Description

本発明は、締結構造に関するものである。   The present invention relates to a fastening structure.

従来の薄板の締結構造では、締結される部材が薄過ぎる場合には、締結される薄板が、薄板同士を締結するスクリューの不完全ねじ部が形成される位置に入ってしまい、スクリューが空回りする虞があった。この場合、スクリューによって薄板同士を締結するのが困難なものとなっていた。そこで、従来の薄板の締結構造では、薄板の締付穴を突出させているものがある。例えば、特許文献1では、締結する2枚の薄板の双方に皿状絞り部を設け、皿状絞り部同士を重ねた状態でスクリューによって薄板同士を締結している。これにより、締結穴がスクリューの不完全ねじ部に入ることを抑制できるので、薄板同士を締結することができる。   In the conventional thin plate fastening structure, when a member to be fastened is too thin, the thin plate to be fastened enters a position where an incomplete screw portion of a screw for fastening the thin plates is formed, and the screw is idle. There was a fear. In this case, it has been difficult to fasten the thin plates with a screw. Thus, some conventional thin plate fastening structures have a thin plate with a tightening hole protruding therefrom. For example, in Patent Document 1, a plate-shaped diaphragm portion is provided on both of the two thin plates to be fastened, and the thin plates are fastened with screws in a state where the plate-shaped diaphragm portions are overlapped with each other. Thereby, since it can suppress that a fastening hole enters into the incomplete thread part of a screw, thin plates can be fastened.

しかしながら、特許文献1に記載の締結構造では、締結する2枚の薄板の双方に皿状絞り部を形成し、これらを重ね合わせているため、製造が困難になる虞がある。つまり、2枚の薄板同士を締結する際に皿状絞り部同士を重ねるため、皿状絞り部同士の精度を高くする必要がある。また、特許文献1に記載された実施形態2においても同様に、一方の薄板に形成された皿状絞り部の内側に他方の薄板に形成されたバーリングを入れるため、皿状絞り部とバーリングとの双方の突出高さの精度を高くする必要がある。このため、製造が困難になる虞があり、製造コストが向上する虞があった。   However, in the fastening structure described in Patent Document 1, since the plate-shaped restricting portions are formed on both of the two thin plates to be fastened and these are overlapped, there is a possibility that the manufacture becomes difficult. That is, when the two thin plates are fastened to each other, the plate-shaped diaphragm portions are overlapped with each other, so that it is necessary to increase the accuracy of the plate-shaped diaphragm portions. Similarly, in Embodiment 2 described in Patent Document 1, in order to put the burring formed on the other thin plate inside the dish-shaped throttle portion formed on one thin plate, It is necessary to increase the accuracy of the protruding heights of both. For this reason, there exists a possibility that manufacture may become difficult and there exists a possibility that manufacturing cost may improve.

Note that the present invention is not limited to the embodiments. In addition, constituent elements in the embodiments described below include those that can be easily assumed by those skilled in the art or those that are substantially the same.

(実施の形態)
図1は、実施の形態に係る締結構造を有する薄板の要部断面図である。同図に示す締結部材である薄板1は、例えば、DVD(Digital Versatile Disk)への記録や再生を行なうDVDレコーダなどの映像機器や、CD(Compact Disk)の再生を行なうCDプレーヤなどの音響機器などの、構造部材として設けられている。この薄板1は、金属材料からなる薄い板状の形状で形成されており、また、2枚の薄板1同士が締結可能になっている。この2枚の薄板1のうち、一方の薄板1は、貫通孔側薄板5となっており、他方の薄板1は螺孔側薄板10となっている。このうち、貫通孔側薄板5には、当該貫通孔側薄板5を貫通する孔である貫通孔6が形成されている。
(Embodiment)
FIG. 1 is a cross-sectional view of a main part of a thin plate having a fastening structure according to an embodiment. The thin plate 1 as a fastening member shown in the figure is, for example, a video device such as a DVD recorder for recording or reproducing on a DVD (Digital Versatile Disk), or an audio device such as a CD player for reproducing a CD (Compact Disk). It is provided as a structural member. The thin plate 1 is formed in a thin plate shape made of a metal material, and two thin plates 1 can be fastened together. Of the two thin plates 1, one thin plate 1 is a through hole side thin plate 5, and the other thin plate 1 is a screw hole side thin plate 10. Among these, the through-hole side thin plate 5 is formed with a through-hole 6 that is a hole penetrating the through-hole side thin plate 5.

また、螺孔側薄板10には、螺孔側薄板10の厚さ方向に突出した突出部12が形成されている。この突出部12は、螺孔側薄板10のうち、平坦な板状の形状で形成されている平面部11から、当該平面部11の厚さ方向に突出しており、また、螺孔側薄板10が金属材料からなる薄い板状の形状で形成されていることにより、突出部12は、弾力性を有している。また、突出部12は、平面部11の厚さ方向が軸方向となり、平面部11から、当該平面部11の厚さ方向に離れるに従って径が小さくなる略円錐形の一部の形状で形成されている。また、この突出部12は、当該突出部12が突出している方向における端部に、前記平面部11とほぼ平行な平面で形成された突出部平面部16を有している。さらに、突出部12は、平面部11から離れる方向の端部に位置する突出部平面部16に、バーリング部13を有している。このバーリング部13は、突出部12が突出している方向に突出部平面部16から突出しており、これらの突出部平面部16とバーリング部13とは、突出部12が有する補強部として設けられている。即ち、補強部はバーリング部13を有しており、突出部12は、補強部である突出部平面部16とバーリング部13とによって補強されて剛性が高くなっている。このバーリング部13は、略円筒形の形状で形成されており、円筒形の軸方向と突出部12の形状である略円錐形の軸方向が同一方向となる向きで、突出部12の先端に形成されている。また、バーリング部13は略円筒形の形状で形成されているため、バーリング部13の内側には、螺孔側薄板10の厚さ方向の孔が形成されており、この孔は、螺合部である下孔14となっている。   Further, the screw hole side thin plate 10 is formed with a protruding portion 12 protruding in the thickness direction of the screw hole side thin plate 10. The protruding portion 12 protrudes in the thickness direction of the flat portion 11 from the flat portion 11 formed in a flat plate shape in the screw hole side thin plate 10, and the screw hole side thin plate 10. Is formed in a thin plate-like shape made of a metal material, the protrusion 12 has elasticity. In addition, the protruding portion 12 is formed in a part of a substantially conical shape whose diameter decreases as the thickness direction of the flat surface portion 11 becomes the axial direction and moves away from the flat surface portion 11 in the thickness direction of the flat surface portion 11. ing. Further, the protruding portion 12 has a protruding portion flat portion 16 formed in a plane substantially parallel to the flat portion 11 at an end portion in a direction in which the protruding portion 12 protrudes. Further, the projecting portion 12 has a burring portion 13 on the projecting portion plane portion 16 located at an end portion in a direction away from the plane portion 11. The burring portion 13 protrudes from the protruding portion flat portion 16 in the direction in which the protruding portion 12 protrudes. The protruding portion flat portion 16 and the burring portion 13 are provided as a reinforcing portion that the protruding portion 12 has. Yes. That is, the reinforcing part has a burring part 13, and the protruding part 12 is reinforced by the protruding part flat part 16 and the burring part 13 which are reinforcing parts, and has high rigidity. The burring portion 13 is formed in a substantially cylindrical shape, and is arranged at the tip of the protruding portion 12 such that the axial direction of the cylindrical shape and the axial direction of the substantially conical shape that is the shape of the protruding portion 12 are the same direction. Is formed. Further, since the burring portion 13 is formed in a substantially cylindrical shape, a hole in the thickness direction of the screw hole side thin plate 10 is formed inside the burring portion 13, and this hole is formed by the screwing portion. The lower hole 14 is.

これらの貫通孔側薄板5と螺孔側薄板10とは、締結する際には、螺孔側薄板10を、バーリング部13が貫通孔側薄板5側の反対側に位置する向きにする。さらに、貫通孔側薄板5の貫通孔6と、螺孔側薄板10の下孔14とが、貫通可能な位置関係となるようにし、螺孔側薄板10の平面部11を貫通孔側薄板5に接触させて、貫通孔側薄板5と螺孔側薄板10とを重ねる。螺孔側薄板10には突出部12が形成されているため、このように貫通孔側薄板5と螺孔側薄板10とを重ねることにより、貫通孔6と下孔14とは離間する。つまり、突出部12は、貫通孔6と下孔14と離間させている。   When the through hole side thin plate 5 and the screw hole side thin plate 10 are fastened, the screw hole side thin plate 10 is oriented so that the burring portion 13 is located on the opposite side of the through hole side thin plate 5 side. Furthermore, the through-hole 6 of the through-hole side thin plate 5 and the lower hole 14 of the screw-hole-side thin plate 10 are positioned so as to be able to penetrate, and the flat portion 11 of the screw-hole-side thin plate 10 is connected to the through-hole-side thin plate 5. The through hole side thin plate 5 and the screw hole side thin plate 10 are overlapped with each other. Since the protruding portion 12 is formed in the screw hole side thin plate 10, the through hole 6 and the lower hole 14 are separated by overlapping the through hole side thin plate 5 and the screw hole side thin plate 10 in this manner. That is, the protrusion 12 is separated from the through hole 6 and the lower hole 14.

図2は、実施の形態に係る締結構造で用いるスクリューの外形図である。これらの2枚の薄板1は、締結手段であるスクリュー20によって締結される。このスクリュー20は、セルフタップねじとなっており、略円筒形の形状で形成され、さらに螺旋状に形成されたねじ山23を有するねじ部22と、ねじ部22から離れる方向に凸となる略円盤状の形状で形成されたねじ頭21と、を有している。このうち、ねじ部22には、前記ねじ山23以外に、ねじ山23とねじ山23との間に位置する谷部24が形成されている。   FIG. 2 is an external view of a screw used in the fastening structure according to the embodiment. These two thin plates 1 are fastened by a screw 20 as fastening means. The screw 20 is a self-tapping screw, is formed in a substantially cylindrical shape, and further has a screw portion 22 having a screw thread 23 formed in a spiral shape, and a convex shape in a direction away from the screw portion 22. And a screw head 21 formed in a disk shape. Among these, in addition to the screw thread 23, the screw part 22 is formed with a valley part 24 positioned between the screw thread 23 and the screw thread 23.

また、ねじ山23は、断面形状が略三角形になっており、この形状で谷部24から、ねじ部22の形状である円筒形の径方向外方に突出して螺旋状に形成されている。また、ねじ山23は、ねじ部22におけるねじ頭21寄りの部分には形成されておらず、さらに、ねじ山23のねじ頭21寄りの端部付近では、前記円筒形の径方向における外方への突出量も小さくなっている。このスクリュー20における、ねじ部22のねじ頭21側の端部から、ねじ山23において突出量が小さい部分に隣接する谷部24までの範囲は、不完全ねじ部25となっている。   Further, the screw thread 23 has a substantially triangular cross-sectional shape, and in this shape, the screw thread 23 protrudes outward in the radial direction of the cylindrical shape that is the shape of the screw part 22 and is formed in a spiral shape. Further, the screw thread 23 is not formed in a portion near the screw head 21 in the screw portion 22, and further, in the vicinity of the end portion near the screw head 21 of the screw thread 23, the outer side of the cylindrical shape in the radial direction. The amount of protrusion is also small. In the screw 20, a range from the end portion of the screw portion 22 on the screw head 21 side to the valley portion 24 adjacent to the portion having a small protrusion amount in the screw thread 23 is an incomplete screw portion 25.

図3は、図1の2枚の薄板を締結した状態を示す要部断面図である。この実施の形態に係る締結構造は、以上のごとき構成からなり、以下、その作用について説明する。貫通孔側薄板5と螺孔側薄板10とを締結する場合には、螺孔側薄板10の突出部12が突出している方向が貫通孔側薄板5側の反対側になる向きで、貫通孔側薄板5と螺孔側薄板10とを重ねる。この状態で、スクリュー20のねじ部22を、貫通孔側薄板5における螺孔側薄板10側に位置する面の反対側の面から、当該貫通孔側薄板5に形成された貫通孔6に通す。さらに、このねじ部22を、螺孔側薄板10に形成された下孔14(図1参照)に、ねじ部22の形状である円筒形の周方向に回転させながら通す。その際に、スクリュー20はセルフタップねじとなっているため、ねじ部22に形成されたねじ山23によって、下孔14には溝が形成されながらねじ部22は下孔14を通る。   FIG. 3 is a cross-sectional view of the main part showing a state in which the two thin plates of FIG. 1 are fastened. The fastening structure according to this embodiment is configured as described above, and the operation thereof will be described below. When the through hole side thin plate 5 and the screw hole side thin plate 10 are fastened, the direction in which the protruding portion 12 of the screw hole side thin plate 10 protrudes is opposite to the through hole side thin plate 5 side, and the through hole The side thin plate 5 and the screw hole side thin plate 10 are overlapped. In this state, the screw portion 22 of the screw 20 is passed through the through hole 6 formed in the through hole side thin plate 5 from the surface of the through hole side thin plate 5 opposite to the surface located on the screw hole side thin plate 10 side. . Further, the screw portion 22 is passed through the pilot hole 14 (see FIG. 1) formed in the screw hole side thin plate 10 while being rotated in the circumferential direction of the cylindrical shape that is the shape of the screw portion 22. At this time, since the screw 20 is a self-tapping screw, a groove is formed in the lower hole 14 by the screw thread 23 formed in the screw portion 22, and the screw portion 22 passes through the lower hole 14.

即ち、スクリュー20のねじ部22を下孔14にねじ込むことにより、下孔14にはねじ部22のねじ山23によって当該ねじ山23とほぼ同形状の螺線状の溝が形成され、下孔14は螺孔15となって形成される。これにより、スクリュー20のねじ部22と、スクリュー20をねじ込むことによって螺孔側薄板10に形成された螺孔15とは螺合する。つまり、スクリュー20をねじ込むことによって形成された螺孔15も螺合部となっている。   That is, by screwing the screw portion 22 of the screw 20 into the lower hole 14, a spiral groove having substantially the same shape as the screw thread 23 is formed in the lower hole 14 by the screw thread 23 of the screw portion 22. 14 is formed as a screw hole 15. Thereby, the screw part 22 of the screw 20 and the screw hole 15 formed in the screw hole side thin plate 10 by screwing the screw 20 are screwed together. That is, the screw hole 15 formed by screwing the screw 20 is also a screwing portion.

このように、スクリュー20を螺孔側薄板10に形成された螺孔15にねじ込み、ねじ頭21が貫通孔側薄板5における螺孔側薄板10側の面と反対側の面に当接することにより、貫通孔側薄板5はねじ頭21によって螺孔側薄板10の方向に押さえ付けられる。また、スクリュー20のねじ部22を螺孔15にねじ込むことにより、この螺孔15、つまり、螺孔側薄板10には、貫通孔側薄板5の方向への力が作用する。これらにより、貫通孔側薄板5と螺孔側薄板10とには、互いに他方に押し付けられる力が作用する。   In this way, the screw 20 is screwed into the screw hole 15 formed in the screw hole side thin plate 10, and the screw head 21 comes into contact with the surface of the through hole side thin plate 5 opposite to the surface on the screw hole side thin plate 10 side. The through hole side thin plate 5 is pressed by the screw head 21 toward the screw hole side thin plate 10. Further, by screwing the screw portion 22 of the screw 20 into the screw hole 15, a force in the direction of the through hole side thin plate 5 acts on the screw hole 15, that is, the screw hole side thin plate 10. As a result, forces that are pressed against each other act on the through hole side thin plate 5 and the screw hole side thin plate 10.

図4は、図3の突出部が変形した状態を示す図である。また、螺孔15は突出部12によって貫通孔側薄板5から離間しており、貫通孔側薄板5及び螺孔側薄板10は、共に金属材料により形成されていることにより、弾力性を有している。この弾力性は、螺孔側薄板10に形成された突出部12も有しており、また、スクリュー20を螺孔15にねじ込んだ場合には、螺孔15には貫通孔側薄板5の方向への力が作用するため、突出部12は弾性変形をし、螺孔15が貫通孔側薄板5の方向に若干近付く方向に撓む。その際に、突出部12は突出部平面部16とバーリング部13とを有しているため、突出部12は突出部平面部16とバーリング部13とによって補強されている。これにより、突出部12が弾性変形をして撓んだ場合でも、突出部12は撓み過ぎることが抑制され、貫通孔6と螺孔15とが接触しない程度に撓む。   FIG. 4 is a diagram illustrating a state in which the protruding portion of FIG. 3 is deformed. Further, the screw hole 15 is separated from the through hole side thin plate 5 by the projecting portion 12, and the through hole side thin plate 5 and the screw hole side thin plate 10 are both made of a metal material, and thus have elasticity. ing. This elasticity also has a protruding portion 12 formed on the screw hole side thin plate 10, and when the screw 20 is screwed into the screw hole 15, the screw hole 15 has a direction of the through hole side thin plate 5. Therefore, the protrusion 12 is elastically deformed, and the screw hole 15 is bent in a direction slightly approaching the direction of the through-hole side thin plate 5. At this time, since the protruding portion 12 includes the protruding portion flat portion 16 and the burring portion 13, the protruding portion 12 is reinforced by the protruding portion flat portion 16 and the burring portion 13. Thereby, even when the protruding portion 12 is bent due to elastic deformation, the protruding portion 12 is suppressed from being bent excessively, and is bent to the extent that the through hole 6 and the screw hole 15 do not contact each other.

また、突出部12には、弾力性による弾性力によって、撓んだ形状が元の形状に戻ろうとする力が作用するが、螺孔15はスクリュー20と螺合しているため、移動し難くなっている。このため、この突出部12の弾性力は、螺孔15を元の位置に移動させる代わりに、平面部11を貫通孔側薄板5に押し付ける力となって作用する。従って、スクリュー20のねじ部22を貫通孔側薄板5に形成された貫通孔6に通し、さらに、螺孔側薄板10の下孔14(図1参照)、或いは螺孔15にねじ込んでねじ部22と螺孔15とを螺合させることにより、貫通孔側薄板5と螺孔側薄板10とは、締結する。   In addition, a force that causes the bent shape to return to the original shape is applied to the protruding portion 12 due to the elastic force due to elasticity, but the screw hole 15 is screwed with the screw 20 and thus is difficult to move. It has become. For this reason, the elastic force of the projecting portion 12 acts as a force for pressing the flat portion 11 against the through-hole-side thin plate 5 instead of moving the screw hole 15 to the original position. Therefore, the screw portion 22 of the screw 20 is passed through the through hole 6 formed in the through hole side thin plate 5 and further screwed into the lower hole 14 (see FIG. 1) or the screw hole 15 of the screw hole side thin plate 10. The through hole side thin plate 5 and the screw hole side thin plate 10 are fastened by screwing the screw 22 and the screw hole 15 together.

また、このように、スクリュー20によって貫通孔側薄板5と螺孔側薄板10とが締結された状態においても、螺孔側薄板10に形成された突出部12が貫通孔側薄板5の反対方向に突出していることにより、貫通孔6と螺孔15とは離間している。このため、スクリュー20の不完全ねじ部25の大部分は貫通孔6の内側、及び螺孔15と貫通孔6との間に位置し、螺孔15内に位置するねじ部22の大部分は、完全な形状となっているねじ山23が形成されたねじ部22となっている。   In addition, even when the through hole side thin plate 5 and the screw hole side thin plate 10 are fastened by the screw 20 as described above, the protruding portion 12 formed on the screw hole side thin plate 10 is opposite to the through hole side thin plate 5. The through hole 6 and the screw hole 15 are separated from each other. For this reason, most of the incomplete screw portion 25 of the screw 20 is located inside the through hole 6 and between the screw hole 15 and the through hole 6, and most of the screw portion 22 located in the screw hole 15 is The screw portion 22 is formed with a screw thread 23 having a complete shape.

以上の締結構造は、2枚の薄板1のうち、一方の薄板1である貫通孔側薄板5には貫通孔6を形成し、他方の薄板1である螺孔側薄板10には螺合部であり、スクリュー20をねじ込むことにより螺孔15となる下孔14を形成している。また、螺孔側薄板10には、貫通孔6と下孔14とを離間させる突出部12が形成されているため、下孔14にスクリュー20がねじ込まれ、下孔14が螺孔15になった場合でも、貫通孔6と螺孔15とは離間している。これにより、スクリュー20を貫通孔6側から螺孔15に対して螺合させた場合、スクリュー20の不完全ねじ部25を、貫通孔6内、及び貫通孔6と螺孔15との間に位置させ、スクリュー20のねじ部22と螺孔15とを、より確実に螺合することができる。   In the above fastening structure, of the two thin plates 1, the through hole 6 is formed in the through hole side thin plate 5 which is one thin plate 1, and the screw hole side thin plate 10 which is the other thin plate 1 is screwed. The lower hole 14 to be the screw hole 15 is formed by screwing the screw 20. Further, since the protruding portion 12 that separates the through hole 6 and the lower hole 14 is formed in the screw hole side thin plate 10, the screw 20 is screwed into the lower hole 14, and the lower hole 14 becomes the screw hole 15. Even in this case, the through hole 6 and the screw hole 15 are separated from each other. Accordingly, when the screw 20 is screwed into the screw hole 15 from the through hole 6 side, the incomplete screw portion 25 of the screw 20 is inserted into the through hole 6 and between the through hole 6 and the screw hole 15. The screw portion 22 and the screw hole 15 of the screw 20 can be screwed more reliably.

また、突出部12は弾力性を有しているため、この突出部12が有するバーリング部13に形成される螺孔15にスクリュー20をねじ込むことにより、突出部12は弾性変形をする。スクリュー20を螺孔15にねじ込んだ際には、このように弾性変形をする突出部12の弾性力によって螺孔側薄板10の平面部11は貫通孔側薄板5に押し付けられる。その際に、突出部12は突出部平面部16とバーリング部13とによって補強されているので、大きく弾性変形して貫通孔6と螺孔15とが接触することが抑制され、より確実にスクリュー20の不完全ねじ部25を、貫通孔6内、及び貫通孔6と螺孔15との間に位置させることができる。さらに、突出部12は螺孔側薄板10にのみ設けられており、例えば、突出部12と、貫通孔側薄板5に形成された他の部位を嵌合する場合のように、突出部12を高い精度で製造する必要がないので、容易に製造することができる。これらの結果、締結部材である薄板1同士を、容易に、且つ、より確実に締結することができる。   Further, since the protrusion 12 has elasticity, the protrusion 12 is elastically deformed by screwing the screw 20 into the screw hole 15 formed in the burring portion 13 of the protrusion 12. When the screw 20 is screwed into the screw hole 15, the flat portion 11 of the screw hole side thin plate 10 is pressed against the through hole side thin plate 5 by the elastic force of the protruding portion 12 that elastically deforms in this way. At this time, since the protrusion 12 is reinforced by the protrusion flat portion 16 and the burring portion 13, the elastic deformation is greatly suppressed and the contact between the through hole 6 and the screw hole 15 is suppressed, and the screw is more reliably secured. The 20 incomplete thread portions 25 can be positioned in the through hole 6 and between the through hole 6 and the screw hole 15. Further, the protruding portion 12 is provided only on the screw hole side thin plate 10. For example, the protruding portion 12 may be connected to another portion formed on the through hole side thin plate 5. Since it is not necessary to manufacture with high precision, it can be manufactured easily. As a result, the thin plates 1 that are fastening members can be easily and more reliably fastened.

また、突出部12を螺孔側薄板10に形成し、螺孔15が貫通孔側薄板5から離れる方向に突出させているので、貫通孔側薄板5は平坦な形状になっている。このため、貫通孔側薄板5が、当該薄板1を有する機器の外観を形成する部材である場合でも、外観へ影響を抑制できる。この結果、美観を損ねることなく、薄板1同士を、より確実に締結することができる。   Moreover, since the protrusion part 12 is formed in the screw hole side thin plate 10, and the screw hole 15 is protruded in the direction away from the through hole side thin plate 5, the through hole side thin plate 5 has a flat shape. For this reason, even when the through-hole side thin plate 5 is a member which forms the external appearance of the apparatus which has the said thin plate 1, an influence on an external appearance can be suppressed. As a result, the thin plates 1 can be more securely fastened without impairing the beauty.

また、スクリュー20を、貫通孔側薄板5に形成された貫通孔6に通し、貫通孔6に通したスクリュー20を、螺孔側薄板10の螺孔15に螺合させることにより、貫通孔側薄板5と螺孔側薄板10とを締結している。これにより、貫通孔側薄板5と螺孔側薄板10とに対して、双方が近づく方向の付勢力を与えることができると共に、スクリュー20の不完全ねじ部25を、貫通孔6内、及び貫通孔6と螺孔15との間に位置させることができる。従って、スクリュー20のねじ部22と螺孔15とを、より確実に螺合することができる。この結果、薄板1同士を、より確実に締結することができる。   Further, by passing the screw 20 through the through hole 6 formed in the through hole side thin plate 5 and screwing the screw 20 passed through the through hole 6 into the screw hole 15 of the screw hole side thin plate 10, the through hole side The thin plate 5 and the screw hole side thin plate 10 are fastened together. Thereby, while being able to give the urging | biasing force of the direction which both approach with respect to the through-hole side thin plate 5 and the screw-hole side thin plate 10, the incomplete thread part 25 of the screw 20 is penetrated in the through-hole 6 and through. It can be located between the hole 6 and the screw hole 15. Therefore, the screw part 22 of the screw 20 and the screw hole 15 can be screwed together more reliably. As a result, the thin plates 1 can be fastened more reliably.

また、螺孔側薄板10に突出部12を形成し、螺孔15が貫通孔6から離間した状態で螺孔側薄板10と貫通孔側薄板5とを締結しているので、スクリュー20を螺孔15にねじ込んだ際に、突出部12の弾性力によって、平面部11を貫通孔側薄板5の方向に押し付けることができる。また、突出部12の弾性力は、螺孔15が貫通孔側薄板5から離れる方向に作用し、この力はスクリュー20に伝えられるため、スクリュー20のねじ部22と螺孔15との接触部分や、スクリュー20のねじ頭21と貫通孔側薄板5との接触部分の摩擦力は、大きくなる。このため、スクリュー20は、ねじ部22の形状である略円筒形の周方向に回転し難くなるため、スクリュー20は緩み難くなり、スクリュー20を、螺孔15に対してより確実に螺合することができる。この結果、薄板1同士を、より確実に締結することができる。   Further, since the protruding portion 12 is formed on the screw hole side thin plate 10 and the screw hole side thin plate 10 and the through hole side thin plate 5 are fastened with the screw hole 15 being separated from the through hole 6, the screw 20 is screwed. When screwed into the hole 15, the flat surface portion 11 can be pressed in the direction of the through-hole side thin plate 5 by the elastic force of the protruding portion 12. Further, the elastic force of the projecting portion 12 acts in a direction in which the screw hole 15 moves away from the through-hole-side thin plate 5, and this force is transmitted to the screw 20, so the contact portion between the screw portion 22 of the screw 20 and the screw hole 15. Or the frictional force of the contact part of the screw head 21 of the screw 20 and the through-hole side thin plate 5 becomes large. For this reason, the screw 20 is difficult to rotate in the circumferential direction of the substantially cylindrical shape that is the shape of the screw portion 22, and thus the screw 20 is difficult to loosen, and the screw 20 is more reliably screwed into the screw hole 15. be able to. As a result, the thin plates 1 can be fastened more reliably.

図5は、実施の形態に係る締結構造の変形例を示す要部断面図である。なお、上述した締結構造では、突出部12は螺孔側薄板10に形成しているが、突出部は、例えば図5に示すように、貫通孔側薄板30に形成してもよい。つまり、貫通孔側薄板30のうち、平坦な板状の形状で形成されている平面部32から、当該平面部32の厚さ方向に、上述した螺孔側薄板10の突出部12と同様な形状で弾力性を有する突出部33を突出させる。この突出部33は、当該突出部33が突出している方向における端部に、前記平面部32とほぼ平行な平面で形成された突出部平面部34を有している。貫通孔31は、この突出部33の突出部平面部34に形成されている。また、この突出部平面部34は、突出部33を補強する補強部として設けられており、その形状は、貫通孔側薄板30と螺孔側薄板35とを締結するスクリュー20のねじ頭21の径とほぼ同一の径となる、略円形の板状の形状となっている。これにより、突出部33は、大きい面積で形成される突出部平面部34が設けられることになるので、剛性が確保され、当該突出部33は補強される。また、このように貫通孔側薄板30に突出部33が形成される場合には螺孔側薄板35には突出部は形成せず、平面部36から直接バーリング部37を突出させ、このバーリング部37の内側に下孔38を形成する。   FIG. 5 is a cross-sectional view of a main part showing a modification of the fastening structure according to the embodiment. In the fastening structure described above, the projecting portion 12 is formed on the screw hole side thin plate 10, but the projecting portion may be formed on the through hole side thin plate 30 as shown in FIG. That is, in the through hole side thin plate 30, the same as the protrusion 12 of the screw hole side thin plate 10 described above from the flat portion 32 formed in a flat plate shape in the thickness direction of the flat portion 32. The protruding portion 33 having elasticity in the shape is protruded. The projecting portion 33 has a projecting portion plane portion 34 formed on a plane substantially parallel to the planar portion 32 at an end portion in the direction in which the projecting portion 33 projects. The through hole 31 is formed in the protruding portion flat portion 34 of the protruding portion 33. In addition, the projecting portion flat portion 34 is provided as a reinforcing portion that reinforces the projecting portion 33, and the shape thereof is that of the screw head 21 of the screw 20 that fastens the through hole side thin plate 30 and the screw hole side thin plate 35. It has a substantially circular plate-like shape having a diameter substantially the same as the diameter. Thereby, since the protrusion part 33 is provided with the protrusion part plane part 34 formed with a large area, rigidity is ensured and the protrusion part 33 is reinforced. Further, when the protruding portion 33 is formed on the through hole side thin plate 30 in this way, the protruding portion is not formed on the screw hole side thin plate 35, and the burring portion 37 is directly projected from the flat portion 36. A pilot hole 38 is formed inside 37.

これらの貫通孔側薄板30と螺孔側薄板35とを締結する際には、貫通孔側薄板30を、突出部33が螺孔側薄板35側の反対側に位置する向きにし、螺孔側薄板35を、バーリング部37が貫通孔側薄板30側の反対側に位置する向きにする。この向きで、双方の平面部32、36同士を接触させて、貫通孔側薄板30と螺孔側薄板35とを重ねる。これにより、貫通孔31と下孔38とは離間する。つまり、貫通孔側薄板30に形成された突出部33は、当該貫通孔側薄板30に形成された貫通孔31が螺孔側薄板35から離れる方向に突出しており、貫通孔31と下孔38とを離間させている。   When the through-hole side thin plate 30 and the screw hole-side thin plate 35 are fastened, the through-hole side thin plate 30 is oriented so that the protruding portion 33 is located on the opposite side of the screw hole-side thin plate 35 side. The thin plate 35 is oriented so that the burring portion 37 is located on the opposite side of the through hole side thin plate 30 side. In this orientation, both the flat portions 32 and 36 are brought into contact with each other, and the through hole side thin plate 30 and the screw hole side thin plate 35 are overlapped. Thereby, the through hole 31 and the lower hole 38 are separated from each other. That is, the protruding portion 33 formed in the through-hole side thin plate 30 protrudes in a direction in which the through-hole 31 formed in the through-hole side thin plate 30 is separated from the screw-hole-side thin plate 35, and the through-hole 31 and the lower hole 38. Are separated from each other.

さらに、この状態で、スクリュー20のねじ部22を、貫通孔側薄板30の貫通孔31に通した後、螺孔側薄板35の下孔38にねじ部22をねじ込むことにより、下孔38にねじ部22のねじ山23とほぼ同形状の螺旋状の溝を形成する。つまり、下孔38に螺旋上の溝が形成されることにより、下孔38は螺孔39になる。これにより、スクリュー20のねじ部22と、螺孔側薄板35の螺孔39と螺合させることができ、このスクリュー20によって、貫通孔側薄板30と螺孔側薄板35とを締結することができる。   Further, in this state, the screw portion 22 of the screw 20 is passed through the through-hole 31 of the through-hole side thin plate 30, and then the screw portion 22 is screwed into the lower hole 38 of the screw-hole side thin plate 35. A spiral groove having substantially the same shape as the thread 23 of the screw portion 22 is formed. That is, the lower hole 38 becomes a screw hole 39 by forming a spiral groove in the lower hole 38. Accordingly, the screw portion 22 of the screw 20 and the screw hole 39 of the screw hole side thin plate 35 can be screwed together, and the through hole side thin plate 30 and the screw hole side thin plate 35 can be fastened by the screw 20. it can.

図6は、図5の突出部が変形した状態を示す図である。また、突出部33に形成された貫通孔31にスクリュー20のねじ部22を通し、ねじ部22を螺孔側薄板35の螺孔39にねじ込んだ際には、スクリュー20のねじ頭21は突出部33の突出部平面部34に接触する。さらに、この状態でスクリュー20をねじ込むと、スクリュー20のねじ頭21は突出部33に対し、当該突出部33を螺孔側薄板35の方向に押し付ける力を与える。この力を受けた突出部33は、当該突出部33が有する弾力性によって弾性変形をし、突出部33に形成された貫通孔31が螺孔側薄板35の方向に若干近付く方向に撓む。その際に、突出部33は突出部平面部34を有しているため、突出部33は突出部平面部34によって補強されている。これにより、突出部33が弾性変形をして撓んだ場合でも、突出部33は撓み過ぎることが抑制され、貫通孔31と螺孔39とが接触しない程度に撓む。また、弾性変形をした突出部33には、弾力性による弾性力によって、撓んだ形状が元に戻ろうとする力が作用するが、スクリュー20が螺孔39と螺合しているため、元の形状には戻り難くなっている。このため、この突出部33の弾性力は、貫通孔側薄板30の平面部32を螺孔側薄板35に押し付ける力となって作用する。   FIG. 6 is a diagram illustrating a state in which the protruding portion of FIG. 5 is deformed. Further, when the screw portion 22 of the screw 20 is passed through the through hole 31 formed in the protruding portion 33 and the screw portion 22 is screwed into the screw hole 39 of the screw hole side thin plate 35, the screw head 21 of the screw 20 protrudes. It contacts the protruding portion flat portion 34 of the portion 33. Further, when the screw 20 is screwed in this state, the screw head 21 of the screw 20 applies a force to the projecting portion 33 to press the projecting portion 33 toward the screw hole side thin plate 35. The projecting portion 33 that has received this force is elastically deformed by the elasticity of the projecting portion 33, and the through hole 31 formed in the projecting portion 33 bends in a direction slightly approaching the direction of the screw hole side thin plate 35. At this time, since the protruding portion 33 has the protruding portion flat portion 34, the protruding portion 33 is reinforced by the protruding portion flat portion 34. Thereby, even when the protruding portion 33 is bent due to elastic deformation, the protruding portion 33 is suppressed from being bent excessively, and is bent to the extent that the through hole 31 and the screw hole 39 do not contact each other. Further, the elastically deformed projecting portion 33 is subjected to a force to return the bent shape to the original due to the elastic force due to elasticity, but the screw 20 is screwed into the screw hole 39, so It is difficult to return to the shape. For this reason, the elastic force of the projecting portion 33 acts as a force for pressing the flat portion 32 of the through hole side thin plate 30 against the screw hole side thin plate 35.

このように、突出部33を貫通孔側薄板30に形成した場合でも、貫通孔側薄板30に形成される貫通孔31と、螺孔側薄板35に形成される下孔38、或いは螺孔39とを離間させることができる。従って、スクリュー20を貫通孔31側から螺孔39に対して螺合させた場合、スクリュー20の不完全ねじ部25を、貫通孔31内、及び貫通孔31と螺孔39との間に位置させ、スクリュー20のねじ部22と螺孔39とを、より確実に螺合することができる。また、貫通孔側薄板30に形成する突出部33が弾力性を有することにより、スクリュー20を螺孔39にねじ込んだ際の突出部33の弾性力によって、貫通孔側薄板30の平面部32を螺孔側薄板35に押し付けることができ、また、スクリュー20の緩みを抑制できる。また、その際に、突出部33は突出部平面部34によって補強されているので、大きく弾性変形して貫通孔31と螺孔39とが接触することが抑制され、より確実にスクリュー20の不完全ねじ部25を、貫通孔31内、及び貫通孔31と螺孔39との間に位置させることができる。さらに、突出部33は貫通孔側薄板30にのみ設けられており、例えば、突出部33と、螺孔側薄板35に形成された他の部位を嵌合する場合のように、突出部33を高い精度で製造する必要ないので、容易に製造することができる。これらの結果、薄板1同士を、容易に、且つ、より確実に締結することができる。   Thus, even when the protrusion 33 is formed in the through-hole side thin plate 30, the through-hole 31 formed in the through-hole side thin plate 30 and the lower hole 38 or the screw hole 39 formed in the screw-hole side thin plate 35. Can be separated from each other. Therefore, when the screw 20 is screwed into the screw hole 39 from the through hole 31 side, the incomplete screw portion 25 of the screw 20 is positioned in the through hole 31 and between the through hole 31 and the screw hole 39. Thus, the screw portion 22 of the screw 20 and the screw hole 39 can be more reliably screwed together. Further, since the protruding portion 33 formed on the through hole side thin plate 30 has elasticity, the flat portion 32 of the through hole side thin plate 30 is formed by the elastic force of the protruding portion 33 when the screw 20 is screwed into the screw hole 39. It can be pressed against the screw hole side thin plate 35, and loosening of the screw 20 can be suppressed. At this time, since the protrusion 33 is reinforced by the protrusion flat portion 34, it is possible to prevent elastic deformation of the protrusion 33 and contact between the through hole 31 and the screw hole 39, and to prevent the screw 20 from being more reliably fixed. The complete screw portion 25 can be positioned in the through hole 31 and between the through hole 31 and the screw hole 39. Further, the protruding portion 33 is provided only on the through-hole side thin plate 30. For example, the protruding portion 33 is formed by fitting the protruding portion 33 with another portion formed on the screw hole-side thin plate 35. Since it is not necessary to manufacture with high precision, it can be manufactured easily. As a result, the thin plates 1 can be easily and more securely fastened.

図7は、実施の形態に係る締結構造の変形例を示す要部断面図である。また、突出部を螺孔側薄板に形成する場合には、突出部の突出の方向は、螺孔を突出させる方向以外の方向でもよい。例えば、図7に示すように、螺孔側薄板40は、平面部41に対し、突出部42とバーリング部43とを互いに反対方向になる向きに突出させてもよい。つまり、バーリング部43は、平面部41の一方の面から突出させ、突出部42は、バーリング部43の内側に形成された下孔44の近傍において、バーリング部43が形成された面と反対側の面から、バーリング部43が突出している方向と反対方向に突出させてもよい。詳しくは、突出部42は、下孔44の近傍で下孔44の周囲に設けてもよい。ここで、この突出部42は、螺孔側薄板40と連続して螺孔側薄板40と同じ材料によって形成されており、螺孔側薄板40は、厚さが薄い金属材料によって形成されている。このため、螺孔側薄板40及び突出部42は、共に弾力性を有している。また、この突出部42は、下孔44の径方向における外側方向と内側方向との双方に、当該突出部42が突出している方向に向けて形成された突出部壁部46を有している。突出部42は、この双方の突出部壁部46によって突出方向の剛性が高くなっており、突出部壁部46によって補強されている。即ち、突出部壁部46は補強部として形成されている。なお、この突出部42は、バーリング部43に形成された下孔44の周囲の全周に連続して形成してもよく、複数の突出部42を下孔44の周囲において互いに離間させて形成してもよい。   FIG. 7 is a cross-sectional view of an essential part showing a modification of the fastening structure according to the embodiment. Further, when the protruding portion is formed on the screw hole side thin plate, the protruding direction of the protruding portion may be a direction other than the direction in which the screw hole is protruded. For example, as shown in FIG. 7, the screw hole side thin plate 40 may protrude the protruding portion 42 and the burring portion 43 in directions opposite to each other with respect to the flat portion 41. That is, the burring portion 43 protrudes from one surface of the flat portion 41, and the protruding portion 42 is in the vicinity of the lower hole 44 formed inside the burring portion 43, opposite to the surface on which the burring portion 43 is formed. You may make it protrude from the surface in the direction opposite to the direction from which the burring part 43 protrudes. Specifically, the protrusion 42 may be provided around the lower hole 44 in the vicinity of the lower hole 44. Here, the projecting portion 42 is formed of the same material as that of the screw hole side thin plate 40 continuously with the screw hole side thin plate 40, and the screw hole side thin plate 40 is formed of a metal material having a small thickness. . For this reason, both the screw hole side thin plate 40 and the protrusion part 42 have elasticity. Further, the protruding portion 42 has protruding portion wall portions 46 formed in both the outer direction and the inner direction in the radial direction of the lower hole 44 toward the direction in which the protruding portion 42 protrudes. . The protruding portion 42 has a high rigidity in the protruding direction by both protruding portion wall portions 46, and is reinforced by the protruding portion wall portion 46. That is, the protruding portion wall portion 46 is formed as a reinforcing portion. The protrusion 42 may be formed continuously around the entire periphery of the lower hole 44 formed in the burring portion 43, and the plurality of protrusions 42 are formed apart from each other around the lower hole 44. May be.

このように形成された螺孔側薄板40と貫通孔側薄板5とを締結する際には、螺孔側薄板40を、突出部42が突出している側の面が貫通孔側薄板5側に位置するような向きにして、螺孔側薄板40と貫通孔側薄板5とを重ねる。この場合、螺孔側薄板40の突出部42は貫通孔側薄板5の方向に突出しているため、螺孔側薄板40の平面部41は貫通孔側薄板5に接触せず、螺孔側薄板40は、突出部42のみが貫通孔側薄板5に接触する。このため、螺孔側薄板40に形成される下孔44や平面部41は、貫通孔側薄板5に対して離間する。また、このように突出部42は、下孔44を貫通孔側薄板5から離間させる方向と反対方向に突出している。   When the thus formed screw hole side thin plate 40 and the through hole side thin plate 5 are fastened, the screw hole side thin plate 40 is placed so that the surface on which the protruding portion 42 protrudes faces the through hole side thin plate 5. The screw hole side thin plate 40 and the through hole side thin plate 5 are overlapped in such a direction as to be positioned. In this case, since the protruding portion 42 of the screw hole side thin plate 40 protrudes in the direction of the through hole side thin plate 5, the flat portion 41 of the screw hole side thin plate 40 does not contact the through hole side thin plate 5, and the screw hole side thin plate. As for 40, only the protrusion part 42 contacts the through-hole side thin plate 5. FIG. For this reason, the lower hole 44 and the flat part 41 formed in the screw hole side thin plate 40 are separated from the through hole side thin plate 5. Further, in this manner, the protruding portion 42 protrudes in the direction opposite to the direction in which the lower hole 44 is separated from the through-hole side thin plate 5.

貫通孔側薄板5と螺孔側薄板40とは、このように形成されるため、スクリュー20で貫通孔側薄板5と螺孔側薄板40とを締結した場合に、貫通孔側薄板5に形成される貫通孔6と、螺孔側薄板40に形成される下孔44、或いは螺孔45とを、離間させることができる。つまり、螺孔側薄板40に形成される突出部42を、螺孔45が貫通孔側薄板5に対して離間する方向と反対方向に突出させた場合でも、貫通孔6と螺孔45を離間させることができる。従って、スクリュー20の不完全ねじ部25を、貫通孔6内、及び貫通孔6と螺孔45との間に位置させることができ、スクリュー20のねじ部22と螺孔45とを、より確実に螺合することができる。また、螺孔側薄板40に形成する突出部42が弾力性を有することにより、スクリュー20を螺孔45にねじ込んだ際の突出部42の弾性力によって、当該突出部42は貫通孔側薄板5に押し付けられ、また、スクリュー20の緩みを抑制できる。また、その際に、突出部42は突出部壁部46によって補強されているので、大きく弾性変形して貫通孔6と螺孔45とが接触することが抑制され、より確実にスクリュー20の不完全ねじ部25を、貫通孔6内、及び貫通孔6と螺孔45との間に位置させることができる。さらに、突出部42は螺孔側薄板40にのみ設けられ、貫通孔側薄板5に接触するのみなので、突出部42を高い精度で製造する必要がなく、容易に製造することができる。この結果、薄板1同士を、容易に、且つ、より確実に締結することができる。   Since the through hole side thin plate 5 and the screw hole side thin plate 40 are formed in this way, when the through hole side thin plate 5 and the screw hole side thin plate 40 are fastened by the screw 20, they are formed in the through hole side thin plate 5. The through hole 6 and the lower hole 44 or the screw hole 45 formed in the screw hole side thin plate 40 can be separated from each other. That is, even when the protruding portion 42 formed in the screw hole side thin plate 40 is protruded in the direction opposite to the direction in which the screw hole 45 is separated from the through hole side thin plate 5, the through hole 6 and the screw hole 45 are separated from each other. Can be made. Accordingly, the incomplete screw portion 25 of the screw 20 can be positioned in the through hole 6 and between the through hole 6 and the screw hole 45, and the screw portion 22 and the screw hole 45 of the screw 20 can be more reliably connected. Can be screwed together. Further, since the protruding portion 42 formed on the screw hole side thin plate 40 has elasticity, the protruding portion 42 is formed through the through hole side thin plate 5 by the elastic force of the protruding portion 42 when the screw 20 is screwed into the screw hole 45. In addition, the looseness of the screw 20 can be suppressed. Further, at this time, since the protruding portion 42 is reinforced by the protruding portion wall portion 46, the elastic deformation of the protruding portion 42 and the contact between the through hole 6 and the screw hole 45 is suppressed, and the screw 20 is more reliably fixed. The complete screw portion 25 can be positioned in the through hole 6 and between the through hole 6 and the screw hole 45. Furthermore, since the protrusion 42 is provided only on the screw hole side thin plate 40 and only contacts the through hole side thin plate 5, the protrusion 42 does not need to be manufactured with high accuracy and can be easily manufactured. As a result, the thin plates 1 can be easily and more securely fastened.

図8は、実施の形態に係る締結構造の変形例を示す要部断面図である。図9は、図8のA−A矢視図である。また、上述した締結方法は、下孔や螺孔などの螺合部と貫通孔とを離間させているが、螺合部と貫通孔とを離間させずに、2枚の薄板を締結してもよい。例えば、図8、9に示すように、貫通孔側薄板50に突出部53を形成し、貫通孔51は、貫通孔側薄板50の厚さ方向において当該貫通孔側薄板50の平面部52と同じ位置に形成してもよい。つまり、貫通孔側薄板50は、平面部52から突出部53を突出させることに伴って貫通孔51を平面部52から突出させずに、貫通孔51の近傍において、突出部53のみを平面部52から突出させてもよい。このように設けられる突出部53は、貫通孔側薄板50と連続して貫通孔側薄板50と同じ材料によって形成されており、貫通孔側薄板50は、厚さが薄い金属材料によって形成されている。また、突出部53は、貫通孔51の周囲の全周に連続して形成されており、さらに、この突出部53は、貫通孔51の径方向における外側方向と内側方向との双方に、当該突出部53が突出している方向に向けて形成された突出部壁部54を有している。突出部53は、この双方の突出部壁部54によって突出方向の剛性が高くなっており、突出部壁部54によって補強されている。即ち、突出部壁部54は補強部として形成されている。これに対し、螺孔側薄板35には突出部を形成せず、平面部36からバーリング部37のみを突出させ、バーリング部37の内側には下孔38を形成する。   FIG. 8 is a cross-sectional view of a main part showing a modified example of the fastening structure according to the embodiment. FIG. 9 is an AA arrow view of FIG. In the above-described fastening method, the threaded portion such as the lower hole and the screw hole and the through hole are separated from each other, but the two thin plates are fastened without separating the threaded portion and the through hole. Also good. For example, as shown in FIGS. 8 and 9, a protruding portion 53 is formed in the through-hole side thin plate 50, and the through-hole 51 is connected to the flat portion 52 of the through-hole side thin plate 50 in the thickness direction of the through-hole side thin plate 50. You may form in the same position. That is, the through-hole-side thin plate 50 does not project the through-hole 51 from the planar portion 52 in association with the projecting portion 53 projecting from the planar portion 52, but only the projecting portion 53 in the vicinity of the through-hole 51. You may make it protrude from 52. The protrusion 53 provided in this way is formed of the same material as the through-hole side thin plate 50 continuously with the through-hole side thin plate 50, and the through-hole side thin plate 50 is formed of a thin metal material. Yes. Further, the protruding portion 53 is formed continuously around the entire periphery of the through hole 51, and the protruding portion 53 is provided in both the outer side and the inner side in the radial direction of the through hole 51. It has the protrusion part wall part 54 formed toward the direction where the protrusion part 53 protrudes. The protrusion 53 has a high rigidity in the protrusion direction due to both of the protrusion walls 54 and is reinforced by the protrusion wall 54. That is, the protruding portion wall portion 54 is formed as a reinforcing portion. On the other hand, the protruding portion is not formed on the screw hole side thin plate 35, but only the burring portion 37 is protruded from the flat portion 36, and the lower hole 38 is formed inside the burring portion 37.

このように形成された貫通孔側薄板50と螺孔側薄板35とを締結する際に、貫通孔側薄板50は、突出部53が突出している側の面が螺孔側薄板35側の反対側に位置する向きにし、螺孔側薄板35は、バーリング部37が突出している側の面が貫通孔側薄板50側の反対側に位置する向きにして、貫通孔側薄板50と螺孔側薄板35とを重ねる。つまり、この状態では突出部53は、螺孔側薄板35が位置する方向と反対方向に突出しており、バーリング部37は、貫通孔側薄板50が位置する方向と反対方向に突出している。これにより、貫通孔側薄板50の平面部52と螺孔側薄板35の平面部36とは接触し、これに伴い、貫通孔側薄板50の貫通孔51と螺孔側薄板35の下孔38とは、接近する。   When the through hole side thin plate 50 and the screw hole side thin plate 35 thus formed are fastened, the through hole side thin plate 50 has a surface on the side where the protruding portion 53 protrudes opposite to the screw hole side thin plate 35 side. The screw hole side thin plate 35 is oriented so that the surface on the side from which the burring portion 37 protrudes is located on the opposite side of the through hole side thin plate 50 side and the through hole side thin plate 50 and the screw hole side. The thin plate 35 is overlaid. That is, in this state, the protruding portion 53 protrudes in the direction opposite to the direction in which the screw hole side thin plate 35 is located, and the burring portion 37 protrudes in the direction opposite to the direction in which the through hole side thin plate 50 is located. As a result, the flat portion 52 of the through hole side thin plate 50 and the flat portion 36 of the screw hole side thin plate 35 come into contact with each other, and accordingly, the through hole 51 of the through hole side thin plate 50 and the lower hole 38 of the screw hole side thin plate 35. And approach.

スクリュー20は、このように螺孔側薄板35に重ねられた貫通孔側薄板50の突出部53側の面からねじ部22を貫通孔51に通し、さらに、ねじ部22を螺孔側薄板35に形成された下孔38にねじ込みながら下孔38を螺孔39にする。さらに、スクリュー20をねじ込むと、スクリュー20のねじ頭21は突出部53に接触し、スクリュー20の、貫通孔51から螺孔39の方向への移動は止められる。この状態で、さらにスクリュー20をねじ込むと、スクリュー20は、突出部53を螺孔側薄板35の方向に押し付け、これにより、貫通孔側薄板50全体が螺孔側薄板35の方向に押し付けられる。また、スクリュー20をねじ込むことにより螺孔39には貫通孔側薄板50の方向に押し付けられる力が作用し、螺孔側薄板35における螺孔39周辺の全体に、貫通孔側薄板50の方向に押し付けられる力が作用する。これらにより、スクリュー20のねじ部22と螺孔39とは螺合し、貫通孔側薄板50と螺孔側薄板35とは締結される。   The screw 20 passes the screw portion 22 through the through hole 51 from the surface on the protruding portion 53 side of the through hole side thin plate 50 overlapped with the screw hole side thin plate 35 in this way, and the screw portion 22 is further passed through the screw hole side thin plate 35. The lower hole 38 is turned into a screw hole 39 while being screwed into the lower hole 38 formed in the above. Further, when the screw 20 is screwed in, the screw head 21 of the screw 20 comes into contact with the protruding portion 53, and the movement of the screw 20 in the direction from the through hole 51 to the screw hole 39 is stopped. When the screw 20 is further screwed in this state, the screw 20 presses the projecting portion 53 in the direction of the screw hole side thin plate 35, whereby the entire through hole side thin plate 50 is pressed in the direction of the screw hole side thin plate 35. Further, when the screw 20 is screwed in, a force that is pressed in the direction of the through hole side thin plate 50 acts on the screw hole 39, and the entire periphery of the screw hole 39 in the screw hole side thin plate 35 is directed in the direction of the through hole side thin plate 50. A pressing force is applied. As a result, the screw portion 22 of the screw 20 and the screw hole 39 are screwed together, and the through hole side thin plate 50 and the screw hole side thin plate 35 are fastened.

また、この状態では、スクリュー20のねじ頭21と貫通孔51とは離間しており、これに伴い、ねじ頭21は、螺孔39とも距離が離れている。このため、スクリュー20の不完全ねじ部25の大部分を、螺孔39よりもねじ頭21寄りの部分に位置させることができ、スクリュー20のねじ部22と螺孔39とを、より確実に螺合することができる。さらに、突出部53は貫通孔側薄板50にのみ設けられ、スクリュー20のねじ頭21に接触するのみなので、突出部53を高い精度で製造する必要がなく、容易に製造することができる。これらの結果、薄板1同士を、容易に、且つ、より確実に締結することができる。   Further, in this state, the screw head 21 of the screw 20 and the through hole 51 are separated from each other, and accordingly, the screw head 21 is also separated from the screw hole 39 by a distance. For this reason, most of the incomplete thread portion 25 of the screw 20 can be positioned closer to the screw head 21 than the screw hole 39, and the screw portion 22 and the screw hole 39 of the screw 20 can be more reliably connected. Can be screwed together. Furthermore, since the protrusion part 53 is provided only in the through-hole side thin plate 50, and only contacts the screw head 21 of the screw 20, the protrusion part 53 does not need to be manufactured with high precision and can be manufactured easily. As a result, the thin plates 1 can be easily and more securely fastened.

図10は、図9の突出部の変形例を示す図である。なお、このように貫通孔側薄板50に形成される突出部は、貫通孔51の周囲の全周に連続して形成されていなくてもよく、複数の突出部53を貫通孔51の周囲において互いに離間させて形成してもよい。突出部53は、例えば図10に示すように、貫通孔51の周囲の3箇所に等間隔で形成されていてもよい。スクリュー20のサイズが小さく、貫通孔51の大きさが小さいなどの理由により、突出部53を貫通孔51の周囲の全周に設けることが困難である場合には、複数の突出部53を離間させて形成することにより、突出部53を容易に設けることができる。なお、このように離間して形成される突出部53は、貫通孔51の周囲の3箇所以外でもよく、貫通孔51の周囲の2箇所に設けたり、4箇所以上に設けたりしてもよい。   FIG. 10 is a view showing a modification of the protruding portion of FIG. Note that the protrusions formed on the through-hole side thin plate 50 in this way may not be formed continuously around the entire circumference of the through-hole 51, and the plurality of protrusions 53 may be formed around the through-hole 51. You may form mutually spaced apart. For example, as shown in FIG. 10, the protruding portions 53 may be formed at three equal intervals around the through hole 51. If it is difficult to provide the protrusions 53 around the entire circumference of the through hole 51 due to the small size of the screw 20 and the small size of the through hole 51, the plurality of protrusions 53 are separated from each other. Thus, the protrusion 53 can be easily provided. In addition, the protruding portions 53 formed so as to be separated from each other may be other than the three places around the through hole 51, may be provided at two places around the through hole 51, or may be provided at four or more places. .

また、上記の薄板1は金属材料からなり、バーリング部13、37、43が形成される薄板1である螺孔側薄板10、35、40も金属材料により形成されているが、螺孔側薄板10、35、40は、樹脂材料によって形成してもよい。螺孔側薄板10、35、40が金属材料からなる場合には、バーリング部13、37、43は板金加工により形成されるため、その高さをあまり高くすることができず、螺孔15、39、45の深さも深くすることが困難である。そこで、螺孔側薄板を樹脂材料で形成することにより、バーリング部も樹脂材料によって形成されるので、その高さの自由が向上する。これにより、螺孔の深さの設定も自由度が向上するので、螺孔の深さを深くすることができ、螺孔とスクリュー20のねじ山23とが螺合する部分を、より多くすることができる。この結果、薄板1同士を、容易に、且つ、より確実に締結することができる。   The thin plate 1 is made of a metal material, and the screw hole side thin plates 10, 35, and 40, which are the thin plate 1 on which the burring portions 13, 37, and 43 are formed, are also formed of a metal material. 10, 35 and 40 may be formed of a resin material. When the screw hole side thin plates 10, 35, 40 are made of a metal material, the burring portions 13, 37, 43 are formed by sheet metal processing, so that the height thereof cannot be increased so much. It is difficult to make the depths 39 and 45 deeper. Therefore, by forming the screw hole side thin plate with a resin material, the burring portion is also formed with the resin material, so that the freedom of its height is improved. Thereby, since the freedom degree also improves the setting of the depth of a screw hole, the depth of a screw hole can be deepened and the part which the screw hole and the screw thread 23 of the screw 20 screw together is increased. be able to. As a result, the thin plates 1 can be easily and more securely fastened.

また、上述した締結構造では、締結手段であるスクリュー20として、下孔にねじ込むことにより、下孔に当該スクリュー20に形成されるねじ山23とほぼ同形状の螺旋状の溝を形成するセルフタップねじを用いているが、締結手段は、セルフタップねじ以外のものを用いてもよい。例えば、螺孔側薄板には予め螺孔が形成されており、締結手段は、この螺孔に螺合可能なスクリューを用いてもよい。このような、セルフタップねじ以外のスクリューでも、不完全ねじ部を有する場合があるので、締結部材である板などの厚さが薄い場合には、不完全ねじ部が螺孔にかかる虞がある。このため、スクリューを通す貫通孔と螺孔とを離間させることにより、不完全ねじ部が螺孔にかかることを抑制できる。この結果、締結部材同士を、容易に、且つ、より確実に締結することができる。   Moreover, in the fastening structure mentioned above, the self tap which forms the helical groove | channel of the substantially same shape as the screw thread 23 formed in the said screw 20 in a lower hole by screwing in the lower hole as the screw 20 which is a fastening means. Although a screw is used, a fastening means other than a self-tapping screw may be used. For example, a screw hole may be formed in advance in the screw hole side thin plate, and a screw that can be screwed into the screw hole may be used as the fastening means. Such a screw other than the self-tapping screw may have an incomplete screw portion, and therefore, if the thickness of the plate as a fastening member is thin, the incomplete screw portion may be applied to the screw hole. . For this reason, it can suppress that an incomplete thread part hits a screw hole by separating the penetration hole and screw hole which let a screw pass. As a result, the fastening members can be easily and more reliably fastened.

また、締結部材である薄板は、貫通孔側薄板と螺孔側薄板とに2枚になっているが、薄板は2枚よりも多くてもよい。例えば、貫通孔側薄板と螺孔側薄板との間に、貫通孔が形成された他の薄板を設けてもよい。本発明の締結構造によって締結される薄板は、2枚よりも多い数であってもよい。   Moreover, although the thin plate which is a fastening member is two sheets, the through-hole side thin plate and the screw hole side thin plate, there may be more than two sheets. For example, another thin plate in which a through hole is formed may be provided between the through hole side thin plate and the screw hole side thin plate. The number of thin plates fastened by the fastening structure of the present invention may be more than two.

上述した説明で明らかなように、締結構造が、2枚を重ねて締結可能な締結部材である薄板1と、2枚の薄板1のうち一方の薄板1に形成される貫通孔6と、2枚の薄板1のうち他方の薄板1に形成される螺合部である下孔14または螺孔15と、2枚の薄板1のうち1枚の薄板1に形成されると共に貫通孔6と下孔14などの螺合部とを離間させ、且つ、弾力性を有する突出部12と、突出部12が有し、貫通孔6と螺合部である螺孔15との接触を抑制する補強部である突出部平面部16とバーリング部13と、を具備することにより、締結手段であるスクリュー20を貫通孔6に通し、下孔14にねじ込んで下孔14を螺孔15にして螺合させた場合、スクリュー20の不完全ねじ部25の大部分は、貫通孔6の内側、及び貫通孔6と螺孔15との間に位置する。これにより、スクリュー20と螺孔15とは、より確実に螺合する。また、突出部12が弾力性を有しているため、螺孔15にスクリュー20をねじ込んだ際に突出部12は弾性変形をし、この突出部12の弾性変形が元の形状に戻ろうとする弾性力により、2枚の薄板1は互いに他方の薄板1に押し付けられる。また、突出部12が弾力性を有していることにより、スクリュー20の緩みを抑制できる。その際に、突出部12は突出部平面部16とバーリング部13とによって補強されているので、大きく弾性変形して貫通孔6と螺孔15とが接触することが抑制され、より確実にスクリュー20の不完全ねじ部25を、貫通孔6の内側、及び貫通孔6と螺孔15との間に位置させることができる。さらに、突出部12は1枚の薄板1にのみ設けられているので、突出部12を高い精度で製造する必要がなく、容易に製造することができる。これらの結果、締結部材である薄板1同士を、容易に、且つ、より確実に締結することができる。   As apparent from the above description, the fastening structure is a thin plate 1 that is a fastening member that can be fastened by overlapping two pieces, a through hole 6 formed in one thin plate 1 of the two thin plates 1, and 2 A lower hole 14 or a screw hole 15 which is a screwing portion formed in the other thin plate 1 of the two thin plates 1, and a through hole 6 and a lower portion formed in one thin plate 1 of the two thin plates 1. A reinforcing part that separates the threaded part such as the hole 14 and has elasticity, and a reinforcing part that the projecting part 12 has and suppresses contact between the through hole 6 and the screw hole 15 that is the threaded part. By providing the projecting portion flat portion 16 and the burring portion 13, the screw 20 as the fastening means is passed through the through hole 6 and screwed into the lower hole 14 to be screwed into the lower hole 14 as the screw hole 15. In this case, most of the incomplete thread portion 25 of the screw 20 is formed inside the through hole 6 and the through hole 6. Located between the hole 15. Thereby, the screw 20 and the screw hole 15 are more reliably screwed together. Further, since the protruding portion 12 has elasticity, the protruding portion 12 undergoes elastic deformation when the screw 20 is screwed into the screw hole 15, and the elastic deformation of the protruding portion 12 attempts to return to the original shape. The two thin plates 1 are pressed against each other by the elastic force. Moreover, the looseness of the screw 20 can be suppressed by the protrusion 12 having elasticity. At this time, since the protrusion 12 is reinforced by the protrusion flat portion 16 and the burring portion 13, the elastic deformation is greatly suppressed and the contact between the through hole 6 and the screw hole 15 is suppressed, and the screw is more reliably secured. The 20 incomplete thread portions 25 can be positioned inside the through hole 6 and between the through hole 6 and the screw hole 15. Furthermore, since the protruding portion 12 is provided only on one thin plate 1, it is not necessary to manufacture the protruding portion 12 with high accuracy and can be easily manufactured. As a result, the thin plates 1 that are fastening members can be easily and more reliably fastened.

上述した説明で明らかなように、締結構造が、2枚を重ねて締結可能な締結部材である薄板1と、2枚の薄板1のうち一方の薄板1に形成される貫通孔6と、2枚の薄板1のうち他方の薄板1に形成される螺合部である下孔38または螺孔39と、貫通孔6が形成された薄板1に設けられると共に2枚の薄板1を締結する際に下孔38などの螺合部が形成された薄板1が位置する方向と反対方向に突出している突出部53と、突出部53に設けられ、螺合部が形成された薄板1と突出部53との接触を抑制する補強部である突出部壁部54と、を具備することにより、締結手段であるスクリュー20を貫通孔6に通し、下孔38にねじ込んで下孔38を螺孔39にして螺合させ、この状態でスクリュー20をねじ込んだ場合、スクリュー20が有するねじ頭21は突出部53に接触する。この状態では、スクリュー20の不完全ねじ部25の大部分は、螺孔39よりもねじ頭21寄りの部分に位置するので、スクリュー20と螺孔39とは、より確実に螺合する。さらに、突出部53は1枚の薄板1にのみ設けられ、スクリュー20のねじ頭21に接触するのみなので、突出部53を高い精度で製造する必要がなく、容易に製造することができる。これらの結果、薄板1同士を、容易に、且つ、より確実に締結することができる。   As apparent from the above description, the fastening structure is a thin plate 1 that is a fastening member that can be fastened by overlapping two pieces, a through hole 6 formed in one thin plate 1 of the two thin plates 1, and 2 When the two thin plates 1 are fastened together with the lower hole 38 or the screw hole 39 which is a screwing portion formed in the other thin plate 1 of the thin plates 1 and the thin plate 1 in which the through holes 6 are formed. A protrusion 53 protruding in a direction opposite to the direction in which the thin plate 1 in which a screwed portion such as a lower hole 38 is formed is positioned, and the thin plate 1 provided in the protruding portion 53 and formed with a screwed portion. By providing the protruding portion wall portion 54 that is a reinforcing portion that suppresses contact with 53, the screw 20 that is a fastening means is passed through the through hole 6 and screwed into the lower hole 38, and the lower hole 38 is screwed into the screw hole 39. When the screw 20 is screwed in this state, the screw 20 Screw head 21 having contacts the protruding portion 53. In this state, most of the incomplete threaded portion 25 of the screw 20 is positioned closer to the screw head 21 than the screw hole 39, so that the screw 20 and the screw hole 39 are more reliably screwed together. Furthermore, since the protrusion 53 is provided only on one thin plate 1 and only contacts the screw head 21 of the screw 20, the protrusion 53 does not need to be manufactured with high accuracy and can be easily manufactured. As a result, the thin plates 1 can be easily and more securely fastened.
