収容部１１０の第１壁部１１１、第２壁部１１２及び第３壁部１１３と蓋部１２０とにより周壁部１０１が構成される。蓋部１２０が収容部１１０に取り付けられると、周壁部１０１の第４壁部１１４側のＸ軸方向の端部は閉塞される。一方、蓋部１２０が取り付けられても、周壁部１０１の第４壁部１１４とは反対側のＸ軸方向の端部は開放されている。すなわち、周壁部１０１には、この端部に開口１０２が設けられている。 The peripheral wall 101 is constituted by the first wall 111 , the second wall 112 , and the third wall 113 of the accommodating portion 110 and the lid 120 . When the lid part 120 is attached to the housing part 110, the end of the peripheral wall part 101 on the fourth wall part 114 side in the X-axis direction is closed. On the other hand, even if the lid part 120 is attached, the end of the peripheral wall part 101 in the X-axis direction opposite to the fourth wall part 114 is open. That is, the peripheral wall portion 101 is provided with an opening 102 at this end.

収容部１１０は、第３壁部１１３の第１主面１１３Ａから蓋部１２０の第１主面１２０Ａに向けて突出する突出部１３０を有する。突出部１３０は第３壁部１１３と一体に形成されている。例えば、突出部１３０は円柱状の形状を有し、Ｘ軸方向からの平面視で突出部１３０の形状は円形状である。突出部１３０には、突出部１３０が突出する方向で、ここではＸ軸方向で突出部１３０を貫通する貫通孔１３０Ｘが形成されている。貫通孔１３０Ｘは第３孔の一例である。 The accommodating portion 110 has a protruding portion 130 that protrudes from the first main surface 113A of the third wall portion 113 toward the first main surface 120A of the lid portion 120. The protruding portion 130 is formed integrally with the third wall portion 113. For example, the protrusion 130 has a cylindrical shape, and the protrusion 130 has a circular shape when viewed in plan from the X-axis direction. The protrusion 130 is formed with a through hole 130X that penetrates the protrusion 130 in the direction in which the protrusion 130 protrudes, here in the X-axis direction. The through hole 130X is an example of a third hole.

図４に示すように、開口１０２側からのＺ軸方向の平面視で、開口１０２は突出部１３０により２分割されている。すなわち、開口１０２は、開口１０２側からのＺ軸方向の平面視で、突出部１３０と第１壁部１１１との間のサブ開口１０２Ａと、突出部１３０と第２壁部１１２との間のサブ開口１０２Ｂとを有する。 As shown in FIG. 4, the opening 102 is divided into two by the protrusion 130 when viewed from the opening 102 side in the Z-axis direction. That is, the opening 102 has a sub-opening 102A between the protrusion 130 and the first wall 111 and a sub-opening 102A between the protrusion 130 and the second wall 112 in a plan view from the opening 102 side in the Z-axis direction. It has a sub-opening 102B.

第３壁部１１３に、Ｚ軸方向において開口１０２から離間して、第３壁部１１３を厚さ方向で、ここではＸ軸方向で貫通する一対の貫通孔１１３Ｘが形成されている。突出部１３０は、周壁部１０１の両端部を結ぶ方向、ここではＺ軸方向において、一対の貫通孔１１３Ｘと開口１０２との間に位置する。詳細は後述するが、周壁部１０１の内側の空間に複数本のケーブルが収容され、これら複数本のケーブルを結束した結束部材が一対の貫通孔１１３Ｘに挿通され、複数本のケーブルが周壁部１０１に固定される。貫通孔１１３Ｘは第１孔の一例である。 A pair of through holes 113X are formed in the third wall portion 113, spaced apart from the opening 102 in the Z-axis direction, and passing through the third wall portion 113 in the thickness direction, here in the X-axis direction. The protrusion 130 is located between the pair of through holes 113X and the opening 102 in the direction connecting both ends of the peripheral wall 101, here in the Z-axis direction. Although details will be described later, a plurality of cables are accommodated in the space inside the peripheral wall 101, and a binding member that binds the plurality of cables is inserted through the pair of through holes 113X, and the plurality of cables are housed in the space inside the peripheral wall 101. Fixed. The through hole 113X is an example of a first hole.

第４壁部１１４の第２主面１１４Ｂに、ジョイントボックス１００を家屋の梁、天井等に固定するための係止部１１５が、第１壁部１１１、第２壁部１１２、第３壁部１１３及び第４壁部１１４と一体に形成されている。係止部１１５には、係止部１１５を、例えばＸ軸方向に貫通する取付穴１１５Ｘが形成されている。 A locking part 115 for fixing the joint box 100 to a beam, a ceiling, etc. of a house is provided on the second main surface 114B of the fourth wall part 114, and the first wall part 111, the second wall part 112, and the third wall part 113 and the fourth wall portion 114. The locking portion 115 is formed with a mounting hole 115X that passes through the locking portion 115 in, for example, the X-axis direction.

詳細は後述するが、ジョイントボックス１００は次のような効果を有する。ジョイントボックス１００内に収容される複数本のケーブルは、貫通孔１１３Ｘに挿通される結束部材により結束されて周壁部１０１に固定され、開口１０２からジョイントボックス１００の外部に引き出される。Ｚ軸方向において、貫通孔１１３Ｘと開口１０２との間に突出部１３０が設けられているため、ケーブルは突出部１３０に接触し、ケーブルと突出部１３０との間に摩擦力が生じる。このため、外部からケーブルに力が作用しても、その力は結束部材だけでなく突出部１３０にも作用する。この結果、結束部材にかかる荷重を緩和できる。したがって、結束部材の伸びや切断を抑制できる。 Although details will be described later, the joint box 100 has the following effects. A plurality of cables housed in the joint box 100 are bound by a binding member inserted through the through hole 113X, fixed to the peripheral wall 101, and pulled out from the joint box 100 through the opening 102. Since the protrusion 130 is provided between the through hole 113X and the opening 102 in the Z-axis direction, the cable comes into contact with the protrusion 130, and a frictional force is generated between the cable and the protrusion 130. Therefore, even if a force is applied to the cable from the outside, the force acts not only on the binding member but also on the protrusion 130. As a result, the load on the binding member can be alleviated. Therefore, stretching and cutting of the binding member can be suppressed.

なお、ジョイントボックス１００の形状は直方体状でなくてもよい。例えば、ジョイントボックス１００が、直方体の一部の隅にＲ加工が施された形状を有していてもよい。 Note that the shape of the joint box 100 does not have to be a rectangular parallelepiped. For example, the joint box 100 may have a rectangular parallelepiped shape with rounded corners at some corners.

（第２実施形態）
第２実施形態は、ユニットケーブルに関する。図５は、第２実施形態に係るユニットケーブルを示す正面図である。図６は、第２実施形態に係るユニットケーブルを示す下面図である。図５では、収容部１１０内のケーブルの配置を示すため、蓋部１２０の図示が省略されている。 (Second embodiment)
The second embodiment relates to a unit cable. FIG. 5 is a front view showing a unit cable according to the second embodiment. FIG. 6 is a bottom view showing the unit cable according to the second embodiment. In FIG. 5, illustration of the lid part 120 is omitted in order to show the arrangement of the cables within the housing part 110.

図５及び図６に示すように、第２実施形態に係るユニットケーブル２００は、第１実施形態に係るジョイントボックス１００と、周壁部１０１の内側の空間に収容された複数本、この例では６本のケーブル２１０とを有する。６本のケーブル２１０には、例えばＶＶＦ（vinyl insulated vinyl sheathed flat-type cable）ケーブルが含まれる。６本のケーブル２１０にＥＥＦ（polyethylene insulated polyethylene sheathed flat-type cable）ケーブルが含まれてもよい。６本のケーブル２１０に接地線付きＶＶＦケーブル又は接地線付きＥＥＦケーブルが含まれてもよい。６本のケーブル２１０にＣｕクラッドＡｌ線が含まれてもよい。６本のケーブル２１０は、互いに平行に配置しており、６本のケーブル２１０の電線は複数個、ここでは４個の電線コネクタ２２０で回路結線されている。電線コネクタ２２０としては、差込形コネクタや、リングスリーブと絶縁チューブとの組合せを採用することができる。 As shown in FIGS. 5 and 6, a plurality of unit cables 200 according to the second embodiment are housed in a space inside the joint box 100 and the peripheral wall 101 according to the first embodiment. It has a cable 210 of this type. The six cables 210 include, for example, VVF (vinyl insulated vinyl sheathed flat-type cable) cables. The six cables 210 may include EEF (polyethylene insulated polyethylene sheathed flat-type cable) cables. The six cables 210 may include a VVF cable with a ground wire or an EEF cable with a ground wire. Six cables 210 may include Cu-clad Al wires. The six cables 210 are arranged parallel to each other, and the electric wires of the six cables 210 are connected to a circuit using a plurality of electric wire connectors 220, here four electric wire connectors 220. As the wire connector 220, a plug-in connector or a combination of a ring sleeve and an insulating tube can be adopted.

ユニットケーブル２００は、６本のケーブル２１０を結束する結束部材２３０を有する。結束部材２３０は、６本のケーブル２１０を結束しつつ、第３壁部１１３に形成された一対の貫通孔１１３Ｘに挿通され、周壁部１０１の外側で締められている。結束部材２３０によって６本のケーブル２１０が結束されているため、各ケーブル２１０は少なくとも１本の他のケーブル２１０に接触する。このようにして、６本のケーブル２１０は結束部材２３０によって結束され、周壁部１０１に固定されている。結束部材２３０は第１結束部材の一例である。 The unit cable 200 has a binding member 230 that binds the six cables 210 together. The binding member 230 is inserted into a pair of through holes 113X formed in the third wall portion 113 while binding the six cables 210, and is tightened on the outside of the peripheral wall portion 101. Since the six cables 210 are bundled by the binding member 230, each cable 210 contacts at least one other cable 210. In this way, the six cables 210 are bound by the binding member 230 and fixed to the peripheral wall 101. Binding member 230 is an example of a first binding member.

上述のように、Ｚ軸方向において、一対の貫通孔１１３Ｘと開口１０２との間に突出部１３０が設けられている。６本のケーブル２１０は、Ｚ軸方向において、結束部材２３０が４個の電線コネクタ２２０と突出部１３０との間に位置するように収容部１１０に配置される。６本のケーブル２１０は、例えば３本ずつ２つの組に分けられ、一方の組が開口１０２のサブ開口１０２Ａを通じてジョイントボックス１００の外部に引き出され、他方の組がサブ開口１０２Ｂを通じてジョイントボックス１００の外部に引き出されている。突出部１３０を基準として、６本のケーブル２１０は開口１０２とは反対側で結束部材２３０により結束されている。このため、各ケーブル２１０には、Ｙ軸方向で突出部１３０に向かう力が作用する。従って、３本ずつの各組において、少なくとも１本のケーブル２１０が突出部１３０に直接接触し、突出部１３０に押し付けられている。従って、当該ケーブル２１０と突出部１３０との間には大きな摩擦力が生じる。また、突出部１３０に直接接触しないケーブル２１０にも、他のケーブル２１０を介して突出部１３０との間に大きな摩擦力が生じる。 As described above, the protrusion 130 is provided between the pair of through holes 113X and the opening 102 in the Z-axis direction. The six cables 210 are arranged in the housing section 110 such that the binding member 230 is located between the four wire connectors 220 and the protrusion 130 in the Z-axis direction. The six cables 210 are divided into two sets of three cables each, for example, one set is pulled out of the joint box 100 through the sub-opening 102A of the opening 102, and the other set is pulled out of the joint box 100 through the sub-opening 102B. being pulled outside. With the protrusion 130 as a reference, the six cables 210 are bound together by a binding member 230 on the opposite side of the opening 102 . Therefore, a force directed toward the protrusion 130 in the Y-axis direction acts on each cable 210. Thus, in each set of three, at least one cable 210 is in direct contact with and pressed against the protrusion 130 . Therefore, a large frictional force is generated between the cable 210 and the protrusion 130. Furthermore, a large frictional force is generated between the cable 210 that does not directly contact the protrusion 130 and the protrusion 130 via another cable 210 .

従って、ユニットケーブル２００において、６本のケーブル２１０のいずれかにジョイントボックス１００から引き抜く方向の力が作用したとしても、当該ケーブル２１０には、突出部１３０との間の大きな摩擦力が直接的又は間接的に逆向き作用する。このため、当該ケーブル２１０をジョイントボックス１００から抜けにくくすることができる。また、この摩擦力によって、結束部材２３０に作用する力が低減される。従って、結束部材２３０の破断を抑制することもできる。 Therefore, in the unit cable 200, even if a force in the direction of pulling it out from the joint box 100 acts on any of the six cables 210, the cable 210 is directly affected by a large frictional force with the protrusion 130 or It indirectly works in the opposite direction. Therefore, the cable 210 can be made difficult to come off from the joint box 100. Moreover, this frictional force reduces the force acting on the binding member 230. Therefore, breakage of the binding member 230 can also be suppressed.

突出部１３０が、第１壁部１１１、第２壁部１１２及び第３壁部１１３を備えた収容部１１０に設けられているため、ユニットケーブル２００を組み立てる際に、６本のケーブル２１０を所定の位置に配置させやすい。ただし、突出部１３０は、収容部１１０ではなく、蓋部１２０に設けられていてもよい。すなわち、突出部１３０が蓋部１２０と一体に形成されていてもよい。この場合、例えば、突出部１３０は蓋部１２０の第１主面１２０Ａから第３壁部１１３の第１主面１１３Ａに向けて突出する。収容部１１０及び蓋部１２０の形状によっては、突出部１３０が蓋部１２０に設けられている方が、収容部１１０及び蓋部１２０を形成しやすいことがある。 Because the protrusion 130 is provided in the storage section 110 having the first wall section 111, the second wall section 112, and the third wall section 113, it is easy to arrange the six cables 210 in the predetermined positions when assembling the unit cable 200. However, the protrusion 130 may be provided in the lid section 120 instead of the storage section 110. That is, the protrusion 130 may be formed integrally with the lid section 120. In this case, for example, the protrusion 130 protrudes from the first main surface 120A of the lid section 120 toward the first main surface 113A of the third wall section 113. Depending on the shapes of the storage section 110 and the lid section 120, it may be easier to form the storage section 110 and the lid section 120 if the protrusion 130 is provided in the lid section 120.

第３壁部１１３に一対の貫通孔１１３Ｘが形成されているため、結束部材２３０を環状にして周壁部１０１に固定しやすい。 Since the pair of through holes 113X are formed in the third wall portion 113, it is easy to make the binding member 230 into an annular shape and fix it to the peripheral wall portion 101.

周壁部１０１の開口１０２とは反対側の端部が第４壁部１１４により閉塞されているため、周壁部１０１の内側の空間への異物の侵入を抑制しやすい。 The end of the peripheral wall portion 101 opposite the opening 102 is blocked by the fourth wall portion 114, making it easier to prevent foreign matter from entering the space inside the peripheral wall portion 101.

ジョイントボックス１００が収容部１１０と蓋部１２０とを備えているため、ケーブル２１０をジョイントボックス１００内に収容しやすく、結束部材２３０をケーブル２１０に取り付けやすい。 Since the joint box 100 includes the housing part 110 and the lid part 120, the cable 210 can be easily stored in the joint box 100, and the binding member 230 can be easily attached to the cable 210.

Ｙ軸方向において、サブ開口１０２Ａを通じて引き出されるケーブル２１０とサブ開口１０２Ｂを通じて引き出されるケーブル２１０とにより突出部１３０が挟まれているため、より多くのケーブル２１０を突出部１３０に接触させやすい。 Since the protrusion 130 is sandwiched between the cable 210 drawn out through the sub-opening 102A and the cable 210 drawn out through the sub-opening 102B in the Y-axis direction, it is easy to bring more cables 210 into contact with the protrusion 130.

６本のケーブル２１０に、ＶＶＦケーブル、ＥＥＦケーブルが含まれていてもよい。６本のケーブル２１０に、接地線付きＶＶＦケーブル、接地線付きＥＥＦケーブルが含まれていてもよい。接地線付きＶＶＦケーブルや接地線付きＥＥＦケーブルは、例えば特開２０１７－１８３１０３号公報、特開２０１７－２２０３１７号公報、特開２０１９－３３０４９号公報、特開２０１９－３３０５０号公報、特開２０１４－２２００７３号公報、特開２０１３－１５２９３６号公報、特開２０１１－１８１２３１号公報に開示されているが、これらに開示されている接地線付きＶＶＦケーブルや接地線付きＥＥＦケーブルに限定されない。６本のケーブル２１０は、少なくともその１本が、ＣｕクラッドＡｌ線の導体を含んでいてもよい。ＣｕクラッドＡｌ線を用いた平型ケーブルは例えば特開２０１８－４５８５５号公報、特開２０１５－１０３３６６号公報に開示されているが、これらに開示されているＣｕクラッドＡｌ線に限定されない。 The six cables 210 may include a VVF cable and an EEF cable. The six cables 210 may include a VVF cable with a grounding wire and an EEF cable with a grounding wire. VVF cables with grounding wires and EEF cables with grounding wires are disclosed in, for example, JP-A No. 2017-183103, JP-A No. 2017-220317, JP-A No. 2019-33049, JP-A No. 2019-33050, and JP-A No. 2014- The cables are disclosed in JP-A No. 220073, JP-A No. 2013-152936, and JP-A No. 2011-181231, but are not limited to the VVF cable with a grounding wire or the EEF cable with a grounding wire disclosed therein. At least one of the six cables 210 may include a Cu-clad Al wire conductor. Flat cables using Cu-clad Al wires are disclosed in, for example, JP-A-2018-45855 and JP-A-2015-103366, but the present invention is not limited to the Cu-clad Al wire disclosed in these publications.

ここで、ユニットケーブル２００の設置例について説明する。図７は、第２実施形態に係るユニットケーブルの設置例を示す図である。 Here, an installation example of the unit cable 200 will be described. FIG. 7 is a diagram showing an installation example of the unit cable according to the second embodiment.

ユニットケーブル２００を家屋に設置する際には、例えば、ビスやボルトが取付穴１１５Ｘを通るように、ユニットケーブル２００が梁や天井に対してビスやボルトで取り付けられる。その後、必要に応じて、他のビスやボルトが貫通孔１３０Ｘを通るように、ユニットケーブル２００が梁や天井に対してビスやボルトで取り付けられる。なお、貫通孔１３０Ｘの内面に雌ねじを形成して置き、雄ねじを螺合させてもよい。このようにして、ユニットケーブル２００を家屋に固定する。その上で、図７に示すように、サブ開口１０２Ａを通じて引き出されたケーブル２１０は、第２壁部１１２側に向かうようにして敷設される。同様に、サブ開口１０２Ｂを通じて引き出されたケーブル２１０は、第１壁部１１１側に向かうようにして敷設される。これは、ケーブル２１０と突出部１３０との接触面積を大きく確保し、より大きな摩擦力を得るためである。 When the unit cable 200 is installed in a house, for example, the unit cable 200 is attached to a beam or ceiling with a screw or bolt so that the screw or bolt passes through the mounting hole 115X. After that, if necessary, the unit cable 200 is attached to a beam or ceiling with a screw or bolt so that another screw or bolt passes through the through hole 130X. Note that a female thread may be formed on the inner surface of the through hole 130X and a male thread may be screwed into it. In this way, the unit cable 200 is fixed to the house. Then, as shown in FIG. 7, the cable 210 drawn out through the sub opening 102A is laid so as to face the second wall portion 112 side. Similarly, the cable 210 drawn out through the sub opening 102B is laid so as to face the first wall portion 111 side. This is to ensure a large contact area between the cable 210 and the protruding portion 130 and to obtain a larger frictional force.

（変形例）
Ｚ軸方向において、６本のケーブル２１０が２箇所で結束させて周壁部１０１に固定されてもよい。図８は、第１実施形態の変形例に係るジョイントボックスの収容部を示す正面図である。図９は、第２実施形態の変形例に係るユニットケーブルを示す正面図である。図９では、収容部１１０内のケーブルの配置を示すため、蓋部１２０の図示が省略されている。 (Modified example)
In the Z-axis direction, six cables 210 may be tied together at two locations and fixed to the peripheral wall portion 101. FIG. 8 is a front view showing the accommodating part of the joint box according to a modification of the first embodiment. FIG. 9 is a front view showing a unit cable according to a modification of the second embodiment. In FIG. 9, illustration of the lid part 120 is omitted in order to show the arrangement of the cables within the housing part 110.

この変形例では、図８に示すように、第３壁部１１３に、Ｚ軸方向において開口１０２から離間して、第３壁部１１３を厚さ方向で、ここではＸ軸方向で貫通する一対の貫通孔１１３Ｙが形成されている。一対の貫通孔１１３Ｘは、Ｚ軸方向において、一対の貫通孔１１３Ｙと突出部１３０との間に位置する。６本のケーブル２１０は、結束部材２３０だけでなく、結束部材２４０によっても結束されている。結束部材２４０は、一対の貫通孔１１３Ｙに挿通され、周壁部１０１の外側で締められている。貫通孔１１３Ｙは第２孔の一例であり、結束部材２４０は第２結束部材の一例である。 In this modified example, as shown in FIG. 8, a pair of through holes 113Y are formed in the third wall portion 113, which are spaced apart from the opening 102 in the Z-axis direction and penetrate the third wall portion 113 in the thickness direction, here in the X-axis direction. The pair of through holes 113X are located between the pair of through holes 113Y and the protrusion portion 130 in the Z-axis direction. The six cables 210 are bound not only by the binding member 230 but also by the binding member 240. The binding member 240 is inserted through the pair of through holes 113Y and fastened on the outside of the peripheral wall portion 101. The through holes 113Y are an example of a second hole, and the binding member 240 is an example of a second binding member.

この変形例によれば、６本のケーブル２１０をより強固に結束し、周壁部１０１により強固に固定することができる。また、第３壁部１１３に一対の貫通孔１１３Ｙが形成されているため、結束部材２４０を環状にして周壁部１０１に固定しやすい。 According to this modification, the six cables 210 can be more firmly tied together and more firmly fixed to the peripheral wall portion 101. Further, since the pair of through holes 113Y are formed in the third wall portion 113, it is easy to make the binding member 240 into an annular shape and fix it to the peripheral wall portion 101.

６本のケーブル２１０は、結束部材２３０によって結束部材２４０よりも密に結束されていてもよく、結束部材２４０によって結束部材２３０よりも密に結束されていてもよい。結束部材２３０によって結束部材２４０よりも密に結束されている場合、つまり、結束部材２３０が形成する環の面積が、結束部材２４０が形成する環の面積よりも小さい場合、ケーブル２１０をより強固に突出部１３０に接触させやすい。結束部材２４０によって結束部材２３０よりも密に結束されている場合、つまり、結束部材２４０が形成する環の面積が、結束部材２３０が形成する環の面積よりも小さい場合、ケーブル２１０を収容部１１０に収容させやすい。 The six cables 210 may be bound by the binding member 230 more tightly than the binding member 240, or may be bound by the binding member 240 more tightly than the binding member 230. When the cables 210 are bound by the binding member 230 more tightly than the binding member 240, that is, when the area of the ring formed by the binding member 230 is smaller than the area of the ring formed by the binding member 240, it is easier to make the cables 210 contact the protrusion 130 more firmly. When the cables 210 are bound by the binding member 240 more tightly than the binding member 230, that is, when the area of the ring formed by the binding member 240 is smaller than the area of the ring formed by the binding member 230, it is easier to accommodate the cables 210 in the accommodation section 110.

なお、結束部材２３０及び２４０は、６本のケーブル２１０のすべてを結束しているが、６本のケーブル２１０を複数の組に分け、結束部材２３０又は２４０よりも開口１０２から離間する位置で各組を結束する他の結束部材が含まれてもよい。例えば、サブ開口１０２Ａを通じて引き出される３本のケーブル２１０が結束部材で結束され、サブ開口１０２Ｂを通じて引き出される３本のケーブル２１０が結束部材で結束され、これらがまとめて結束部材２３０及び２４０により結束されてもよい。 Although the binding members 230 and 240 bind all six cables 210, the six cables 210 are divided into a plurality of groups, and each cable is tied at a position farther from the opening 102 than the binding members 230 or 240. Other binding members may be included to bind the sets. For example, three cables 210 pulled out through the sub-opening 102A are bundled with a binding member, three cables 210 pulled out through the sub-opening 102B are bundled with a binding member, and these are bundled together with binding members 230 and 240. It's okay.

突出部１３０の側面に、ケーブル２１０との間の摩擦係数を高めるための表面処理が施されていてもよい。摩擦力をより強化することができる。 The side surface of the protrusion 130 may be subjected to surface treatment to increase the coefficient of friction between the protrusion 130 and the cable 210. Frictional force can be further strengthened.

突出部１３０の形状は特に限定されない。例えば、突出部１３０が四角柱状の形状を有してもよい。 The shape of the protrusion 130 is not particularly limited. For example, the protrusion 130 may have a quadrangular prism shape.
