FIG. 9 is a cross-sectional view of a main part of the decorative panel according to the first embodiment.
　図７において、図６におけるＸ－Ｘ断面が示される。 In FIG. 7, the XX cross section in FIG. 6 is shown.
　締結作業を行う作業員は、締結具４を組み立てる。締結具４の組立において、作業員は、第１座金１４を第２座金１５の仮支持部１８に仮支持させることによって座金体９を組立てる。作業員は、例えば第１座金１４を押し込むことで仮支持部１８にはめ込んで仮支持させる。作業員は、ボルト７のネジ部１０を、組立てた座金体９の仮支持部１８の側から筒部１７に通す。作業員は、ボルト７のネジ部１０をナット８に通す。このとき、ナット８は、緩んだ状態でネジ部１０に保持されている。このとき、座金体９は、ネジ部１０に沿って移動可能に保持されている。 The worker performing the fastening work assembles the fastener 4. In assembling the fastener 4, the worker assembles the washer body 9 by temporarily supporting the first washer 14 with the temporary support portion 18 of the second washer 15. For example, the worker pushes in the first washer 14 to fit it into the temporary support portion 18 and temporarily support it. The worker passes the screw portion 10 of the bolt 7 through the tubular portion 17 from the side of the temporary support portion 18 of the assembled washer body 9. The worker passes the screw portion 10 of the bolt 7 through the nut 8. At this time, the nut 8 is held by the screw portion 10 in a loosened state. At this time, the washer body 9 is movably held along the screw portion 10.
　作業員は、組立てた締結具４を、ボルト７の頭部１１の側から締結孔６の大径部１２に入れる。作業員は、ボルト７の頭部１１を、一対の化粧パネル２の反対側まで通す。このとき、外径が幅Ｗ２より大きいつば部１６は、締結孔６の大径部１２を通らない。その後、作業員は、締結孔６の大径部１２に通した締結具４を、小径部１３に移動させる。 The worker inserts the assembled fastener 4 into the large diameter portion 12 of the fastening hole 6 from the side of the head 11 of the bolt 7. The worker passes the head 11 of the bolt 7 to the opposite side of the pair of decorative panels 2. At this time, the brim portion 16 having an outer diameter larger than the width W2 does not pass through the large diameter portion 12 of the fastening hole 6. After that, the worker moves the fastener 4 passed through the large diameter portion 12 of the fastening hole 6 to the small diameter portion 13.
　図８は、小径部１３に移動した締結具４を、ナット８の側から見た図である。 FIG. 8 is a view of the fastener 4 moved to the small diameter portion 13 as viewed from the side of the nut 8.
　作業員は、第１座金１４が一対の化粧パネル２の間に配置されるように座金体９の位置または一対の化粧パネル２の間隔を調整しながら、締結具４を小径部１３に移動させる。作業員は、小径部１３に移動させた締結具４のナット８を締め込む。 The worker moves the fastener 4 to the small diameter portion 13 while adjusting the position of the washer body 9 or the distance between the pair of decorative panels 2 so that the first washer 14 is arranged between the pair of decorative panels 2. .. The worker tightens the nut 8 of the fastener 4 that has been moved to the small diameter portion 13.
　図９において、小径部１３を通り第２方向に垂直な平面による断面図が示される。図９において、締結具４によって締結された状態の一対の化粧パネル２が示される。 In FIG. 9, a cross-sectional view taken along a plane passing through the small diameter portion 13 and perpendicular to the second direction is shown. In FIG. 9, a pair of decorative panels 2 in a state of being fastened by the fastener 4 is shown.
　締め込まれるナット８によって、つば部１６は、化粧パネル２に押し付けられる。このとき、外径が幅Ｗ１より大きいつば部１６は、締結孔６の小径部１３を通らない。ナット８が締め込まれることによって、ナット８および頭部１１の間隔が狭くなる。これにより、一対の化粧パネル２の間隔が狭くなる。ナット８が締め込まれることによって、小径部１３の縁は、第１座金１４に接触する。このとき、外径が幅Ｗ１より大きい第１座金１４は、締結孔６の小径部１３を通らない。さらにナット８が締め込まれることによって、小径部１３の縁は、第１座金１４をナット８の側に押し付ける。さらにナット８が締め込まれることによって、仮支持部１８に仮支持されていた第１座金１４は、つば部１６の側に外れる。このとき、筒部１７の先端は、頭部１１の溝２０にはまり込む。第１座金１４は、一対の化粧パネル２の間に配置される。さらにナット８が締め込まれることによって、一対の化粧パネル２は、第１座金１４の板厚の間隔を保った状態で締結される。 The brim portion 16 is pressed against the decorative panel 2 by the nut 8 to be tightened. At this time, the brim portion 16 having an outer diameter larger than the width W1 does not pass through the small diameter portion 13 of the fastening hole 6. By tightening the nut 8, the distance between the nut 8 and the head 11 is narrowed. As a result, the distance between the pair of decorative panels 2 is narrowed. By tightening the nut 8, the edge of the small diameter portion 13 comes into contact with the first washer 14. At this time, the first washer 14 having an outer diameter larger than the width W1 does not pass through the small diameter portion 13 of the fastening hole 6. Further, as the nut 8 is tightened, the edge of the small diameter portion 13 presses the first washer 14 toward the nut 8. Further, when the nut 8 is tightened, the first washer 14 temporarily supported by the temporary support portion 18 is released to the side of the brim portion 16. At this time, the tip of the tubular portion 17 fits into the groove 20 of the head portion 11. The first washer 14 is arranged between the pair of decorative panels 2. Further, by tightening the nut 8, the pair of decorative panels 2 are fastened while maintaining the interval of the plate thickness of the first washer 14.
　以上に説明したように、実施の形態１に係る締結具４は、ボルト７と、ナット８と、座金体９と、を備える。一対の化粧パネル２の各々は、締結孔６を有する。締結孔６において、大径部１２および小径部１３は、第２方向において連なる。小径部１３の第１方向の幅Ｗ１は、大径部１２の第１方向の幅Ｗ２より小さい。第１方向は、締結孔６が設けられる締結部５の面内の方向である。第２方向は、第１方向に直交する方向である。第２方向は、締結孔６が設けられる締結部５の面内の方向である。ボルト７は、ネジ部１０および頭部１１を有する。ネジ部１０は、一対の化粧パネル２の各々の小径部１３に通される。頭部１１の外径は、大径部１２を通り且つ小径部１３を通らない径である。頭部１１は、ネジ部１０の一端に設けられる。ナット８は、ネジ部１０に締め込まれる。座金体９は、第１座金１４および第２座金１５を有する。第１座金１４の形状は、環状である。第１座金１４の外径は、大径部１２を通り且つ小径部１３を通らない径である第２座金１５は、つば部１６と、筒部１７と、仮支持部１８と、を備える。つば部１６の形状は、環状である。つば部１６の外径は、大径部１２を通らない径である。筒部１７は、頭部１１およびナット８の間においてネジ部１０に通される。筒部１７の外径は、小径部１３を通る径である。筒部１７は、つば部１６の内側の縁からナット８の側に延びる。仮支持部１８は、筒部１７においてつば部１６から化粧パネル２の板厚より離れた位置に設けられる。仮支持部１８は、第１座金１４の内側の縁を仮支持する。 As described above, the fastener 4 according to the first embodiment includes a bolt 7, a nut 8, and a washer body 9. Each of the pair of decorative panels 2 has a fastening hole 6. In the fastening hole 6, the large diameter portion 12 and the small diameter portion 13 are connected in the second direction. The width W1 of the small diameter portion 13 in the first direction is smaller than the width W2 of the large diameter portion 12 in the first direction. The first direction is the in-plane direction of the fastening portion 5 in which the fastening hole 6 is provided. The second direction is a direction orthogonal to the first direction. The second direction is the in-plane direction of the fastening portion 5 in which the fastening hole 6 is provided. The bolt 7 has a threaded portion 10 and a head portion 11. The screw portion 10 is passed through each of the small diameter portions 13 of the pair of decorative panels 2. The outer diameter of the head 11 is a diameter that passes through the large diameter portion 12 and does not pass through the small diameter portion 13. The head portion 11 is provided at one end of the screw portion 10. The nut 8 is tightened to the screw portion 10. The washer body 9 has a first washer 14 and a second washer 15. The shape of the first washer 14 is annular. The outer diameter of the first washer 14 is a diameter that passes through the large diameter portion 12 and does not pass through the small diameter portion 13. The second washer 15 includes a brim portion 16, a tubular portion 17, and a temporary support portion 18. The shape of the brim 16 is annular. The outer diameter of the brim portion 16 is a diameter that does not pass through the large diameter portion 12. The tubular portion 17 is passed through the threaded portion 10 between the head portion 11 and the nut 8. The outer diameter of the tubular portion 17 is a diameter that passes through the small diameter portion 13. The tubular portion 17 extends from the inner edge of the brim portion 16 to the side of the nut 8. The temporary support portion 18 is provided in the tubular portion 17 at a position separated from the brim portion 16 by the thickness of the decorative panel 2. The temporary support portion 18 temporarily supports the inner edge of the first washer 14.
　一対の化粧パネル２の間に配置される座金体９の第１座金１４は、締結具４のボルト７とともに化粧パネル２の締結孔６の大径部１２に通される。第１座金１４は、一対の化粧パネル２の間に配置される。一対の化粧パネル２は、締結孔６の小径部１３において第１座金１４を間に挟んで締結される。このように、締結具４は、一体に組立てられた状態で一対の化粧パネル２の締結孔６に通される。これにより、化粧パネル２の締結がしやすくなる。また、一対の化粧パネル２の各々の締結部５において化粧面３が直接的に接触しない。これにより、締結部５の広い範囲において面圧による化粧面３のクリープが発生しにくい。このため、化粧面３の遊離の発生が抑制される。 The first washer 14 of the washer body 9 arranged between the pair of decorative panels 2 is passed through the large diameter portion 12 of the fastening hole 6 of the decorative panel 2 together with the bolt 7 of the fastener 4. The first washer 14 is arranged between the pair of decorative panels 2. The pair of decorative panels 2 are fastened with the first washer 14 sandwiched between the small diameter portions 13 of the fastening holes 6. In this way, the fastener 4 is passed through the fastening holes 6 of the pair of decorative panels 2 in a state of being integrally assembled. This makes it easier to fasten the decorative panel 2. Further, the decorative surface 3 does not come into direct contact with each of the fastening portions 5 of the pair of decorative panels 2. As a result, creep of the decorative surface 3 due to surface pressure is unlikely to occur in a wide range of the fastening portion 5. Therefore, the occurrence of release of the decorative surface 3 is suppressed.
　また、頭部１１は、環状の溝２０を有する。環状の溝２０は、つば部１６から延びる筒部１７の端部がはまり込む溝である。 Further, the head 11 has an annular groove 20. The annular groove 20 is a groove into which the end of the tubular portion 17 extending from the brim portion 16 fits.
　これにより、締結具４のボルト７が、例えば角根ボルトなどのように小径部１３との間に隙間が設けられない構造であっても、作業員は第１座金１４が仮支持部１８から外れるまでナット８を締め込むことができる。 As a result, even if the bolt 7 of the fastener 4 has a structure such as a square root bolt in which a gap is not provided between the bolt 7 and the small diameter portion 13, the worker can move the first washer 14 from the temporary support portion 18. The nut 8 can be tightened until it comes off.
　なお、例えばボルト７の頭部１１が根部１９を有していない場合などにおいて、筒部１７の長さが化粧パネル２の締結孔６から端部が突出しない長さであるときに、頭部１１は、環状の溝を有していなくてもよい。 For example, when the head portion 11 of the bolt 7 does not have the root portion 19, the length of the tubular portion 17 is such that the end portion does not protrude from the fastening hole 6 of the decorative panel 2. 11 does not have to have an annular groove.

　締め込まれるナット８によって、第１つば部２１は、化粧パネル２に押し付けられる。このとき、外径が幅Ｗ１より大きい第１つば部２１は、締結孔６の小径部１３を通らない。ナット８が締め込まれることによって、ナット８および頭部１１の間隔が狭くなる。これにより、一対の化粧パネル２の間隔が狭くなる。ナット８が締め込まれることによって、小径部１３の縁は第２つば部２２に接触する。このとき、外径が幅Ｗ１より大きい第２つば部２２は、締結孔６の小径部１３を通らない。さらにナット８が締め込まれることによって、小径部１３の縁は、第２つば部２２をナット８の側に押し付ける。さらにナット８が締め込まれることによって、第２つば部２２は、ミクロジョイント２３の部分において筒部１７から切り離される。このとき、第２つば部２２は、第１つば部２１の側に移動する。筒部１７の先端は、頭部１１の溝２０にはまり込む。第２つば部２２は、一対の化粧パネル２の間に配置される。さらにナット８が締め込まれることによって、一対の化粧パネル２は、第２つば部２２の板厚の間隔を保った状態で締結される。 The first brim portion 21 is pressed against the decorative panel 2 by the nut 8 to be tightened. At this time, the first brim portion 21 having an outer diameter larger than the width W1 does not pass through the small diameter portion 13 of the fastening hole 6. By tightening the nut 8, the distance between the nut 8 and the head 11 is narrowed. As a result, the distance between the pair of decorative panels 2 is narrowed. By tightening the nut 8, the edge of the small diameter portion 13 comes into contact with the second brim portion 22. At this time, the second brim portion 22 having an outer diameter larger than the width W1 does not pass through the small diameter portion 13 of the fastening hole 6. Further, as the nut 8 is tightened, the edge of the small diameter portion 13 presses the second brim portion 22 toward the nut 8. Further, by tightening the nut 8, the second brim portion 22 is separated from the tubular portion 17 at the portion of the micro joint 23. At this time, the second brim portion 22 moves to the side of the first brim portion 21. The tip of the tubular portion 17 fits into the groove 20 of the head portion 11. The second brim portion 22 is arranged between the pair of decorative panels 2. Further, by tightening the nut 8, the pair of decorative panels 2 are fastened while maintaining the interval of the plate thickness of the second brim portion 22.

Each of the pair of decorative panels 2 has a fastening hole 6. In the fastening hole 6, the large diameter portion 12 and the small diameter portion 13 are connected in the second direction. The width W1 of the small diameter portion 13 in the first direction is smaller than the width W2 of the large diameter portion 12 in the first direction. The first direction is the in-plane direction of the fastening portion 5 in which the fastening hole 6 is provided. The second direction is a direction orthogonal to the first direction. The second direction is the in-plane direction of the fastening portion 5 in which the fastening hole 6 is provided. The bolt 7 has a threaded portion 10 and a head portion 11. The screw portion 10 is passed through each of the small diameter portions 13 of the pair of decorative panels 2. The outer diameter of the head 11 is a diameter that passes through the large diameter portion 12 and does not pass through the small diameter portion 13. The head portion 11 is provided at one end of the screw portion 10. The nut 8 is tightened to the screw portion 10. The washer body 9 has a first brim portion 21, a tubular portion 17, and a second brim portion 22. The shape of the first brim portion 21 is annular. The outer diameter of the first brim portion 21 is a diameter that does not pass through the large diameter portion 12. The tubular portion 17 is passed through the threaded portion 10 between the head portion 11 and the nut 8. The outer diameter of the tubular portion 17 is a diameter that passes through the small diameter portion 13. The tubular portion 17 extends in the axial direction of the threaded portion 10 from the inner edge of the first brim portion 21. The shape of the second brim portion 22 is annular. The outer diameter of the second brim portion 22 is a diameter that passes through the large diameter portion 12 and does not pass through the small diameter portion 13. The second brim portion 22 is provided in the tubular portion 17 so as to be detachable from the first brim portion 21 at a position separated from the thickness of the decorative panel 2.
　一対の化粧パネル２の間に配置される座金体９の第２つば部２２は、締結具４のボルト７とともに化粧パネル２の締結孔６の大径部１２に通される。第２つば部２２は、一対の化粧パネル２の間に配置される。一対の化粧パネル２は、締結孔６の小径部１３において第２つば部２２を間に挟んで締結される。このように、締結具４は、一体に組立てられた状態で一対の化粧パネル２の締結孔６に通される。これにより、化粧パネル２の締結がしやすくなる。また、一対の化粧パネル２の各々の締結部５において化粧面３が直接的に接触しない。これにより、締結部５の広い範囲において面圧による化粧面３のクリープが発生しにくい。このため、化粧面３の遊離の発生が抑制される。また、座金体９は、一体の部品によって構成される。このため、締結具４を部品点数がより少ない簡易な構造によって構成できる。 The second brim portion 22 of the washer body 9 arranged between the pair of decorative panels 2 is passed through the large diameter portion 12 of the fastening hole 6 of the decorative panel 2 together with the bolt 7 of the fastener 4. The second brim portion 22 is arranged between the pair of decorative panels 2. The pair of decorative panels 2 are fastened with the second brim portion 22 sandwiched between the small diameter portions 13 of the fastening holes 6. In this way, the fastener 4 is passed through the fastening holes 6 of the pair of decorative panels 2 in a state of being integrally assembled. This makes it easier to fasten the decorative panel 2. Further, the decorative surface 3 does not come into direct contact with each of the fastening portions 5 of the pair of decorative panels 2. As a result, creep of the decorative surface 3 due to surface pressure is unlikely to occur in a wide range of the fastening portion 5. Therefore, the occurrence of release of the decorative surface 3 is suppressed. Further, the washer body 9 is composed of an integral part. Therefore, the fastener 4 can be configured with a simple structure having a smaller number of parts.
　また、頭部１１は、環状の溝２０を有する。環状の溝２０は、第１つば部２１から延びる筒部１７の端部がはまり込む溝２０である。 Further, the head 11 has an annular groove 20. The annular groove 20 is a groove 20 into which the end of the tubular portion 17 extending from the first brim portion 21 fits.
　これにより、締結具４のボルト７が、例えば角根ボルトなどのように小径部１３との間に隙間が設けられない構造であっても、作業員は、第２つば部２２が筒部１７から切り離されるまでナット８を締め込むことができる。 As a result, even if the bolt 7 of the fastener 4 has a structure in which a gap is not provided between the bolt 7 and the small diameter portion 13 such as a square root bolt, the worker can use the second brim portion 22 as the tubular portion 17 for the worker. The nut 8 can be tightened until it is separated from.
　なお、例えばボルト７の頭部１１が根部１９を有していない場合などにおいて、筒部１７の長さが化粧パネル２の締結孔６から端部が突出しない長さであるときに、頭部１１は、環状の溝を有していなくてもよい。 For example, when the head portion 11 of the bolt 7 does not have the root portion 19, the length of the tubular portion 17 is such that the end portion does not protrude from the fastening hole 6 of the decorative panel 2. 11 does not have to have an annular groove.

　図１７および図１８は、実施の形態３に係る化粧パネル２の要部拡大図である。
　図１９は、実施の形態３に係る化粧パネル２の要部断面図である。 Subsequently, fastening by the fastener 4 will be described with reference to FIGS. 17 to 19.
17 and 18 are enlarged views of a main part of the decorative panel 2 according to the third embodiment.
FIG. 19 is a cross-sectional view of a main part of the decorative panel 2 according to the third embodiment.
　図１７において、図１６におけるＹ－Ｙ断面が示される。 In FIG. 17, the YY cross section in FIG. 16 is shown.
　締結作業を行う作業員は、締結具４を組み立てる。作業員は、ボルト７のネジ部１０を座金体９の複数の板部２４が延びる側から通す。作業員は、ボルト７のネジ部１０をナット８に通す。このとき、ナット８は、緩んだ状態でネジ部１０に保持されている。このとき、座金体９は、ネジ部１０に沿って移動可能に保持されている。 The worker performing the fastening work assembles the fastener 4. The worker passes the screw portion 10 of the bolt 7 from the side where the plurality of plate portions 24 of the washer body 9 extend. The worker passes the screw portion 10 of the bolt 7 through the nut 8. At this time, the nut 8 is held by the screw portion 10 in a loosened state. At this time, the washer body 9 is movably held along the screw portion 10.
　作業員は、組立てた締結具４を、ボルト７の頭部１１の側から締結孔６の大径部１２に入れる。作業員は、ボルト７の頭部１１を、一対の化粧パネル２の反対側まで通す。このとき、外径が幅Ｗ２より大きいつば部１６は、締結孔６の大径部１２を通らない。その後、作業員は、締結孔６の大径部１２に通した締結具４を、小径部１３に移動させる。 The worker inserts the assembled fastener 4 into the large diameter portion 12 of the fastening hole 6 from the side of the head 11 of the bolt 7. The worker passes the head 11 of the bolt 7 to the opposite side of the pair of decorative panels 2. At this time, the brim portion 16 having an outer diameter larger than the width W2 does not pass through the large diameter portion 12 of the fastening hole 6. After that, the worker moves the fastener 4 passed through the large diameter portion 12 of the fastening hole 6 to the small diameter portion 13.
　図１８は、小径部１３に移動した締結具４を、ナット８の側から見た図である。 FIG. 18 is a view of the fastener 4 moved to the small diameter portion 13 as viewed from the side of the nut 8.
　作業員は、複数の板部２４の各々の端部が一対の化粧パネル２の間に配置されるように座金体９の位置または一対の化粧パネル２の間隔を調整しながら、締結具４を小径部１３に移動させる。作業員は、小径部１３に移動させた締結具４のナット８を締め込む。 The worker adjusts the position of the washer 9 or the distance between the pair of decorative panels 2 so that each end of the plurality of plate portions 24 is arranged between the pair of decorative panels 2, and the fastener 4 is attached. It is moved to the small diameter portion 13. The worker tightens the nut 8 of the fastener 4 that has been moved to the small diameter portion 13.
　図１９において、小径部１３を通り第２方向に垂直な平面による断面図が示される。図９において、締結具４によって締結された状態の一対の化粧パネル２が示される。 In FIG. 19, a cross-sectional view taken along a plane passing through the small diameter portion 13 and perpendicular to the second direction is shown. In FIG. 9, a pair of decorative panels 2 in a state of being fastened by the fastener 4 is shown.
　締め込まれるナット８によって、つば部１６は、化粧パネル２に押し付けられる。このとき、外径が幅Ｗ１より大きいつば部１６は、締結孔６の小径部１３を通らない。ナット８が締め込まれることによって、ナット８および頭部１１の間隔が狭くなる。これにより、一対の化粧パネル２の間隔が狭くなる。ナット８が締め込まれることによって、小径部１３の縁は、複数の板部２４の各々の端部に接触する。このとき、幅Ｗ１の直径の円柱領域の外側にはみ出す範囲まで広がっている複数の板部２４の各々の端部は、締結孔６の小径部１３を通らない。さらにナット８が締め込まれることによって、小径部１３の縁は、複数の板部２４の各々の端部をナット８の側に押し付ける。さらにナット８が締め込まれることによって、複数の板部２４の各々は、外側に開くように変形する。複数の板部２４の各々の端部は、一対の化粧パネル２の間に配置される。さらにナット８が締め込まれることによって、一対の化粧パネル２は、板部２４の板厚の間隔を保った状態で締結される。 The brim portion 16 is pressed against the decorative panel 2 by the nut 8 to be tightened. At this time, the brim portion 16 having an outer diameter larger than the width W1 does not pass through the small diameter portion 13 of the fastening hole 6. By tightening the nut 8, the distance between the nut 8 and the head 11 is narrowed. As a result, the distance between the pair of decorative panels 2 is narrowed. By tightening the nut 8, the edge of the small diameter portion 13 comes into contact with each end of the plurality of plate portions 24. At this time, each end of the plurality of plate portions 24 extending to the outside of the cylindrical region having a width W1 does not pass through the small diameter portion 13 of the fastening hole 6. Further, by tightening the nut 8, the edge of the small diameter portion 13 presses each end of the plurality of plate portions 24 toward the nut 8. Further, when the nut 8 is tightened, each of the plurality of plate portions 24 is deformed so as to open outward. Each end of the plurality of plate portions 24 is arranged between the pair of decorative panels 2. Further, by tightening the nut 8, the pair of decorative panels 2 are fastened while maintaining the interval between the plate thicknesses of the plate portions 24.
　以上に説明したように、実施の形態３に係る締結具４は、ボルト７と、ナット８と、座金体９と、を備える。一対の化粧パネル２の各々は、締結孔６を有する。締結孔６において、大径部１２および小径部１３は、第２方向において連なる。小径部１３の第１方向の幅Ｗ１は、大径部１２の第１方向の幅Ｗ２より小さい。第１方向は、締結孔６が設けられる締結部５の面内の方向である。第２方向は、第１方向に直交する方向である。第２方向は、締結孔６が設けられる締結部５の面内の方向である。ボルト７は、ネジ部１０および頭部１１を有する。ネジ部１０は、一対の化粧パネル２の各々の小径部１３に通される。頭部１１の外径は、大径部１２を通り且つ小径部１３を通らない径である。頭部１１は、ネジ部１０の一端に設けられる。ナット８は、ネジ部１０に締め込まれる。座金体９は、つば部１６および複数の板部２４を有する。つば部１６の形状は、環状である。つば部１６の外径は、大径部１２を通らない径である。つば部１６は、頭部１１およびナット８の間においてネジ部１０に通される。複数の板部２４の各々は、つば部１６の内側の縁から外側に拡がるように化粧パネル２の板厚より長く延びる。 As described above, the fastener 4 according to the third embodiment includes a bolt 7, a nut 8, and a washer body 9. Each of the pair of decorative panels 2 has a fastening hole 6. In the fastening hole 6, the large diameter portion 12 and the small diameter portion 13 are connected in the second direction. The width W1 of the small diameter portion 13 in the first direction is smaller than the width W2 of the large diameter portion 12 in the first direction. The first direction is the in-plane direction of the fastening portion 5 in which the fastening hole 6 is provided. The second direction is a direction orthogonal to the first direction. The second direction is the in-plane direction of the fastening portion 5 in which the fastening hole 6 is provided. The bolt 7 has a threaded portion 10 and a head portion 11. The screw portion 10 is passed through each of the small diameter portions 13 of the pair of decorative panels 2. The outer diameter of the head 11 is a diameter that passes through the large diameter portion 12 and does not pass through the small diameter portion 13. The head portion 11 is provided at one end of the screw portion 10. The nut 8 is tightened to the screw portion 10. The washer body 9 has a brim portion 16 and a plurality of plate portions 24. The shape of the brim 16 is annular. The outer diameter of the brim portion 16 is a diameter that does not pass through the large diameter portion 12. The brim portion 16 is passed through the screw portion 10 between the head portion 11 and the nut 8. Each of the plurality of plate portions 24 extends longer than the plate thickness of the decorative panel 2 so as to extend outward from the inner edge of the brim portion 16.
　一対の化粧パネル２の間に配置される座金体９の複数の板部２４の各々は、締結具４のボルト７とともに化粧パネル２の締結孔６の大径部１２に通される。複数の板部２４の各々は、一対の化粧パネル２の間に配置される。一対の化粧パネル２は、締結孔６の小径部１３において複数の板部２４の各々を間に挟んで締結される。このように、締結具４は、一体に組立てられた状態で一対の化粧パネル２の締結孔６に通される。これにより、化粧パネル２の締結がしやすくなる。また、一対の化粧パネル２の各々の締結部５において化粧面３が直接的に接触しない。これにより、締結部５の広い範囲において面圧による化粧面３のクリープが発生しにくい。このため、化粧面３の遊離の発生が抑制される。また、座金体９は、一体の部品によって構成される。このため、締結具４を部品点数がより少ない簡易な構造によって構成できる。 Each of the plurality of plate portions 24 of the washer body 9 arranged between the pair of decorative panels 2 is passed through the large diameter portion 12 of the fastening hole 6 of the decorative panel 2 together with the bolt 7 of the fastener 4. Each of the plurality of plate portions 24 is arranged between the pair of decorative panels 2. The pair of decorative panels 2 are fastened with each of the plurality of plate portions 24 sandwiched between the small diameter portions 13 of the fastening holes 6. In this way, the fastener 4 is passed through the fastening holes 6 of the pair of decorative panels 2 in a state of being integrally assembled. This makes it easier to fasten the decorative panel 2. Further, the decorative surface 3 does not come into direct contact with each of the fastening portions 5 of the pair of decorative panels 2. As a result, creep of the decorative surface 3 due to surface pressure is unlikely to occur in a wide range of the fastening portion 5. Therefore, the occurrence of release of the decorative surface 3 is suppressed. Further, the washer body 9 is composed of an integral part. Therefore, the fastener 4 can be configured with a simple structure having a smaller number of parts.
　なお、複数の板部２４の各々の一部は、締結された一対の化粧パネル２の間に挟まれていなくてもよい。この例において、複数の板部２４のうち大径部１２の方向に延びる板部２４は、一対の化粧パネル２の間に挟まれていなくてもよい。また、作業員は、締結された一対の化粧パネル２の間に複数の板部２４の全てが挟まれるように、座金体９を回転させてからナット８を締め込んでもよい。あるいは、複数の板部２４の各々は、回転対称に設けられなくてもよい。この例において、大径部１２の方向に延びる板部２４は省略してもよい。 Note that each part of the plurality of plate portions 24 does not have to be sandwiched between the pair of decorative panels 2 that have been fastened. In this example, of the plurality of plate portions 24, the plate portion 24 extending in the direction of the large diameter portion 12 does not have to be sandwiched between the pair of decorative panels 2. Further, the worker may rotate the washer body 9 and then tighten the nut 8 so that all of the plurality of plate portions 24 are sandwiched between the pair of decorative panels 2 that have been fastened. Alternatively, each of the plurality of plate portions 24 does not have to be provided rotationally symmetrically. In this example, the plate portion 24 extending in the direction of the large diameter portion 12 may be omitted.
