It has.

貫通孔１２，１２は、本体部１１を隔壁２に取り付ける際の取り付け方向（図２において上下方向）に直交する方向、ここでは車幅方向に並んで形成され、それぞれ第一、第二ハーネスＨ１，Ｈ２の外径よりもわずかに小さい内径を有している。これにより、各貫通孔１２は、第一、第二ハーネスＨ１，Ｈ２を貫通させると共に軸方向へ移動しないように保持することができる。 The through holes 12, 12 are formed side by side in the direction perpendicular to the mounting direction (vertical direction in FIG. 2) when the main body 11 is mounted to the partition wall 2, here in the vehicle width direction. , H2 has an inner diameter slightly smaller than the outer diameter. Thereby, each through-hole 12 can be hold | maintained not to move to an axial direction while penetrating 1st, 2nd harness H1, H2.

係合溝部１３は、本体部１１の外周面１１ａからへこむように形成され、この外周面１１ａの周方向に延びている。なお、この係合溝部１３は、ここでは本体部１１の外周面１１ａのうち、上面１１ｂを除く両側面及び下面に形成されている。そして、この係合溝部１３には、隔壁２の上端部２ａに形成された凹所３が嵌入されるようになっている。 The engaging groove portion 13 is formed so as to be recessed from the outer peripheral surface 11a of the main body portion 11, and extends in the circumferential direction of the outer peripheral surface 11a. Here, the engaging groove portion 13 is formed on both side surfaces and the lower surface of the outer peripheral surface 11a of the main body portion 11 except for the upper surface 11b. Then, the recess 3 formed in the upper end 2 a of the partition wall 2 is fitted into the engagement groove 13.

また、この係合溝部１３のうち、図４に示すように、一対のスリット１５，１５の間に位置する部分（以下スリット間溝部という）１３Ａの幅Ｗ１が、一対のスリット１５，１５の間に位置しない部分（以下他の溝部という）１３Ｂの幅Ｗ２よりも広く形成されている。 In addition, as shown in FIG. 4, a width W 1 of a portion 13 A (hereinafter referred to as an inter-slit groove portion) 13 A of the engagement groove portion 13 is between the pair of slits 15, 15. It is formed wider than the width W2 of a portion (hereinafter referred to as other groove portion) 13B that is not located at the position.

なお、この幅Ｗ１及び幅Ｗ２は、隔壁２の厚み方向の幅であり、ここでは、他の溝部１３Ｂの幅Ｗ２は隔壁２の凹所３の厚みＴとほぼ同じ大きさに形成されているので、スリット間溝部１３Ａの幅Ｗ１は凹所３の厚みＴ（図２参照）よりも大きく形成されることとなる。 The width W1 and the width W2 are widths in the thickness direction of the partition wall 2. Here, the width W2 of the other groove 13B is formed to be approximately the same as the thickness T of the recess 3 of the partition wall 2. Therefore, the width W1 of the inter-slit groove portion 13A is formed larger than the thickness T of the recess 3 (see FIG. 2).

さらに、このスリット間溝部１３Ａの内側には、図５（ｂ）に示すように、本体部１１の外周面１１ａからへこむに連れて次第に突出する傾斜面１３ｃが形成されている。なお、この傾斜面１３ｃは、他の溝部１３Ｂには形成されていない（図５（ａ）参照）。 Further, as shown in FIG. 5B, an inclined surface 13 c that gradually protrudes as it is recessed from the outer peripheral surface 11 a of the main body portion 11 is formed inside the inter-slit groove portion 13 A. In addition, this inclined surface 13c is not formed in the other groove part 13B (refer Fig.5 (a)).

係合リブ部１４は、ここでは本体部１１の上面１１ｂに形成され（図３参照）、本体部１１の外周面１１ａよりも突出している。そして、この係合リブ部１４は、隔壁２の上端部２ａに沿って配置されるウェザーストリップ４の保持凹部５内に嵌入されるようになっている。 Here, the engagement rib portion 14 is formed on the upper surface 11 b of the main body portion 11 (see FIG. 3), and protrudes from the outer peripheral surface 11 a of the main body portion 11. The engaging rib portion 14 is inserted into the holding recess 5 of the weather strip 4 disposed along the upper end portion 2 a of the partition wall 2.

一対のスリット１５，１５は、本体部１１を隔壁２に取り付ける際の取付方向に沿って延在されると共に、それぞれ係合溝部１３を横切る位置に形成されており、ここでは、本体部１１の下側に形成されている。そして、各スリット１５により、本体部１１には一対の切れ目１５ａ，１５ａが形成されている。 The pair of slits 15 and 15 extend along the attachment direction when the main body 11 is attached to the partition wall 2 and are formed at positions crossing the engagement groove 13. It is formed on the lower side. Each slit 15 forms a pair of cuts 15 a and 15 a in the main body 11.

各切れ目１５ａは、端部１５ｂ，１５ｃ同士が互いにかみ合う形状になっており、ここでは、図４に示すように、スリット間溝部１３Ａ側の端部１５ｂが谷形になり、他の溝部１３Ｂ側の端部１５ｃが山形になっている。すなわち、各切れ目１５ａは、本体部１１の下方から見たときにＶ字状に形成されている。 Each cut 15a has a shape in which the end portions 15b and 15c are engaged with each other. Here, as shown in FIG. 4, the end portion 15b on the side of the inter-slit groove portion 13A has a valley shape, and the other groove portion 13B side. The end portion 15c of this is a mountain shape. That is, each cut 15 a is formed in a V shape when viewed from below the main body 11.

次に、この発明のグロメット１０の作用について説明する。 Next, the operation of the grommet 10 of the present invention will be described.

このグロメット１０を使用するには、まず、一方のスリット１５によって形成された一方の切れ目１５ａを広げ、一方の貫通孔１２を開く。そして、この広げられた貫通孔１２内に第一ハーネスＨ１の所定の部分を位置させた後、切れ目１５ａを閉じて一方の貫通孔１２に第一ハーネスＨ１を貫通させる。 In order to use this grommet 10, first, one cut 15 a formed by one slit 15 is widened, and one through hole 12 is opened. And after positioning the predetermined part of the 1st harness H1 in this expanded through-hole 12, the cut | interruption 15a is closed and the 1st harness H1 is penetrated to one through-hole 12. FIG.

次に、他方のスリット１５によって形成された他方の切れ目１５ａを開き、他方の貫通孔１２を開いて第二ハーネスＨ２を配置し、この他方の貫通孔１２に第二ハーネスＨ２を貫通させる。 Next, the other cut 15 a formed by the other slit 15 is opened, the other through hole 12 is opened, the second harness H 2 is disposed, and the second harness H 2 is passed through the other through hole 12.

このように、あらかじめ第一、第二ハーネスＨ１，Ｈ２をそれぞれグロメット１０に貫通させてから、このグロメット１０は、隔壁２に形成された凹所３が係合溝部１３に嵌着するようにこの凹所３内に押し込まれ、隔壁２に取り付けられる。 In this way, after the first and second harnesses H1 and H2 are passed through the grommets 10 in advance, the grommets 10 are formed so that the recesses 3 formed in the partition wall 2 are fitted into the engaging grooves 13. It is pushed into the recess 3 and attached to the partition wall 2.

このとき、グロメット１０の本体部１１は、凹所３の内側に密着しながら押し込まれるので、この本体部１１に側方からの押圧力が作用し、一対のスリット１５，１５によって形成された一対の切れ目１５ａ，１５ａは閉塞する。 At this time, the main body part 11 of the grommet 10 is pushed in close contact with the inside of the recess 3, so that a pressing force from the side acts on the main body part 11, and a pair formed by the pair of slits 15, 15. The cuts 15a and 15a are closed.

ここで、各切れ目１５ａは、端部１５ｂ，１５ｃ同士が互いにかみ合う形状になっているので、切れ目１５ａが閉塞した際に、この端部１５ｂ，１５ｃ同士がかみ合い、本体部１１のうち、スリット１５，１５の間に位置する部分が横ずれすることが防止される。 Here, each of the cuts 15a has a shape in which the end portions 15b and 15c are engaged with each other. Therefore, when the cut 15a is closed, the end portions 15b and 15c are engaged with each other. , 15 is prevented from shifting laterally.

特に、ここでは各切れ目１５ａが、本体部１１の下方から見たときにＶ字状に形成されているので、本体部１１の側方からの押圧力によってセンタリング作用が発生し、スリット間溝部１３Ａと他の溝部１３Ｂとがずれていた場合であっても、これを修正することができる。 In particular, since each of the cuts 15a is formed in a V shape when viewed from below the main body portion 11, a centering action is generated by the pressing force from the side of the main body portion 11, and the inter-slit groove portion 13A. Even if it is a case where other groove part 13B has shifted | deviated, this can be corrected.

これにより、スリット間溝部１３Ａと他の溝部１３Ｂとがずれてしまうことを防止でき、係合溝部１３を隔壁２に容易に係合させることができる。 Thereby, it can prevent that the groove part 13A between slits and the other groove part 13B shift | deviate, and the engagement groove part 13 can be easily engaged with the partition 2. FIG.

すなわち、このスリット１５により形成された本体部１１の切れ目１５ａを、端部１５ｂ，１５ｃが互いにかみ合う形状にした構成は、スリット間溝部１３Ａと隔壁２とを係合しやすくする易係合手段となっている。 That is, the configuration in which the cut 15a of the main body portion 11 formed by the slit 15 is in a shape in which the end portions 15b and 15c mesh with each other is easy engagement means that makes it easy to engage the inter-slit groove portion 13A and the partition wall 2. It has become.

また、スリット間溝部１３Ａの幅Ｗ１は、他の溝部１３Ｂの幅Ｗ２よりも広く形成され、隔壁２に形成された凹所３の厚みＴよりも大きくなっている。そのため、スリット間溝部１３Ａと他の溝部１３Ｂとがずれていたとしても、隔壁２をスリット間溝部１３Ａ内に挿入しやすく、係合溝部１３を隔壁２に容易に係合させることができる。 Further, the width W1 of the inter-slit groove 13A is formed wider than the width W2 of the other groove 13B, and is larger than the thickness T of the recess 3 formed in the partition wall 2. Therefore, even if the groove part 13A between slits and the other groove part 13B are shifted, the partition wall 2 can be easily inserted into the groove part 13A between slits, and the engagement groove part 13 can be easily engaged with the partition wall 2.

すなわち、このスリット間溝部１３Ａの幅Ｗ１を他の溝部１３Ｂの幅Ｗ２よりも広くする構成は、スリット間溝部１３Ａと隔壁２とを係合しやすくする易係合手段となっている。 That is, the configuration in which the width W1 of the inter-slit groove 13A is wider than the width W2 of the other groove 13B is an easy-engagement means that makes it easy to engage the inter-slit groove 13A and the partition wall 2.

そして、このスリット間溝部１３Ａの内側には、本体部１１の外周面１１ａからへこむに連れて次第に突出する傾斜面１３ｃが形成されている。そのため、隔壁２の凹所３は、この傾斜面１３ｃに案内されながらスリット間溝部１３Ａ内に挿入され、係合溝部１３を隔壁２にさらに容易に係合させることができる。 An inclined surface 13c is formed on the inner side of the inter-slit groove portion 13A. The inclined surface 13c gradually protrudes as it is recessed from the outer peripheral surface 11a of the main body portion 11. Therefore, the recess 3 of the partition wall 2 is inserted into the inter-slit groove portion 13A while being guided by the inclined surface 13c, and the engagement groove portion 13 can be more easily engaged with the partition wall 2.

すなわち、このスリット間溝部１３Ａの内側に本体部１１の外周面１１ａからへこむに連れて次第に突出する傾斜面１３ｃを形成した構成は、スリット間溝部１３Ａと隔壁２とを係合しやすくする易係合手段となっている。 That is, the configuration in which the inclined surface 13c that gradually protrudes from the outer peripheral surface 11a of the main body portion 11 is formed inside the inter-slit groove portion 13A facilitates engagement between the inter-slit groove portion 13A and the partition wall 2. It is a means.

さらに、上述の実施の形態では、本体部１１に形成された一対のスリット１５，１５が、本体部１１の下側に形成されている。 Furthermore, in the above-described embodiment, the pair of slits 15 and 15 formed in the main body portion 11 are formed on the lower side of the main body portion 11.

これにより、スリット１５，１５による本体部１１の切れ目１５ａ，１５ａが上方から見えにくくなり、グロメット１０の取付状態を見栄えよく仕上ることができる。 Thereby, the cuts 15a and 15a of the main body 11 due to the slits 15 and 15 become difficult to see from above, and the mounting state of the grommet 10 can be finished with a good appearance.

以上説明したように、本発明に係るグロメット１０は、本体部１１に外周面１１ａから一対の貫通孔１２，１２のそれぞれにまで達する一対のスリット１５，１５が係合溝部１３を横切る位置にそれぞれ形成されると共に、隣り合うスリット１５，１５間に位置する係合溝部１３であるスリット間溝部１３Ａと隔壁２とを係合させやすくする易係合手段が形成されている。 As described above, the grommet 10 according to the present invention is such that the pair of slits 15, 15 reaching the main body portion 11 from the outer peripheral surface 11 a to the pair of through holes 12, 12 respectively cross the engaging groove portion 13. In addition to being formed, an easy-engagement means is provided for facilitating engagement between the slit 2 and the inter-slit groove 13A, which is the engaging groove 13 located between the adjacent slits 15 and 15.

これにより、スリット間溝部１３Ａと隔壁２とを容易に係合することができ、このグロメット１０を隔壁２に取り付ける際の取付作業を容易にして、装着作業性を向上させることが可能となる。 Thereby, the groove part 13A between slits and the partition 2 can be easily engaged, and the attachment work at the time of attaching this grommet 10 to the partition 2 can be facilitated, and attachment workability | operativity can be improved.

Here, as shown in FIG. 8, the end portion 25b on the side of the inter-slit rib portion 24A has a valley shape, and other rib portions. The end portion 25c on the 24B side has a mountain shape. That is, each cut 25 a is formed in a V shape when viewed from above the main body 21.

次に、この実施例に係るグロメット２０の作用について説明する。 Next, the operation of the grommet 20 according to this embodiment will be described.

このグロメット２０を使用するには、あらかじめ第一、第二ハーネスＨ１，Ｈ２を貫通孔２２，２２にそれぞれ貫通させ、その後、本体部２１を隔壁２に形成された凹所３内に嵌着する。 In order to use this grommet 20, the first and second harnesses H 1 and H 2 are passed through the through holes 22 and 22 in advance, and then the main body 21 is fitted into the recess 3 formed in the partition wall 2. .

このとき、グロメット２０の本体部２１は、凹所３の内側に密着しながら押し込まれるので、この本体部２１に側方からの押圧力が作用し、一対のスリット２５，２５によって形成された一対の切れ目２５ａ，２５ａは閉塞する。 At this time, the main body portion 21 of the grommet 20 is pushed in close contact with the inside of the recess 3, so that a pressing force from the side acts on the main body portion 21, and a pair formed by the pair of slits 25, 25. The cuts 25a and 25a are closed.

ここで、各切れ目２５ａは、端部２５ｂ，２５ｃ同士が互いにかみ合う形状になっているので、切れ目２５ａが閉塞した際に、この端部２５ｂ，２５ｃがかみ合い、本体部２１のうち、スリット２５，２５の間に位置する部分が横ずれすることが防止される。 Here, since each cut 25a has a shape in which the end portions 25b and 25c are engaged with each other, when the cut 25a is closed, the end portions 25b and 25c are engaged, and the slit 25, The portion located between 25 is prevented from being laterally displaced.

これにより、スリット間リブ部２４Ａと他のリブ部２４Ｂとがずれてしまうことを防止でき、係合リブ部２４を隔壁２に沿った形にすることができる。そして、後述するように、ウェザーストリップ４の保持凹部５内にこの係合リブ部２４を挿入しやすくなり、係合リブ部２４をウェザーストリップ４に容易に係合させることができる。 Thereby, it can prevent that the rib part 24A between slits and the other rib part 24B shift | deviate, and the engagement rib part 24 can be made into the shape along the partition 2. FIG. As will be described later, the engagement rib portion 24 can be easily inserted into the holding recess 5 of the weather strip 4, and the engagement rib portion 24 can be easily engaged with the weather strip 4.

すなわち、このスリット２５により形成された本体部２１の切れ目２５ａを、端部２５ｂ，２５ｃが互いにかみ合う形状にした構成は、スリット間リブ部２４Ａとウェザーストリップ４とを係合しやすくする易係合手段となっている。 That is, the configuration in which the cut 25a of the main body portion 21 formed by the slit 25 is configured such that the end portions 25b and 25c mesh with each other facilitates engagement between the rib portion 24A between the slits and the weather strip 4. It is a means.

そして、本体部２１を凹所３内に完全に挿入すると、隔壁２の上端部２ａとグロメット２０の係合リブ部２４の先端部とはほぼ同じ高さとなる。 When the main body portion 21 is completely inserted into the recess 3, the upper end portion 2a of the partition wall 2 and the tip end portion of the engaging rib portion 24 of the grommet 20 are substantially the same height.

次に、ウェザーストリップ４を隔壁２に取り付ける。これは、隔壁２の上端部２ａに沿ってウェザーストリップ４の保持凹部５を押し付け、この保持凹部５内に上縁部２ａ及びグロメット２０の係合リブ部２４を嵌合させることで行われる。 Next, the weather strip 4 is attached to the partition wall 2. This is performed by pressing the holding recess 5 of the weather strip 4 along the upper end portion 2 a of the partition wall 2 and fitting the upper edge 2 a and the engaging rib portion 24 of the grommet 20 into the holding recess 5.

このとき、グロメット２０のスリット間リブ部２４Ａの厚みＴ１は、他のリブ部２４Ｂの厚みＴ２よりも薄くなるように形成され、ウェザーストリップ４の保持凹部５の開口幅Ｗよりも小さくなっている。そのため、スリット間リブ部２４Ａと他のリブ部２４Ｂとがずれていたとしても、スリット間リブ部２４Ａは保持凹部５内に挿入しやすくなり、係合リブ部２４をウェザーストリップ４に容易に係合させることができる。 At this time, the thickness T1 of the inter-slit rib portion 24A of the grommet 20 is formed to be thinner than the thickness T2 of the other rib portion 24B, and is smaller than the opening width W of the holding recess 5 of the weather strip 4. . Therefore, even if the inter-slit rib portion 24A and the other rib portion 24B are misaligned, the inter-slit rib portion 24A can be easily inserted into the holding recess 5, and the engaging rib portion 24 can be easily engaged with the weather strip 4. Can be combined.

すなわち、このスリット間リブ部２４Ａの厚みＴ１を他のリブ部２４Ｂの厚みＴ２よりも薄くする構成は、スリット間リブ部２４Ａとウェザーストリップ４とを係合しやすくする易係合手段となっている。 That is, the configuration in which the thickness T1 of the inter-slit rib portion 24A is made thinner than the thickness T2 of the other rib portions 24B is an easy engagement means that makes it easy to engage the inter-slit rib portion 24A and the weather strip 4. Yes.

さらに、上述の実施例では、このスリット間リブ部２４Ａは、先端部を先細り形状とする傾斜面２４ｃが形成されている。そのため、このスリット間リブ部２４Ａは、傾斜面２４ｃに案内されながら保持凹部５内に挿入され、係合リブ部２４をウェザーストリップ４にさらに容易に係合させることができる。 Further, in the above-described embodiment, the inter-slit rib portion 24A is formed with an inclined surface 24c having a tapered tip. Therefore, the inter-slit rib portion 24A is inserted into the holding recess 5 while being guided by the inclined surface 24c, and the engaging rib portion 24 can be more easily engaged with the weather strip 4.

すなわち、このスリット間リブ部２４Ａに、先端部を先細りとする傾斜面２４ｃを形成した構成は、スリット間リブ部２４Ａとウェザーストリップ４とを係合しやすくする易係合手段となっている。 That is, the configuration in which the inclined surface 24c having the tip end tapered is formed on the inter-slit rib portion 24A serves as an easy engagement means for facilitating the engagement between the inter-slit rib portion 24A and the weather strip 4.

以上説明したように、本発明に係るグロメット２０は、係合部が本体部２１の外周面２１ａから突出するリブ形状を呈していると共に、本体部２１に外周面２１ａから一対の貫通孔２２，２２のそれぞれにまで達する一対のスリット２５，２５が係合リブ部２４を横切る位置にそれぞれ形成され、隣り合うスリット２５，２５間に位置する係合リブ部２４であるスリット間リブ部２４Ａとウェザーストリップ４とを係合させやすくする易係合手段が形成されている。 As described above, the grommet 20 according to the present invention has a rib shape in which the engaging portion protrudes from the outer peripheral surface 21a of the main body portion 21 and the pair of through holes 22 from the outer peripheral surface 21a to the main body portion 21. A pair of slits 25, 25 reaching each of the ribs 22 are formed at positions crossing the engagement ribs 24, and the inter-slit ribs 24 A that are the engagement ribs 24 positioned between the adjacent slits 25, 25 and the weather. Easy engagement means for facilitating engagement with the strip 4 is formed.

これにより、スリット間リブ部２４Ａとウェザーストリップ４とを容易に係合することができる。 Thereby, the rib part 24A between slits and the weather strip 4 can be easily engaged.

以上、この発明にかかる実施の形態を図面により詳述してきたが、具体的な構成は上述の実施の形態に限らない。この発明の要旨を逸脱しない範囲の設計の変更等はこの発明に含まれる。 As mentioned above, although embodiment concerning this invention has been explained in full detail with drawing, a concrete structure is not restricted to the above-mentioned embodiment. Design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.

例えば、上述の易係合手段に限らず、係合溝部１３と隔壁２との間に生じる摩擦抵抗を低減させ、互いに滑りやすくすることで係合しやすくする易係合手段であってもよい。 For example, not only the above-described easy engagement means, but also easy engagement means that makes it easier to engage by reducing frictional resistance generated between the engagement groove 13 and the partition wall 2 and making them mutually slippery. .

また、易係合手段として、スリット１５によって形成された切れ目１５ａの端部１５ｂ，１５ｃに互いに引き合う方向の磁性を持たせる構成であってもよい。この場合であっても、本体部１１の横ずれを防止してスリット間溝部１３Ａがずれてしまうことを防止し、係合溝部１３と隔壁２とを係合しやすくすることができる。 Moreover, the structure which gives the magnetism of the direction attracted to the edge parts 15b and 15c of the cut | interruption 15a formed by the slit 15 as an easy engagement means may be sufficient. Even in this case, the lateral displacement of the main body 11 can be prevented to prevent the inter-slit groove 13A from being displaced, and the engagement groove 13 and the partition wall 2 can be easily engaged.

さらに、上述の実施の形態及び実施例では、グロメット１０，２０は、一対のハーネスＨ１，Ｈ２を保持しているが、二つ以上の任意の数であってもよい。この場合、ハーネスの数に合わせて貫通孔及びスリットを本体部に形成する。 Furthermore, in the above-described embodiment and examples, the grommets 10 and 20 hold the pair of harnesses H1 and H2, but may be any number of two or more. In this case, through holes and slits are formed in the main body according to the number of harnesses.

また、上述の実施の形態では、一対の貫通孔１２，１２をグロメット１０の取付方向に直交する方向に並べて形成すると共に、一対のスリット１５，１５をこの取付方向に沿って延在しているが、これに限らず、例えば、複数の貫通孔をグロメットの取付方向に沿って並ぶように形成し、複数のスリットをこの取付方向と直交する方向に沿って延在してもよい。 In the above-described embodiment, the pair of through holes 12 and 12 are formed side by side in a direction orthogonal to the mounting direction of the grommet 10, and the pair of slits 15 and 15 extend along the mounting direction. However, the present invention is not limited thereto, and for example, a plurality of through holes may be formed so as to be aligned along the mounting direction of the grommet, and the plurality of slits may extend along a direction orthogonal to the mounting direction.

この場合であっても、本体部に易係合手段を設けることにより、隣接するスリット間に位置する係合部と被取付部材とを係合させやすくすることができる。 Even in this case, it is possible to easily engage the engagement member and the attached member located between the adjacent slits by providing the body portion with easy engagement means.

また、上述のグロメット１０，２０は、それぞれエンジンルーム１内に設けられた隔壁２とウェザーストリップ４との間に取り付けられているが、ダッシュパネル等の車体パネル等に取り付けられるものであってもよい。 Moreover, although the above-mentioned grommets 10 and 20 are each attached between the partition 2 and the weather strip 4 provided in the engine room 1, they may be attached to a vehicle panel such as a dash panel. Good.

さらに、スリット１５によって形成された本体部１１の切れ目１５ａは、互いの端部１５ｂ，１５ｃがかみ合う形状であればよいので、例えば、図１０（ａ）に示す切れ目１５ｘのように下方から見たときに波形状であったり、図１０（ｂ）に示す切れ目１５ｙのように下方から見たときに一部が半円状に湾曲していたり、図１０（ｃ）に示す切れ目１５ｚのように下方から見たときに角型に屈曲していたりしてもよい。 Furthermore, since the cut 15a of the main body 11 formed by the slit 15 only needs to have a shape in which the end portions 15b and 15c are engaged with each other, for example, the cut 15a is viewed from below like a cut 15x shown in FIG. Sometimes it has a wave shape, or when it is viewed from below like a cut 15y shown in FIG. 10 (b), it is partially curved in a semicircular shape, or like a cut 15z shown in FIG. 10 (c). It may be bent into a square shape when viewed from below.
