する方向に、相互に力を作用し合って維持される。このとき、部品同士の凸部や凹部（あるいは凸部同士）が適宜係合されていることが好ましい。このように、各部品は、２軸方向に対して相互に力を及ぼし合うことにより、強固に固定されている。 Moreover, the coupling | bonding of several components 12a, 12b, ... is maintained using the effect | action and reaction of the force which interacts with respect to the direction orthogonal to an axial direction and an axial direction. Specifically, the coupling between adjacent parts is maintained by applying a force to each other in the axial direction and the direction orthogonal to the axial direction. At this time, it is preferable that the convex part and recessed part (or convex parts) of components are suitably engaged. In this way, each component is firmly fixed by exerting a force on each other in the biaxial direction.
　なお、複数の部品１２ａ、１２ｂ、…の結合のうち、全ての部品同士が結合において、軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されているわけではなく、少なくとも一部の部品同士の結合だけが、軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されている構成でもよい。 In addition, among the coupling | bonding of several components 12a, 12b, ..., all components are maintained using the effect | action / reaction of the force which interacts with respect to the direction orthogonal to an axial direction and an axial direction in coupling | bonding. However, the configuration may be such that only the coupling of at least some of the components is maintained by utilizing the action / reaction of forces that interact with each other in the axial direction and the direction orthogonal to the axial direction.
　また、複数の部品１２ａ、１２ｂ、…の少なくとも一方は、組み合わせる際に所定の弾性変形量だけ弾性変形させ、相互に組み合わされた状態では各部品が相互に力（応力）を作用し合って組み合わされる際の弾性変形量よりも小さな弾性変形量の弾性変形が維持されている。すなわち、隣接する部品の一方又は／及び両方は、所定の歪が生じた状態で相互に組み合っている。このため、隣接する部品が相互に組み合わされた状態において、隣接する部品の一方又は／及び両方には、所定の歪エネルギが蓄積されている。この結果、隣接する部品が相互に組み合わされた状態から組み合わせを解除する場合には、歪エネルギよりも大きなエネルギ（力）を各部品に作用させなければならず、各部品が容易に分離してしまうことを防止できる。 In addition, at least one of the plurality of parts 12a, 12b,... Is elastically deformed by a predetermined elastic deformation amount when being combined, and in a state where they are combined with each other, the parts act on each other by applying force (stress) to each other. The elastic deformation of the elastic deformation amount smaller than the elastic deformation amount at the time of being maintained is maintained. That is, one or / and both of the adjacent parts are assembled with each other in a state where a predetermined strain is generated. For this reason, in a state where adjacent parts are combined with each other, predetermined strain energy is accumulated in one or / and both of the adjacent parts. As a result, when the combination is released from the state where adjacent parts are combined with each other, energy (force) larger than the strain energy must be applied to each part, and each part can be easily separated. Can be prevented.
　なお、全ての部品が隣接する部品との間で、所定の歪が生じた状態で相互に組み合っている構成に限られず、一部の部品のみが隣接する部品との間で、所定の歪が生じた状態で相互に組み合っている構成を採用してもよい。 It should be noted that all parts are not limited to a configuration in which a predetermined distortion is generated between adjacent parts, and a predetermined distortion is generated only between some parts adjacent to each other. You may employ | adopt the structure mutually combined in the produced state.
　複数の部品１２ａ、１２ｂ、…は、相互に軸筒部１２の軸方向に沿った所定の位置で位置決めが可能となるように相互に接触している。具体的には、隣接する各部品には、各部品が相互に接触するための接触面が形成されている。そして、当該接触面において各部品が接触することにより、軸筒部１２の軸方向に沿った所定の位置で各部品が位置決め可能になる。このように、隣接する部品同士が軸方向に沿って位置決めされながら順次組み立てられていくため、全ての部品を組み立てたときに、一部の部品だけが軸方向に位置ずれしてしまうことを防止できる。この結果、組立式筆記具１０の組立完成度を高めることができ、使い勝手や意匠性を高めることができる。 The plurality of parts 12 a, 12 b,... Are in contact with each other so that they can be positioned at predetermined positions along the axial direction of the axial tube portion 12. Specifically, a contact surface for each component to contact each other is formed in each adjacent component. And when each component contacts on the said contact surface, each component can be positioned in the predetermined position along the axial direction of the axial cylinder part 12. FIG. In this way, since adjacent parts are sequentially assembled while being positioned along the axial direction, when all the parts are assembled, only a part of the parts is prevented from being displaced in the axial direction. it can. As a result, the degree of assembly completion of the assembly-type writing instrument 10 can be increased, and the usability and design can be improved.
　次に、本実施形態の組立式筆記具１０の組立方法の一例を詳細に説明する。なお、以下の組立方法は、一例に過ぎないものであり、本発明が以下の一例に限定されるものではない。 Next, an example of an assembly method for the assembly-type writing instrument 10 of the present embodiment will be described in detail. The following assembling method is only an example, and the present invention is not limited to the following example.
（第１組立工程）
　図２に示すように、第１部品１２ａを第２部品１２ｂにはめ込み、第１結合体１６（図３参照）を得る。このとき、第１部品１２ａの凸部１２ａ１が第２部品１２ｂの凹部１２ｂ１に挿入するようにして、第１部品１２ａを第２部品１２ｂにスライドさせる。そして、第１部品１２ａの凸部１２ａ１の先端部（接触部）と第２部品１２ｂの凹部１２ｂ１の底面部（接触部）とが当接して、第１部品１２ａのスライドが停止する。これにより、第１部品１２ａが第２部品１２ｂによって軸筒部１２の軸方向及び軸方向に直交する方向に沿って位置決めされる。その後、第１部品１２ａの２つの凸部１２ａ２、１２ａ３の間隔を広げるように弾性変形させて、２つの凸部１２ａ２、１２ａ３を第２部品１２ｂの凸部１２ｂ２の両側にはめ込む。 (First assembly process)
As shown in FIG. 2, the first component 12a is fitted into the second component 12b to obtain the first combined body 16 (see FIG. 3). At this time, the first part 12a is slid onto the second part 12b so that the convex part 12a1 of the first part 12a is inserted into the concave part 12b1 of the second part 12b. And the front-end | tip part (contact part) of the convex part 12a1 of the 1st component 12a and the bottom face part (contact part) of the recessed part 12b1 of the 2nd component 12b contact | abut, and the slide of the 1st component 12a stops. Thereby, the 1st component 12a is positioned along the direction orthogonal to the axial direction and axial direction of the axial cylinder part 12 by the 2nd component 12b. Thereafter, the two convex portions 12a2 and 12a3 are elastically deformed so as to widen the distance between the two convex portions 12a2 and 12a3 of the first component 12a, and the two convex portions 12a2 and 12a3 are fitted on both sides of the convex portion 12b2 of the second component 12b.
（力学的な説明）　
　このように、第１部品１２ａと第２部品１２ｂとは、第１部品１２ａの２つの凸部１２ａ２、１２ａ３と第２部品１２ｂの凸部１２ｂ２とが相互に力が作用し合うことにより、結合維持されている。第１部品１２ａと第２部品１２ｂの結合は、各々の凸部（あるいは凹部）において軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されている。具体的には、第１部品１２ａの２つの凸部１２ａ２、１２ａ３と第２部品１２ｂの凸部１２ｂ２との間には、組立後においても、所定の弾性力が作用している。そして、第１部品１２ａの２つの凸部１２ａ２、１２ａ３には、組立後も、組み付ける際よりも小さい弾性変形量の弾性変形が維持されている。このため、組立後においても、第１部品１２ａの２つの凸部１２ａ２、１２ａ３には、歪が発生しており、所定の歪エネルギが蓄積されている。 (Mechanical explanation)
As described above, the first component 12a and the second component 12b are coupled by the force acting between the two convex portions 12a2 and 12a3 of the first component 12a and the convex portion 12b2 of the second component 12b. Maintained. The coupling between the first component 12a and the second component 12b is maintained by utilizing the action / reaction of forces that interact with each other in the axial direction and the direction orthogonal to the axial direction at each convex portion (or concave portion). Yes. Specifically, a predetermined elastic force acts between the two convex portions 12a2 and 12a3 of the first component 12a and the convex portion 12b2 of the second component 12b even after assembly. The two convex portions 12a2 and 12a3 of the first component 12a maintain the elastic deformation with a smaller elastic deformation amount after assembly than after assembly. For this reason, even after assembly, the two convex portions 12a2 and 12a3 of the first component 12a are distorted, and predetermined strain energy is accumulated.
（第２組立工程）
　図３に示すように、第１結合体１６に第３部品１２ｃをはめ込み、第２結合体１８（図４参照）を得る。このとき、第１結合体１６の軸方向一方側に形成された凸部１６ａ１の先端面に凸が形成されており、当該凸が第３部品１２ｃの凸部１２ｃ１の端面に形成された凹に係合するようにはめ込む。なお、凸は、第１結合体１６を構成する第１部品１２ａ又は第２部品１２ｂに形成されている。これにより、第１結合体１６の接触部と第３部品１２ｃの接触部とが当接し、第１結合体１６が第３部品１２ｃによって軸筒部１２の軸方向及び軸方向に直交する方向に沿って位置決めされる。その後、第１結合体１６の２つの凸部１６ａ２、１６ａ３の間隔を広げて両者を弾性変形させ、第３部品１２ｃの凸部１２ｃ２の両側にはめ込む。 (Second assembly process)
As shown in FIG. 3, the 3rd component 12c is inserted in the 1st coupling body 16, and the 2nd coupling body 18 (refer FIG. 4) is obtained. At this time, a convex is formed on the tip surface of the convex portion 16a1 formed on one side in the axial direction of the first combined body 16, and the convex is formed in a concave formed on the end surface of the convex portion 12c1 of the third component 12c. Fit to engage. The protrusions are formed on the first component 12a or the second component 12b constituting the first combined body 16. Thereby, the contact part of the 1st coupling body 16 and the contact part of the 3rd component 12c contact | abut, and the 1st coupling body 16 is the direction orthogonal to the axial direction and axial direction of the axial cylinder part 12 by the 3rd component 12c. Positioned along. After that, the distance between the two convex portions 16a2 and 16a3 of the first combined body 16 is widened to elastically deform them, and is fitted on both sides of the convex portion 12c2 of the third component 12c.
（力学的な説明）
　このように、第１結合体１６と第３部品１２ｃとは、各々の凸部同士が相互に力が作用し合うことにより、結合維持されている。第１結合体１６と第３部品１２ｃの結合は、各々の凸部（あるいは凹部）において軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されている。具体的には、第１結合体１６の２つの凸部１６ａ２、１６ａ３と第３部品１２ｃの凸部１２ｃ２との間には、組立後においても、所定の弾性力が作用している。そして、第１結合体１６の２つの凸部１６ａ２、１６ａ３には、組立後も、組み付ける際よりも小さい弾性変形量の弾性変形が維持されている。このため、組立後においても、第１結合体１６の２つの凸部１６ａ２、１６ａ３には、歪が発生しており、所定の歪エネルギが蓄積されている。 (Mechanical explanation)
In this way, the first combined body 16 and the third component 12c are maintained in a coupled state by the forces acting on each convex portion. The connection between the first combined body 16 and the third component 12c is maintained by utilizing the action / reaction of forces that interact with each other in the axial direction and the direction orthogonal to the axial direction at each convex part (or concave part). ing. Specifically, a predetermined elastic force acts between the two convex portions 16a2 and 16a3 of the first combined body 16 and the convex portion 12c2 of the third component 12c even after assembly. And the two convex parts 16a2 and 16a3 of the 1st coupling body 16 are maintaining the elastic deformation of the elastic deformation amount smaller than the time of an assembly | attachment after an assembly. For this reason, even after the assembly, strain is generated in the two convex portions 16a2 and 16a3 of the first combined body 16, and predetermined strain energy is accumulated.
（第３組立工程）
　図４に示すように、第２結合体１８に第４部品１２ｄをはめ込み、第３結合体２０（図５参照）を得る。このとき、第２結合体１８の２つの凸部１８ａ１、１８ａ２の間隔を押し広げて両者を弾性変形させ、第２結合体１８の２つの凸部１８ａ１、１８ａ２の間に、第４部品１２ｄの凸部１２ｄ１を圧入する。さらに、このとき、第４部品１２ｄの凸が第２結合体１８の凹に係合するように調整する。これにより、第４部品１２ｄが第２結合体１８によって軸筒部１２の軸方向及び軸方向に直交する方向に沿って位置決めされる。 (Third assembly process)
As shown in FIG. 4, the 4th component 12d is inserted in the 2nd coupling body 18, and the 3rd coupling body 20 (refer FIG. 5) is obtained. At this time, the distance between the two convex portions 18a1 and 18a2 of the second combined body 18 is expanded and elastically deformed, and the fourth component 12d is interposed between the two convex portions 18a1 and 18a2 of the second combined body 18. The convex portion 12d1 is press-fitted. Further, at this time, adjustment is made so that the convex of the fourth component 12 d is engaged with the concave of the second combined body 18. As a result, the fourth component 12d is positioned by the second combined body 18 along the axial direction of the axial tube portion 12 and the direction orthogonal to the axial direction.
（力学的な説明）
　このように、第２結合体１８と第４部品１２ｄとは、各々の凸部同士が相互に力が作用し合うことにより、結合維持されている。第２結合体１８と第４部品１２ｄの結合は、各々の凸部（あるいは凹部）において軸方向及び軸方向に直交する方向に対して相互に作用する力の作用・反作用を利用して維持されている。具体的には、第２結合体１８の２つの凸部１８ａ１、１８ａ２と第４部品１２ｄの凸部１２ｄ１との間には、組立後においても、所定の弾性力が作用している。そして、第２結合体１８の２つの凸部１８ａ１、１８ａ２には、組立後も、組み付ける際よりも小さい弾性変形量の弾性変形が維持されている。このため、組立後においても、第２結合体１８の２つの凸部１８ａ１、１８ａ２には、歪が発生しており、所定の歪エネルギが蓄積されている。 (Mechanical explanation)
In this way, the second combined body 18 and the fourth component 12d are maintained in connection with each other by the forces acting on each other. The coupling between the second combined body 18 and the fourth component 12d is maintained by utilizing the action / reaction of forces that interact with each other in the axial direction and the direction orthogonal to the axial direction at each convex part (or concave part). ing. Specifically, a predetermined elastic force acts between the two convex portions 18a1 and 18a2 of the second combined body 18 and the convex portion 12d1 of the fourth component 12d even after assembly. The two convex portions 18a1 and 18a2 of the second combined body 18 maintain the elastic deformation with an elastic deformation amount smaller than that when assembled after the assembly.

（第２１組立工程）
　図２２に示すように、第１９結合体５２に第２１部品１２ｕをはめ込み、第２０結合体５４（図２３参照）を得る。このとき、第２１部品１２ｕの穴に口金１４ｆの先端部を通してはめる。その後、第２１部品１２ｕをつまんで、第２１部品１２ｕを所定の回転角度だけ回転させる。これにより、第２１部品１２ｕが第１９結合体５２に固定される。なお、第２１部品１２ｕは、軸筒部１２の先端部を構成する各部品を束ねる機能を兼ねる。 (21st assembly process)
As shown in FIG. 22, the 21st component 12u is inserted in the 19th coupling body 52, and the 20th coupling body 54 (refer FIG. 23) is obtained. At this time, the tip of the base 14f is inserted into the hole of the 21st component 12u. Thereafter, the 21st component 12u is pinched and the 21st component 12u is rotated by a predetermined rotation angle. As a result, the twenty-first component 12u is fixed to the nineteenth combined body 52. The twenty-first component 12u also has a function of bundling the components constituting the tip portion of the shaft tube portion 12.
　第２１組立工程では、軸筒部１２の大部分が完成された第１９結合体５２に第２１部品１２ｕをはめ込む工程であるが、第１９結合体５２が複数の部品が組み合わせられて構成されているにもかかわらず、第１９結合体５２の先端部を構成する各部品の少なくとも一部が軸方向に位置ずれしていない。具体的には、第１９結合体５２の先端部の一部だけが突出していない。これは、各部品が軸筒部１２の軸方向に位置決めされながら組み立てられたことにより、実現されている。この結果、第２１部品１２ｕを第１９結合体５２に容易にはめ込むことができ、組立式筆記具１０の組立完成度及び意匠性を高めることができる。 The twenty-first assembly step is a step of fitting the twenty-first component 12u into the nineteenth combined body 52 in which most of the shaft cylinder portion 12 is completed. The nineteenth combined body 52 is configured by combining a plurality of components. Nevertheless, at least a part of each component constituting the tip of the nineteenth combined body 52 is not displaced in the axial direction. Specifically, only a part of the tip of the nineteenth combined body 52 does not protrude. This is realized by assembling each component while being positioned in the axial direction of the shaft cylinder portion 12. As a result, the twenty-first component 12u can be easily fitted into the nineteenth combined body 52, and the degree of assembly completion and design of the assembling-type writing instrument 10 can be improved.
