＜第１の実施形態＞
　図１は、冷蔵庫１００の外観の一例を示す斜視図である。図１に示すように、冷蔵庫１００は、冷蔵庫１００本体と複数の扉１０１を有する。複数の扉１０１は、図１の扉１０１の左側の端部にハンドル１０２を有する。具体的には、ハンドル１０２は、図２に示すように、パイプ２０１とパイプキャップ２０２を有する。なお、当該ハンドル１０２は、冷蔵庫１００に用いられる場合に限定されず、種々の機器の扉１０１のハンドル１０２に適用してもよい。 <First Embodiment>
FIG. 1 is a perspective view showing an example of the appearance of the refrigerator 100. As shown in FIG. 1, the refrigerator 100 has a refrigerator 100 main body and a plurality of doors 101. The plurality of doors 101 has a handle 102 at the left end of the doors 101 in FIG. Specifically, as shown in FIG. 2, the handle 102 has a pipe 201 and a pipe cap 202. The handle 102 is not limited to being used in the refrigerator 100, and may be applied to the handle 102 of the door 101 of various devices.
　パイプ２０１は、内部が中空の矩形形状であって、扉１０１の一辺に沿って設けられる。パイプ２０１の長手方向の長さ２０３は、扉１０１の高さ方向の長さ１０３と、同等である。また、パイプ２０１は、例えば、アルミニウム等を用いて形成される。さらに、パイプ２０１は、冷蔵庫１００の扉１０１の一端に取り付けられる板状の冷蔵庫取り付け部２０４を有する。冷蔵庫取り付け部２０４は、扉１０１に取り付けるための、例えば複数の連結部材（図示なし）を通す複数の孔２０５を有する。また、パイプ２０１は、図２の上方及び下方に矩形形状の開口端部２０６を有する。パイプ２０１は、パイプキャップ２０２を固定する螺合部材２０７を通すための螺合部材受け止め孔２０８を有する。この螺合部材受け止め孔２０８は、パイプ２０１の図２の前面に設けられている。なお、パイプ２０１の断面形状は矩形形状に限られず、例えば、手をかけ易いように、凹んだ形状であってもよい。 The pipe 201 has a hollow rectangular shape and is provided along one side of the door 101. The length 203 of the pipe 201 in the longitudinal direction is equal to the length 103 of the door 101 in the height direction. The pipe 201 is formed using, for example, aluminum or the like. Further, the pipe 201 has a plate-shaped refrigerator mounting portion 204 mounted on one end of the door 101 of the refrigerator 100. The refrigerator mounting portion 204 has a plurality of holes 205 through which a plurality of connecting members (not shown) for mounting on the door 101 are inserted. Further, the pipe 201 has rectangular opening end portions 206 on the upper side and the lower side of FIG. The pipe 201 has a screw member receiving hole 208 for passing a screw member 207 that fixes the pipe cap 202. This screw member receiving hole 208 is provided on the front surface of the pipe 201 in FIG. The cross-sectional shape of the pipe 201 is not limited to the rectangular shape, and may be, for example, a recessed shape so that the hand can be easily placed.
　パイプキャップ２０２は、上記２つの開口端部２０６を塞ぐように、それぞれ取り付けられる。なお、パイプキャップ２０２は１つであってもよく、この場合、パイプキャップ２０２はパイプ２０１の１つの開口端部２０６のみを塞ぐように構成してもよい。パイプキャップ２０２の材料は、例えば、樹脂である。 The pipe caps 202 are attached so as to close the two open ends 206. The number of the pipe caps 202 may be one, and in this case, the pipe caps 202 may be configured to close only one open end 206 of the pipe 201. The material of the pipe cap 202 is resin, for example.
　つぎに、パイプキャップ２０２についてより具体的に説明する。図３は、パイプキャップ２０２の具体的構成の一例を示す図である。図４は、パイプキャップ２０２をパイプ２０１に取り付ける方法を示す斜視図である。図５は、パイプキャップ２０２がパイプ２０１に取り付けられた場合における、図４のＶ－Ｖ断面の概略図である。 Next, the pipe cap 202 will be described more specifically. FIG. 3 is a diagram showing an example of a specific configuration of the pipe cap 202. FIG. 4 is a perspective view showing a method of attaching the pipe cap 202 to the pipe 201. FIG. 5 is a schematic view of the VV cross section of FIG. 4 when the pipe cap 202 is attached to the pipe 201.
　図３に示すように、パイプキャップ２０２は、蓋部３０１と、固定部３０２と、浮き防止部３０３と、を有する。 As shown in FIG. 3, the pipe cap 202 has a lid portion 301, a fixing portion 302, and a floating prevention portion 303.
　蓋部３０１は、開口端部２０６を塞ぐ。具体的には、蓋部３０１は、例えば、開口端部２０６の外縁に沿った形状を有する。蓋部３０１は、例えば板状の形状を有する。なお、当該蓋部３０１の形状は一例であって、その他の形状であってもよい。 The lid 301 closes the open end 206. Specifically, the lid portion 301 has, for example, a shape along the outer edge of the opening end portion 206. The lid 301 has, for example, a plate shape. It should be noted that the shape of the lid portion 301 is an example, and may have other shapes.
　固定部３０２は、パイプキャップ２０２をパイプ２０１に固定する部位である。具体的には、固定部３０２は、例えば、板状の部材である。また、固定部３０２は、図３に示すように、蓋部３０１の底面３０４に対して略垂直に形成される。そして、固定部３０２は、例えば、パイプキャップ２０２をパイプ２０１に挿入したときに、パイプ２０１の外側の側面に沿う位置に形成される。 The fixing portion 302 is a portion that fixes the pipe cap 202 to the pipe 201. Specifically, the fixed portion 302 is, for example, a plate-shaped member. Further, the fixing portion 302 is formed substantially perpendicular to the bottom surface 304 of the lid portion 301, as shown in FIG. The fixing portion 302 is formed at a position along the outer side surface of the pipe 201 when the pipe cap 202 is inserted into the pipe 201, for example.
　さらに固定部３０２は、パイプキャップ２０２をパイプ２０１に固定する螺合部材２０７が挿入される開口孔である固定部開口孔３０５を有する。固定部開口孔３０５は、例えば固定部３０２の略中央部に設けられる。螺合部材２０７は、たとえば、ビス等であって、螺合部材２０７がパイプキャップ２０２の固定部開口孔３０５に通された後にパイプ２０１の螺合部材受け止め孔２０８に通される。螺合部材受け止め孔２０８には予め雌ねじが形成されている、もしくは螺合部材２０７の回転により螺合部材受け止め孔２０８に雌ねじ形状が形成されることで、螺合部材２０７の回転（本実施形態では時計回りの回転）により、螺合部材２０７は固定部開口孔３０５及び螺合部材受け止め孔２０８に徐々に進入する。螺合部材２０７が進入して、固定部３０２がパイプ２０１に接する状態に達し、そこから螺合部材２０７をさらに回転して締め込むことで、固定部３０２がパイプ２０１に固定される。なお、固定部開口孔３０５の位置や形状は、上記に限定されるものではない。なお、図３に示したパイプキャップ２０２の形状は一例であって、その他の形状であってもよい。 Further, the fixing portion 302 has a fixing portion opening hole 305 which is an opening hole into which a screwing member 207 for fixing the pipe cap 202 to the pipe 201 is inserted. The fixed portion opening hole 305 is provided, for example, in a substantially central portion of the fixed portion 302. The screwing member 207 is, for example, a screw, and is passed through the screwing member receiving hole 208 of the pipe 201 after the screwing member 207 is passed through the fixed portion opening hole 305 of the pipe cap 202. A female screw is formed in advance in the screwing member receiving hole 208, or a female screw shape is formed in the screwing member receiving hole 208 by the rotation of the screwing member 207, so that the screwing member 207 rotates (in the present embodiment). Then, the screwing member 207 gradually enters the fixing portion opening hole 305 and the screwing member receiving hole 208. The fixing member 302 is fixed to the pipe 201 by entering the screwing member 207 and reaching the state where the fixing portion 302 contacts the pipe 201, and further rotating and tightening the screwing member 207 from there. The position and shape of the fixed part opening hole 305 are not limited to the above. The shape of the pipe cap 202 shown in FIG. 3 is an example, and other shapes may be used.
　浮き防止部３０３は、螺合部材２０７の回転に伴う、蓋部３０１のパイプ２０１の開口端部２０６からの浮きを防止する。具体的には、例えば、図３、図４及び図５に示すように、浮き防止部３０３は、蓋部３０１の底面３０４から、図３の右側の上方に延伸して、図３の左側に湾曲した後に、下方に延伸するように一体的に形成される。具体的には、図３の上方に延伸する部分を脚部３０６と呼び、脚部３０６から左側に湾曲する部分を連結部３０７と呼び、連結部から下方に延伸する部分を手掌部３０８と呼ぶ。 The floating prevention unit 303 prevents the lid 301 from floating from the open end 206 of the pipe 201 due to the rotation of the screwing member 207. Specifically, for example, as shown in FIGS. 3, 4, and 5, the floating prevention portion 303 extends upward from the bottom surface 304 of the lid portion 301 to the right side of FIG. 3 and to the left side of FIG. After being curved, it is integrally formed so as to extend downward. Specifically, the portion extending upward in FIG. 3 is referred to as a leg portion 306, the portion curved leftward from the leg portion 306 is referred to as a connecting portion 307, and the portion extending downward from the connecting portion is referred to as a palm portion 308. .
　脚部３０６は、例えば、板状の形状を有する。また、脚部３０６は、図３に示すように、例えば、蓋部３０１の底面３０４に、略垂直に設ける。螺合部材２０７を時計方向５０１に回す場合には、脚部３０６の外側面は、例えば、パイプキャップ２０２をパイプ２０１に挿入したときに、図５においてパイプ２０１左側の内側の側面４０１に接するように設ける。具体的には、例えば、パイプキャップ２０２をパイプ２０１に取り付けた際に、脚部３０６の外側面が、パイプ２０１の開口端部２０６の内側の側面４０１と面接触するように形成され、また、後述する螺合部材による回転力に抗することのできる長さを有するように構成する。脚部３０６の長さは、蓋部３０１の底面３０４から固定部開口孔３０５までの長さより長いことが好ましい。後述するように蓋部３０１の底面３０４から固定部開口孔３０５までの長さより短い場合より、螺合部材２０７による回転力をより効果的に抑制することができる。 The leg portion 306 has, for example, a plate shape. Further, as shown in FIG. 3, the leg portion 306 is provided, for example, substantially vertically on the bottom surface 304 of the lid portion 301. When the screw member 207 is rotated clockwise 501, the outer surface of the leg portion 306 contacts the inner side surface 401 on the left side of the pipe 201 in FIG. 5 when the pipe cap 202 is inserted into the pipe 201, for example. To be installed. Specifically, for example, when the pipe cap 202 is attached to the pipe 201, the outer surface of the leg portion 306 is formed so as to make surface contact with the inner side surface 401 of the opening end portion 206 of the pipe 201. It is configured to have a length that can resist the rotational force of the screwing member described later. The length of the leg portion 306 is preferably longer than the length from the bottom surface 304 of the lid portion 301 to the fixed portion opening hole 305. As will be described later, the rotational force by the screw member 207 can be more effectively suppressed than in the case where the length is shorter than the length from the bottom surface 304 of the lid portion 301 to the fixed portion opening hole 305.
　連結部３０７は、脚部３０６に延伸して設けられる。連結部３０７は、例えば、脚部３０６と同じ幅を持つ円弧状の形状を有する。 The connecting portion 307 is provided by extending the leg portion 306. The connecting portion 307 has, for example, an arcuate shape having the same width as the leg portion 306.
　手掌部３０８は、連結部３０７に延伸して設けられる。手掌部３０８は、例えば連結部３０７と同じ幅を持つ板状の形状を有する。手掌部３０８は、図５に示すように、パイプ２０１の内側の側壁、例えば４０２に沿うように設けられる。 The palm part 308 is provided extending to the connecting part 307. The palm portion 308 has, for example, a plate shape having the same width as the connecting portion 307. As shown in FIG. 5, the palm portion 308 is provided along a side wall inside the pipe 201, for example, 402.
　脚部３０６の外側から手掌部３０８の先端外側までの長さ５０２は、パイプ２０１の内側の側面４０１から側面４０２までの長さと略同じか若干長く形成される。脚部３０６、連結部３０７、及び手掌部３０８は、例えば、図５に示すように、一体的に形成され、所定の幅を有したＪ型形状を有する。 A length 502 from the outside of the leg 306 to the outside of the tip of the palm 308 is formed to be substantially the same as or slightly longer than the length from the side surface 401 to the side surface 402 inside the pipe 201. For example, as shown in FIG. 5, the leg portion 306, the connecting portion 307, and the palm portion 308 are integrally formed and have a J-shape having a predetermined width.
　次に、図４を用いて、パイプキャップ２０２の、パイプ２０１への取り付け方法について説明する。まず、矢印４０３に示すように、パイプキャップ２０２の脚部３０６、連結部３０７、及び手掌部３０８（浮き防止部３０３）が、パイプ２０１の開口端部２０６に挿入される。このとき、パイプキャップ２０２の手掌部３０８の少なくとも先端部はパイプ２０１の内側の側面４０２に接し、連結部３０７は円弧形状が潰れる方向に若干弾性変形する。 Next, a method of attaching the pipe cap 202 to the pipe 201 will be described with reference to FIG. First, as shown by an arrow 403, the leg portion 306 of the pipe cap 202, the connecting portion 307, and the palm portion 308 (floating prevention portion 303) are inserted into the open end portion 206 of the pipe 201. At this time, at least the tip of the palm portion 308 of the pipe cap 202 is in contact with the inner side surface 402 of the pipe 201, and the connecting portion 307 is slightly elastically deformed in the direction in which the arc shape is crushed.
　次に、螺合部材２０７がパイプキャップ２０２の固定部開口孔３０５を介して、パイプ２０１の螺合部材受け止め孔２０８に取り付けられる。なお、螺合部材２０７は、ビスの他、ボルト及びナット等、その他の回転に基づく取り付け部材であればその他の取り付け部材であってもよい。この点については下記についても同様である。 Next, the screwing member 207 is attached to the screwing member receiving hole 208 of the pipe 201 through the fixing portion opening hole 305 of the pipe cap 202. The screwing member 207 may be a screw, a bolt, a nut, or any other attachment member based on rotation, as long as it is another attachment member. This also applies to the following.
　次に、図５を用いて、より具体的に、説明する。図５は、パイプ２０１にパイプキャップ２０２を取り付けたときの断面図である。図５は図４のＶ－Ｖ断面を示した断面図である。 Next, a more specific explanation will be given using FIG. FIG. 5 is a cross-sectional view when the pipe cap 202 is attached to the pipe 201. FIG. 5 is a cross-sectional view showing a VV cross section of FIG.
　上記のように、螺合部材２０７がパイプキャップ２０２の固定部開口孔３０５を介して、パイプ２０１の螺合部材受け止め孔２０８に取り付けられる。ここで、例えば、螺合部材２０７を５０１に示す方向に回転させて、パイプ２０１とパイプキャップ２０２がビス止めされる。このとき、螺合部材２０７を回転させる力により、パイプキャップ２０２には回転方向に応じた矢印５０１に示す方向の力が働く。これにより、図５のパイプ２０１の右側の開口端にはパイプキャップ２０２を当該右側の開口端に押し付ける力が働き、一方、パイプ２０１材の左側の開口端にはパイプキャップ２０２を当該左側の開口端から浮き上がる力が働くこととなる。 As described above, the screwing member 207 is attached to the screwing member receiving hole 208 of the pipe 201 via the fixing portion opening hole 305 of the pipe cap 202. Here, for example, the screw member 207 is rotated in the direction shown by 501 to screw the pipe 201 and the pipe cap 202. At this time, the force of rotating the screwing member 207 acts on the pipe cap 202 in the direction indicated by the arrow 501 according to the rotation direction. As a result, a force that presses the pipe cap 202 against the right open end of the pipe 201 in FIG. 5 acts, while the pipe cap 202 is attached to the left open end of the pipe 201 material. The force that lifts from the edge will work.
　しかしながら、本実施の形態によれば、パイプキャップ２０２の手掌部３０８の少なくとも先端部がパイプ２０１の内側の側面４０２に接し、連結部３０７は円弧形状が潰れる方向に若干弾性変形しているので、パイプキャップ２０２の脚部３０６の外側面は、パイプ２０１の開口端部２０６の内側の側面４０１に押し付けられた状態で面接触している。したがって、パイプキャップ２０２の脚部３０６の外側面とパイプ２０１の側面４０１との摩擦力が増加しているため、矢印５０１に示す方向の力によって、図５のパイプ２０１の左側の開口端からパイプキャップ２０２が浮き上がる力が働いても、この浮き上がる力に抗することができる。 However, according to this embodiment, at least the tip of the palm portion 308 of the pipe cap 202 is in contact with the inner side surface 402 of the pipe 201, and the connecting portion 307 is slightly elastically deformed in the direction in which the arc shape is crushed. The outer surface of the leg portion 306 of the pipe cap 202 is in surface contact with the inner side surface 401 of the opening end portion 206 of the pipe 201 in a pressed state. Therefore, since the frictional force between the outer side surface of the leg portion 306 of the pipe cap 202 and the side surface 401 of the pipe 201 is increased, the force in the direction indicated by the arrow 501 causes the pipe 201 to open from the left open end of the pipe 201 in FIG. Even if the cap 202 is lifted, the lift can be resisted.
　また、本実施の形態によれば、パイプキャップ２０２の右側は、手掌部３０８の一部がパイプ２０１の内側の側面４０２に接しているだけであり、手掌部３０８は蓋部３０１の底面３０４に連結していない。したがって、図５においてパイプ２０１の右側の開口端にパイプキャップ２０２を当該右側の開口端に押し付ける力が働いても、その力はパイプ２０１の内側の側面４０２にはほとんど作用しないので、パイプ２０１の内側の側面４０２に下方にかかる力の反作用によるパイプキャップ２０２の浮き上がりを抑制する。 Further, according to the present embodiment, on the right side of the pipe cap 202, only a part of the palm portion 308 is in contact with the inner side surface 402 of the pipe 201, and the palm portion 308 is provided on the bottom surface 304 of the lid portion 301. Not linked. Therefore, in FIG. 5, even if the force pressing the pipe cap 202 to the right open end of the pipe 201 acts on the right open end of the pipe 201, the force hardly acts on the inner side surface 402 of the pipe 201. The lifting of the pipe cap 202 due to the reaction of the downward force on the inner side surface 402 is suppressed.
　すなわち、本実施の形態では、螺合部材２０７がパイプキャップ２０２をパイプ２０１に固定すべく締め付ける回転方向に対して、パイプキャップ２０２がパイプ２０１から浮き上がる側のパイプキャップ２０２とパイプ２０１との接触面積を、パイプキャップ２０２がパイプ２０１に押し付けられる側のパイプキャップ２０２とパイプ２０１との接触面積よりも大きくしている。これにより、パイプキャップ２０２に回転方向に応じた矢印５０１に示す方向に力が働いたとしても、上記のような脚部３０６、連結部３０７、手掌部３０８（浮き防止部３０３）により、パイプ２０１の内側の側面４０１，４０２に対するパイプキャップ２０２の摩擦力が異なるようにしていることから、当該力によるパイプキャップ２０２の回転を抑制し、よって、パイプキャップ２０２のパイプ２０１への取り付け時にパイプキャップ２０２の一端がパイプ２０１の開口端端部から浮き上がることを抑制することができる。また、これにより、例えば、当該パイプ２０１が冷蔵庫１００等のハンドル１０２に取り付けられた場合に、パイプキャップ２０２がパイプ２０１の開口端から浮いた状態となる等の冷蔵庫１００等の外観上の支障を抑制することができる。 That is, in the present embodiment, the contact area between the pipe cap 202 and the pipe 201 on the side where the pipe cap 202 floats from the pipe 201 with respect to the rotation direction in which the screwing member 207 tightens to fix the pipe cap 202 to the pipe 201. Is larger than the contact area between the pipe cap 202 and the pipe 201 on the side where the pipe cap 202 is pressed against the pipe 201. Thus, even if a force acts on the pipe cap 202 in the direction indicated by the arrow 501 depending on the rotation direction, the leg 201, the connecting portion 307, and the palm portion 308 (floating preventing portion 303) as described above cause the pipe 201 to move. Since the frictional force of the pipe cap 202 with respect to the inner side surfaces 401 and 402 of the pipe cap 202 is different, rotation of the pipe cap 202 due to the force is suppressed, and therefore, when the pipe cap 202 is attached to the pipe 201, the pipe cap 202 is prevented. It is possible to prevent one end of the above from floating from the open end portion of the pipe 201. Further, this causes a hindrance to the appearance of the refrigerator 100 or the like, for example, when the pipe 201 is attached to the handle 102 of the refrigerator 100 or the like, the pipe cap 202 floats from the opening end of the pipe 201. Can be suppressed.
　なお、本発明は、上記実施の形態に限定されるものではなく、種々の変形が可能である。例えば、上記実施の形態で示した構成と実質的に同一の構成、同一の作用効果を奏する構成又は同一の目的を達成することができる構成で置き換えてもよい。例えば、手掌部３０８は、蓋部３０１をパイプ２０１に押し付ける力が直接加わらないような構造としていれば、蓋部３０１の近傍まで延伸したり、蓋部３０１に連結していてもよい。 Note that the present invention is not limited to the above embodiment, and various modifications can be made. For example, it may be replaced with a configuration that is substantially the same as the configuration described in the above-described embodiment, a configuration that exhibits the same operational effect, or a configuration that can achieve the same object. For example, the palm portion 308 may extend to the vicinity of the lid portion 301 or be connected to the lid portion 301 as long as the palm portion 308 has a structure in which the force pressing the lid portion 301 against the pipe 201 is not directly applied.
　さらに、本発明の一態様にかかるパイプキャップ２０２を、パイプ２０１形状のハンドル１０２に用いることができる。例えば、図２に示すように、例えばアルミニウムの引き抜き材の端部の開口部に本発明の一態様に係るパイプキャップ２０２を用いても良い。パイプ２０１とパイプキャップ２０２の間に隙間のないハンドル１０２が得られる。 Furthermore, the pipe cap 202 according to one embodiment of the present invention can be used for the handle 102 having the shape of the pipe 201. For example, as shown in FIG. 2, for example, the pipe cap 202 according to one embodiment of the present invention may be used in the opening of the end of the aluminum drawn material. The handle 102 having no gap between the pipe 201 and the pipe cap 202 is obtained.
　また、本発明の一態様に係るパイプキャップ２０２を図１に示すように冷蔵庫１００の扉１０１のハンドル１０２のパイプキャップ２０２に用いてもよい。ハンドル１０２とパイプキャップ２０２の間に隙間のない冷蔵庫１００が得られる。冷蔵庫１００は料理中、頻繁に冷蔵庫１００のハンドル１０２を汚れた手で握ることが多い。このため冷蔵庫１００のハンドル１０２は汚れることが多く、掃除を頻繁する必要がある。このような冷蔵庫１００に、ハンドル１０２とパイプキャップ２０２の間に隙間があると、汚れが隙間に入り込み、容易の掃除することができない。本発明の一態様にかかるパイプキャップ２０２を用いた場合、汚れがハンドル１０２とパイプキャップ２０２の間に隙間入り込むことを抑制し得る。 The pipe cap 202 according to one embodiment of the present invention may be used as the pipe cap 202 of the handle 102 of the door 101 of the refrigerator 100 as shown in FIG. The refrigerator 100 having no gap between the handle 102 and the pipe cap 202 can be obtained. The refrigerator 100 often holds the handle 102 of the refrigerator 100 with dirty hands during cooking. For this reason, the handle 102 of the refrigerator 100 is often dirty and needs to be cleaned frequently. If there is a gap between the handle 102 and the pipe cap 202 in such a refrigerator 100, dirt enters the gap and cannot be easily cleaned. When the pipe cap 202 according to one embodiment of the present invention is used, dirt can be prevented from entering a gap between the handle 102 and the pipe cap 202.

　ガイド部６０２は、本体部６１２と第２部材６１３を有する。 The guide part 602 has a main body part 612 and a second member 613.
　本体部６１２は、図７に示すように、パイプ２０１に挿入可能な大きさの、例えば、長方体形状を有する。本体部６１２には螺合部材２０７を挿入するための挿入孔６１４を有する。挿入孔６１４は例えば、長方体の一面の中央部に設けられる。 As shown in FIG. 7, the main body portion 612 has a size such that it can be inserted into the pipe 201, for example, a rectangular shape. The main body portion 612 has an insertion hole 614 for inserting the screwing member 207. The insertion hole 614 is provided, for example, in the center of one surface of the rectangular parallelepiped.
　第２部材６１３は、図６（ｄ）に示すように、本体部６１２の、例えば、上面６１５に図６（ｄ）上方に向かって第２脚部６１６を有する。第２脚部６１６の上端には、図６（ｄ）左側に延伸する第２突起部６１７を有する。第２突起部６１７の先端には、図６（ｄ）下方に突起する第２引っ掛け部６１８を有する。第２脚部６１６、第２突起部６１７、第２引っ掛け部６１８の幅は、蓋部６０１の開口部６１１の幅より狭い。図６（ｂ）に示すように、蓋部６０１の開口部６１１にガイド部６０２の第２部材６１３が挿入される。第１引っ掛け部６０９と第２引っ掛け部６１８が、互いにかみ合い、蓋部６０１にガイド部６０２が引っ掛けられる。 As shown in FIG. 6D, the second member 613 has a second leg 616 on the upper surface 615 of the main body 612, for example, toward the upper side in FIG. 6D.

　パイプ２０１の構成は、図７に示すように、第１の実施形態と同様である。ただし、螺合部材受け止め孔２０８は、螺合部材が貫通する螺合部材貫通孔７０１に変更されている。また、螺合部材貫通孔７０１の位置は、螺合部材２０７がガイド部６０２の挿入孔６１４を介して本体部６１２に締め込まれ、ガイド部６０２がパイプ２０１に固定されたときに、ガイド部６０２が蓋部６０１をパイプ２０１に引き込み、パイプ２０１開口端部２０６と底面６０５の間に隙間が生じないように構成される。 The structure of the pipe 201 is the same as that of the first embodiment, as shown in FIG. However, the screw member receiving hole 208 is changed to a screw member through hole 701 through which the screw member penetrates. Further, the position of the screwing member through hole 701 is such that when the screwing member 207 is fastened to the main body portion 612 through the insertion hole 614 of the guide portion 602 and the guide portion 602 is fixed to the pipe 201. A lid 602 draws the lid 601 into the pipe 201 so that no gap is created between the open end 206 of the pipe 201 and the bottom surface 605.
　図７は、本実施形態にかかるパイプキャップ２０２をパイプ２０１と取り付ける方法を示す概略図である。図８は本実施形態にかかるパイプキャップ２０２の機能を説明する図７のＶＩＩＩ－ＶＩＩＩ断面の断面図である。図７及び図８を用いて、本実施形態におけるパイプキャップ２０２のパイプ２０１への取り付けについて説明する。 FIG. 7 is a schematic diagram showing a method of attaching the pipe cap 202 to the pipe 201 according to the present embodiment. FIG. 8 is a cross-sectional view of the VIII-VIII cross section of FIG. 7 for explaining the function of the pipe cap 202 according to the present embodiment. The attachment of the pipe cap 202 to the pipe 201 in this embodiment will be described with reference to FIGS. 7 and 8.
　まず、図８（ａ）の矢印８０１に示すように、蓋部６０１の開口部６１１に、ガイド部６０２の第２部材６１３が挿入される。次に、図８（ｂ）に示すように、蓋部６０１の第１引っ掛け部６０９にガイド部６０２の第２引っ掛け部６１８を引っ掛けたパイプキャップ２０２がパイプ２０１の開口端部２０６に挿入される。次に、図８（ｃ）に示すように、螺合部材２０７がパイプ２０１の螺合部材貫通孔７０１を介して、ガイド部６０２の挿入孔６１４に、挿入される。そして、図８（ｄ）に示すように、螺合部材２０７がガイド部６０２の挿入孔６１４にねじ込まれるに伴い、螺合部材２０７の回転に基づいて、螺合部材２０７は図８（ｄ）右側に進む。 First, as shown by an arrow 801 in FIG. 8A, the second member 613 of the guide 602 is inserted into the opening 611 of the lid 601. Next, as shown in FIG. 8B, the pipe cap 202 in which the first hook portion 609 of the lid portion 601 is hooked with the second hook portion 618 of the guide portion 602 is inserted into the open end portion 206 of the pipe 201. . Next, as shown in FIG. 8C, the screwing member 207 is inserted into the insertion hole 614 of the guide portion 602 through the screwing member through hole 701 of the pipe 201. Then, as shown in FIG. 8D, as the screwing member 207 is screwed into the insertion hole 614 of the guide portion 602, the screwing member 207 rotates as shown in FIG. Go to the right.
　螺合部材２０７が図８（ｄ）右側に進むと、矢印８０２で示すように、ガイド部６０２は図８（ｄ）左側に移動し、最終的にパイプキャップ２０２がパイプ２０１に固定される。ガイド部６０２が図８（ｄ）左側に移動すると、パイプ２０１の開口端部２０６に挿入された第２部材６１３も図８（ｄ）左側に移動する。第２部材６１３が図８（ｄ）左側に移動すると、第２引っ掛け部６１８は第１突起部６０７の傾斜部６０８に接しながら、図８（ｄ）左側に移動する。第２引っ掛け部６１８が第１突起部６０７の傾斜部６０８に接しながら図８（ｄ）の左側に移動すると、第２引っ掛け部６１８は蓋部６０１を矢印８０３方向のパイプ２０１の開口端部２０６側に引き込む。これにより、パイプキャップ２０２の浮きが防止される。 When the threaded member 207 moves to the right side in FIG. 8D, the guide portion 602 moves to the left side in FIG. 8D as indicated by an arrow 802, and finally the pipe cap 202 is fixed to the pipe 201. When the guide portion 602 moves to the left side in FIG. 8D, the second member 613 inserted in the open end portion 206 of the pipe 201 also moves to the left side in FIG. 8D. When the second member 613 moves to the left side in FIG. 8D, the second hooking portion 618 moves to the left side in FIG. 8D while contacting the inclined portion 608 of the first protrusion 607. When the second hooking portion 618 moves to the left side in FIG. 8D while contacting the inclined portion 608 of the first protrusion 607, the second hooking portion 618 causes the lid 601 to move the lid 601 toward the opening end 206 of the pipe 201 in the direction of arrow 803. Pull to the side. This prevents the pipe cap 202 from floating.
＜第３の実施形態＞

　パイプ２０１の構成は、図９に示すように、第２の実施形態と同様である。螺合部材貫通孔７０１の位置は、螺合部材２０７がガイド部９０２の本体部６１２の挿入孔６１４に締め込まれ、ガイド部９０２がパイプ２０１に固定されたときに、ガイド部９０２が蓋部９０１をパイプ２０１に引き込み、パイプ２０１の開口端部２０６と蓋部９０１の底部との間に隙間が生じないように構成される。 The structure of the pipe 201 is the same as that of the second embodiment, as shown in FIG. The position of the threaded member through hole 701 is such that when the threaded member 207 is screwed into the insertion hole 614 of the main body portion 612 of the guide portion 902 and the guide portion 902 is fixed to the pipe 201, the guide portion 902 is closed. 901 is drawn into the pipe 201 so that there is no gap between the open end 206 of the pipe 201 and the bottom of the lid 901.
　まず、図１１（ａ）に示すように、蓋部９０１における枠部９０３の開口部に、ガイド部９０２の第４部材９０４を挿入し、さらに、枠部９０３の穴部１１５に第３突起部９０６をはめ込む。次に、図１１（ｂ）に示すように、蓋部９０１の穴部１１５に第３突起部９０６をはめ込んだパイプキャップ２０２がパイプ２０１に挿入される。そして、図１１（ｃ）に示すように、螺合部材２０７がパイプ２０１の螺合部材貫通孔７０１を介して、ガイド部９０２における本体部６１２の挿入孔６１４に、挿入される。さらに、螺合部材２０７が挿入孔６１４にねじ込まれるに伴い、螺合部材２０７の回転に基づいて、螺合部材２０７は図１１（ｄ）の右側に進む。さらに、螺合部材２０７が図１１（ｄ）の右側に進むに従い、ガイド部９０２は矢印１１８で示すように左側に移動し、最終的にパイプ２０１の内側の側壁に固定される。ガイド部が矢印１１８方向に移動すると、ガイド部９０２の第３突起部９０６も、穴部１１５の傾斜部１１６をスライドしながら図１１（ｄ）の左側に移動する。第３突起部９０６が傾斜部１１６をスライドすると、第３突起部９０６は、傾斜部１１６の傾斜に従い蓋部９０１を矢印１１９方向に引き込む。これにより、パイプキャップ２０２の浮きが防止される。 First, as shown in FIG. 11A, the fourth member 904 of the guide portion 902 is inserted into the opening portion of the frame portion 903 in the lid portion 901, and the third protrusion portion is further inserted into the hole 115 of the frame portion 903. Insert 906. Next, as shown in FIG. 11B, the pipe cap 202 in which the third protrusion 906 is fitted in the hole 115 of the lid 901 is inserted into the pipe 201. Then, as shown in FIG. 11C, the screwing member 207 is inserted into the insertion hole 614 of the main body portion 612 of the guide portion 902 through the screwing member through hole 701 of the pipe 201. Further, as the screwing member 207 is screwed into the insertion hole 614, the screwing member 207 moves to the right side in FIG. 11D based on the rotation of the screwing member 207. Further, as the screwing member 207 moves to the right side in FIG. 11D, the guide portion 902 moves to the left side as shown by the arrow 118, and finally is fixed to the inner side wall of the pipe 201. When the guide portion moves in the direction of arrow 118, the third protruding portion 906 of the guide portion 902 also moves to the left side in FIG. 11D while sliding the inclined portion 116 of the hole 115. When the third protruding portion 906 slides on the inclined portion 116, the third protruding portion 906 draws the lid portion 901 in the arrow 119 direction according to the inclination of the inclined portion 116. This prevents the pipe cap 202 from floating.
＜第４の実施形態＞
　次に、本発明の第４の実施形態について説明する。第４の実施形態では、パイプキャップ２０２及びパイプ２０１の構成が上記第１の実施形態と異なる。その他の点は、上記第1の実施形態と同様であり、同様である点については説明を省略する。 <Fourth Embodiment>
Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, the configurations of the pipe cap 202 and the pipe 201 are different from those in the first embodiment. The other points are the same as those of the first embodiment, and the description of the same points will be omitted.
　図１２は、パイプキャップ２０２の概要を示す斜視図である。図１２に示すように、パイプキャップ２０２は、蓋部３０１と固定部３０２とを有する。蓋部３０１は、第１の実施形態と同様の形状を有する。 FIG. 12 is a perspective view showing an outline of the pipe cap 202. As shown in FIG. 12, the pipe cap 202 has a lid portion 301 and a fixing portion 302. The lid portion 301 has the same shape as that of the first embodiment.
　固定部３０２は、第１の実施形態の固定部と同様の形状であるが、さらに、第４突起部１２１を有する。第４突起部１２１は、後述するパイプ２０１の穴部１３１に挿入されるとともに、固定部３０２の面から先端に向かって直径が小さくなる形状を有する。つまり、第４突起部１２１は、先端から固定部に向かって傾斜を有する。第４突起部１２１は、パイプキャップ２０２がパイプ２０１に挿入されたとき、パイプ２０１の穴部１３１に対向する位置に設けられる。 The fixing part 302 has the same shape as the fixing part of the first embodiment, but further has a fourth protrusion 121. The fourth protrusion 121 is inserted into a hole 131 of the pipe 201, which will be described later, and has a shape in which the diameter decreases from the surface of the fixed portion 302 toward the tip. That is, the fourth protrusion 121 has an inclination from the tip toward the fixed portion. The fourth protrusion 121 is provided at a position facing the hole 131 of the pipe 201 when the pipe cap 202 is inserted into the pipe 201.
　パイプ２０１の構成は、第１の実施形態のパイプ２０１の構成と同様の構成であるが、図１３に示すように、さらに、第４突起部１２１が挿入される穴部１３１が設けられる。 The structure of the pipe 201 is similar to that of the pipe 201 of the first embodiment, but as shown in FIG. 13, a hole 131 into which the fourth protrusion 121 is inserted is further provided.
　穴部１３１の位置は、パイプキャップ２０２をパイプ２０１に挿入したとき、第４突起部１２１が対向する位置に設ける。より具体的には、図１４（ｂ）に示すように、蓋部３０１の底面３０４から第４突起部１２１の先端までの長さ１４２、蓋部の底面３０４から第４突起部１２１の根元までの長さ１４１、パイプ２０１の開口端部２０６から穴部１３１の上端までの長さ１４３とすると、長さ１４３は長さ１４１に略等しく、長さ１４２より短い関係を有する。 The hole 131 is provided at a position where the fourth protrusion 121 faces when the pipe cap 202 is inserted into the pipe 201. More specifically, as shown in FIG. 14B, the length 142 from the bottom surface 304 of the lid 301 to the tip of the fourth protrusion 121, the bottom 304 of the lid to the base of the fourth protrusion 121. 141, and the length 143 from the open end 206 of the pipe 201 to the upper end of the hole 131, the length 143 is substantially equal to the length 141 and shorter than the length 142.
　図１３は、本実施形態におけるパイプキャップ２０２をパイプ２０１に取り付ける方法を示す概略図である、図１４は、パイプ２０１にパイプキャップ２０２を取り付けた後、図１３のＸＩＶ－ＸＩＶ断面の断面図であり、本実施形態にかかるパイプキャップ２０２の機能を説明するための断面図である。図１４（ａ）は、螺合部材２０７をねじ込み、第４突起部１２１が、パイプ２０１に接したときの断面を示す。図１４（ｂ）は図１４（ａ）の拡大を示す。図１４（ｃ）は、螺合部材２０７をねじ込み、固定部３０２をパイプ２０１の外側の側面に固定したときの断面を示す。図１３及び図１４を用いて、パイプキャップ２０２をパイプ２０１への取り付ける方法及び、機能について説明する。 FIG. 13 is a schematic view showing a method for attaching the pipe cap 202 to the pipe 201 in the present embodiment. FIG. 14 is a cross-sectional view taken along the line XIV-XIV of FIG. 13 after attaching the pipe cap 202 to the pipe 201. There is a sectional view for explaining the function of the pipe cap 202 according to the present embodiment. FIG. 14A shows a cross section when the screw member 207 is screwed in and the fourth protrusion 121 is in contact with the pipe 201. FIG. 14 (b) shows an enlargement of FIG. 14 (a). FIG. 14C shows a cross section when the screwing member 207 is screwed in and the fixing portion 302 is fixed to the outer side surface of the pipe 201. A method and function of attaching the pipe cap 202 to the pipe 201 will be described with reference to FIGS. 13 and 14.
　まず、パイプキャップ２０２は、図１４に示すように、固定部３０２が、パイプ２０１の外側の側面に沿うようにパイプ２０１に挿入される。次に螺合部材２０７を固定部３０２の固定部開口孔３０５を貫通させ、パイプ２０１の螺合部材受け止め孔２０８に挿入する。そして、螺合部材２０７をねじ込み、固定部３０２をパイプ２０１外側の側面に固定することによりパイプキャップ２０２を固定する。 First, in the pipe cap 202, as shown in FIG. 14, the fixing portion 302 is inserted into the pipe 201 so as to extend along the outer side surface of the pipe 201. Next, the screwing member 207 is inserted into the screwing member receiving hole 208 of the pipe 201 by penetrating the fixing portion opening hole 305 of the fixing portion 302. Then, the pipe cap 202 is fixed by screwing the screwing member 207 and fixing the fixing portion 302 to the outer side surface of the pipe 201.
　次に、図１４を用いて、より具体的に、説明する。パイプ２０１の開口端部２０６から穴部１３１の上端までの長さ１４３よりも、蓋部３０１の底面３０４から第４突起部１２１の先端までの長さ１４２の方が長い関係から、パイプキャップ２０２をパイプ２０１に挿入したときに蓋部３０１の底面３０４がパイプ２０１の開口端部２０６から若干浮いている状態であったとしても、第４突起部１２１の先端がパイプ２０１の穴部１３１の上端よりも下方に位置することができる。したがって、図１４（ｂ）に示すように、まず、螺合部材２０７をねじ込み始めると、第４突起部１２１の先端は、図１４（ｂ）のパイプ２０１の穴部１３１に進入する。さらに、螺合部材２０７をねじ込まれると、第４突起部１２１の傾斜がパイプ２０１の穴部１３１の上端をスライドし、固定部３０２はパイプ２０１の下方に向かって移動する。そして、螺合部材２０７が、固定部３０２とパイプ２０１の外側の側面と接するまで進むと、図１４（ｃ）に示すように、長さ１４３を長さ１４１とを略等しくしているため、固定部３０２が設けられた蓋部３０１の底面３０４がパイプ２０１の開口端部２０６に接し、パイプキャップ２０２とパイプ２０１との間に隙間が形成されることが防止される。 Next, a more specific description will be given with reference to FIG. Since the length 142 from the bottom surface 304 of the lid 301 to the tip of the fourth protrusion 121 is longer than the length 143 from the open end 206 of the pipe 201 to the upper end of the hole 131, the pipe cap 202 Even if the bottom surface 304 of the lid portion 301 is slightly floating from the open end portion 206 of the pipe 201 when is inserted into the pipe 201, the tip of the fourth protrusion 121 is the upper end of the hole 131 of the pipe 201. Can be located below. Therefore, as shown in FIG. 14B, first, when the screwing member 207 starts to be screwed, the tip of the fourth protrusion 121 enters the hole 131 of the pipe 201 of FIG. 14B. Further, when the screwing member 207 is screwed in, the inclination of the fourth protrusion 121 slides on the upper end of the hole 131 of the pipe 201, and the fixing portion 302 moves downward of the pipe 201. Then, when the screwing member 207 advances until it comes into contact with the fixing portion 302 and the outer side surface of the pipe 201, the length 143 is made substantially equal to the length 141 as shown in FIG. The bottom surface 304 of the lid portion 301 provided with the fixing portion 302 is in contact with the open end portion 206 of the pipe 201 to prevent a gap from being formed between the pipe cap 202 and the pipe 201.
　本実施形態において、第４突起部１２１や穴部１３１の位置は、左右方向においては、螺合部材２０７が締まる回転方向に対して、パイプキャップ２０２が浮き上がる方向となる側（螺合部材２０７が時計回りで締まる方向の場合は、図１２や図１３に示すように螺合部材２０７の左側）に位置している。これにより、螺合部材２０７の締め付けにより固定部３０２が共回りして、パイプキャップ２０２を浮き上がらせる力が働いても、上述の通り、第４突起部１２１の傾斜がパイプ２０１の穴部１３１の上端をスライドし、固定部３０２をパイプ２０１の下方に向かって移動させるため、パイプキャップ２０２を浮き上がらせる力に抗することができる。また、第４突起部１２１や穴部１３１の位置は、上下方向においては、パイプ２０１の開口端部２０６と螺合部材受け止め孔２０８との間に位置している。これにより、上述の長さ１４１～１４３を全体的に短くできるため、精度が向上し、パイプキャップ２０２とパイプ２０１との間に隙間が形成されることがより確実に防止される。 In the present embodiment, the positions of the fourth protrusion 121 and the hole 131 are such that, in the left-right direction, the side in which the pipe cap 202 rises with respect to the rotation direction in which the screwing member 207 is tightened (the screwing member 207 is In the case of the clockwise tightening direction, it is located on the left side of the screw member 207 as shown in FIGS. 12 and 13. As a result, even if the fixing portion 302 rotates together with the fastening of the screwing member 207 and the force that lifts the pipe cap 202 acts, as described above, the inclination of the fourth projection 121 is the hole 131 of the pipe 201. Since the upper end is slid to move the fixed portion 302 toward the lower side of the pipe 201, it is possible to resist the force of floating the pipe cap 202. Further, the positions of the fourth protrusion 121 and the hole 131 are located between the opening end 206 of the pipe 201 and the screw member receiving hole 208 in the vertical direction. As a result, the lengths 141 to 143 described above can be shortened as a whole, so that the accuracy is improved and a gap is more reliably prevented from being formed between the pipe cap 202 and the pipe 201.
　なお、説明では、突起部をパイプキャップ２０２の固定部に、穴をパイプ２０１に設けた例で説明したが、逆に、突起部をパイプ２０１に、穴をパイプキャップ２０２の固定部に設けてもよい。また、突起部、穴は複数設けても良い。 In the description, the projection is provided on the fixing portion of the pipe cap 202 and the hole is provided on the pipe 201. However, conversely, the projection is provided on the pipe 201 and the hole is provided on the fixing portion of the pipe cap 202. Good. Also, a plurality of protrusions and holes may be provided.
＜第５の実施形態＞
　次に、本発明の第５の実施形態について説明する。第５の実施形態では、パイプキャップ１５０の構成が上記第１の実施形態と異なる。その他の点は、第１の実施形態と同様であり、同様である点については説明を省略する。 <Fifth Embodiment>
Next, a fifth embodiment of the present invention will be described. In the fifth embodiment, the structure of the pipe cap 150 is different from that of the first embodiment. The other points are the same as those of the first embodiment, and the description of the same points will be omitted.
　図１５は、パイプキャップ１５０の概要を示す斜視図である。図１５に示すように、パイプキャップ１５０は、蓋部３０１、固定部３０２、及び浮き防止部３０３を有する。蓋部３０１は、第１の実施形態と同様の形状を有する。固定部３０２は、第１の実施形態の固定部と同様の形態を有する。 FIG. 15 is a perspective view showing an outline of the pipe cap 150. As shown in FIG. 15, the pipe cap 150 has a lid portion 301, a fixing portion 302, and a floating prevention portion 303. The lid portion 301 has the same shape as that of the first embodiment. The fixing portion 302 has the same form as the fixing portion of the first embodiment.
　浮き防止部３０３は、図１５、図１６及び図１７に示すように、蓋部３０１の底面３０４から、図１５のｙ方向に延伸して、図１５の右側に屈曲し、右上方に延伸するように一体的に形成される。図１５のｙ方向に延伸する部分を第１脚部１５１と呼び、脚部から右に屈曲し延伸する部分を第２脚部１５２と呼ぶ。 As shown in FIGS. 15, 16 and 17, the floating prevention portion 303 extends from the bottom surface 304 of the lid portion 301 in the y direction of FIG. 15, bends to the right side of FIG. 15, and extends to the upper right side. Are integrally formed. The portion extending in the y direction in FIG. 15 is called the first leg portion 151, and the portion that bends and extends to the right from the leg portion is called the second leg portion 152.
　第１脚部１５１は、例えば、板状の形状を有する。また、第１脚部１５１は、図１６に示すように、パイプキャップ１５０をパイプ２０１に挿入したとき、第１脚部１５１がパイプ２０１の内側に挿入される位置に、蓋部３０１の底面３０４に略垂直に設ける。 The first leg 151 has, for example, a plate shape. In addition, as shown in FIG. 16, the first leg portion 151 has a bottom surface 304 of the lid portion 301 at a position where the first leg portion 151 is inserted inside the pipe 201 when the pipe cap 150 is inserted into the pipe 201. To be installed almost vertically.
　第２脚部１５２は、第１脚部１５１の先端に設け、図１７に示すように、例えば板状であり、第１脚部１５１と同じ幅を有する。第２脚部１５２は、螺合部材２０７を図１７において時計方向１７１に回す場合には、パイプ２０１の側面１７２に接して押圧するように設ける。第２脚部１５２の長さは、パイプの側面１７２に接する長さを備える。第１脚部１５１と第２脚部１５２が成す角度αは鈍角を有する。 The second leg portion 152 is provided at the tip of the first leg portion 151, has a plate shape, for example, and has the same width as the first leg portion 151, as shown in FIG. The second leg portion 152 is provided so as to come into contact with and press the side surface 172 of the pipe 201 when the screw member 207 is rotated clockwise 171 in FIG. The length of the second leg portion 152 is such that it contacts the side surface 172 of the pipe. The angle α formed by the first leg 151 and the second leg 152 has an obtuse angle.
　図１７は、図１６において、パイプ２０１にパイプキャップ１５０を取り付けた後のＸＶＩＩ－ＸＶＩＩ断面の断面図である。図１６及び図１７を用いて、パイプキャップ１５０をパイプ２０１への取り付ける方法について説明する。図１６に示すように、まず、パイプキャップ１５０を開口端部２０６に挿入する。固定部３０２をパイプ２０１の外側の側面に沿うようにパイプキャップ１５０をパイプ２０１に挿入する。次に螺合部材２０７を固定部３０２の固定部開口孔３０５を貫通させ、パイプ２０１の回転部材受け止め孔２０８に挿入する。さらに、螺合部材２０７をねじ込み、固定部３０２をパイプ２０１の外側の側面に固定する。 FIG. 17 is a cross-sectional view of the XVII-XVII cross section after the pipe cap 150 is attached to the pipe 201 in FIG. A method for attaching the pipe cap 150 to the pipe 201 will be described with reference to FIGS. 16 and 17. As shown in FIG. 16, first, the pipe cap 150 is inserted into the open end portion 206. The pipe cap 150 is inserted into the pipe 201 so that the fixing portion 302 extends along the outer side surface of the pipe 201. Next, the threaded member 207 is inserted into the rotary member receiving hole 208 of the pipe 201 by penetrating the fixed portion opening hole 305 of the fixed portion 302. Further, the screwing member 207 is screwed in to fix the fixing portion 302 to the outer side surface of the pipe 201.
　次に、図１７を用いて、より具体的に、説明する。図１７（ａ）に示すように、第１脚部１５１及び第２脚部１５２がパイプに挿入される。次に、螺合部材２０７が固定部３０２の固定部開口孔３０５を貫通し、回転部材受け止め孔２０８に挿入される。そして、図１７（ｂ）に示すように、螺合部材２０７が、例えば、矢印１７１の方向にねじ込まれると、第１の実施形態で説明したように、螺合部材２０７の回転する力が固定部３０２に伝わり、螺合部材２０７は、パイプキャップ１５０を、矢印１７１方向に回転させようとする。パイプキャップ１５０が１７１方向に回転しようとすると、第２脚部１５２はパイプ２０１内側の図１７の左側の側面１７２を矢印１７３の方向に押し、側面１７２と第２脚部１５２の間に生ずる摩擦力が増加して第２脚部１５２の先端を側面１７２に固定する。これにより、パイプキャップの浮きが防止される。 Next, a more specific description will be given with reference to FIG. As shown in FIG. 17A, the first leg 151 and the second leg 152 are inserted into the pipe. Next, the screw member 207 penetrates the fixed portion opening hole 305 of the fixed portion 302 and is inserted into the rotary member receiving hole 208. Then, as shown in FIG. 17B, when the screwing member 207 is screwed in, for example, the direction of the arrow 171, the rotating force of the screwing member 207 is fixed as described in the first embodiment. Transmitted to the portion 302, the screwing member 207 tries to rotate the pipe cap 150 in the arrow 171 direction. When the pipe cap 150 tries to rotate in the 171 direction, the second leg portion 152 pushes the side surface 172 on the left side in FIG. 17 inside the pipe 201 in the direction of arrow 173, and the friction generated between the side surface 172 and the second leg portion 152. The force is increased to fix the tip of the second leg portion 152 to the side surface 172. This prevents the pipe cap from floating.
　なお、第１脚部１５１及び第２脚部１５２が弾性変形可能な材料である場合には、パイプキャップ１５０を回転させようとする力は、図１７（ｃ）に示すように、第１脚部１５１及び第２脚部１５２を歪ませ、矢印１７４で示す方向に変形させる。次に、螺合部材２０７のねじ込みが終わり、螺合部材２０７をねじ込むドライバ（図示せず）が外されると、パイプキャップ１５０を矢印１７１方向に回転させようとする力は消失する。 When the first leg portion 151 and the second leg portion 152 are elastically deformable materials, the force for rotating the pipe cap 150 is the first leg as shown in FIG. 17C. The portion 151 and the second leg portion 152 are distorted and deformed in the direction indicated by the arrow 174. Next, when the screwing of the screwing member 207 is finished and the driver (not shown) for screwing the screwing member 207 is removed, the force for rotating the pipe cap 150 in the direction of the arrow 171 disappears.
　すると、図１７（ｃ）で説明した第１脚部１５１及び第２脚部１５２に生じた歪による変形は元に戻ろうとして、図１７（ｄ）に示すように、矢印１７４とは逆に１７５方向に変形する力が第２脚部１５２に生じる。第２脚部１５２に生じた１７５方向の力は、第２脚部１５２の先端とパイプ２０１内側の側面１７２との接触点が支点となって、第１脚部１５１を含むパイプキャップ１５０を矢印１７６方向に引き込み、パイプキャップ１５０がパイプ２０１の外に向かう力をさらに抑止し得る。これにより、パイプキャップの浮きが防止される。 Then, the deformation due to the strain generated in the first leg portion 151 and the second leg portion 152 described with reference to FIG. 17C is about to be restored, and as shown in FIG. A force that deforms in the 175 direction is generated in the second leg portion 152. The force in the 175 direction generated in the second leg portion 152 serves as a fulcrum at the contact point between the tip of the second leg portion 152 and the side surface 172 inside the pipe 201, and the force is applied to the pipe cap 150 including the first leg portion 151 by an arrow. 176, and the pipe cap 150 may further restrain the outward force of the pipe 201. This prevents the pipe cap from floating.
　なお、パイプキャップ１５０に固定部３０２を設ける例で説明したが、これに限定されるものではない。例えば、固定部３０２を設けず、第１脚部１５１に、螺合部材２０７を受ける孔を設けてもよい。 The example in which the fixing portion 302 is provided on the pipe cap 150 has been described, but the invention is not limited to this. For example, the fixing portion 302 may not be provided, and the first leg 151 may be provided with a hole for receiving the screwing member 207.
　本発明は、種々の変形が可能である。例えば、上述の構成と実質的に同一の構成、同一の作用効果を奏する構成又は同一の目的を達成することができる構成で置き換えることができる。 The present invention can be modified in various ways. For example, it can be replaced with a configuration that is substantially the same as the above-described configuration, a configuration that exhibits the same operational effect, or a configuration that can achieve the same object.
