Description

シールワッシャ付きナットNut with seal washer
　本発明は、ボルトと組み合わせて使用される止水機能を備えたシールワッシャ付きナットに関するものである。 The present invention relates to a nut with a seal washer having a water stop function used in combination with a bolt.
　例えば自動車のボディにリアスポイラーのようなパーツを取付けるためには、ボディに貫通孔を形成してボルトを挿通し、ナットで固定している。ボディとボルトの座面との間には表面に止水用のスポンジを貼り付けたワッシャを介在させ、ボルトと貫通孔との隙間からの水の浸入を防止している。その一例が、特許文献１及び特許文献２に示されている。 For example, to attach a part such as a rear spoiler to the body of an automobile, a through hole is formed in the body, a bolt is inserted, and the part is fixed with a nut. Between the body and the bearing surface of the bolt, a washer with a water-stopping sponge attached is interposed on the surface to prevent water from entering from the gap between the bolt and the through hole. Examples thereof are shown in Patent Document 1 and Patent Document 2.
　ところがこのようなスポンジ付きのワッシャは、相手部材であるボディとの間にメタルタッチ部がないため、弛みが生ずる懸念があった。また、弛まないようにボルトを強く締め付けると、止水用のスポンジが締め付け荷重により変形してしまい、止水機能が損なわれる懸念もあった。さらに、ボルト締結時にスポンジ付きのワッシャを嵌め込まねばならず、締結作業性が悪いという問題があった。 However, such a washer with a sponge has a concern that slack may occur because there is no metal touch part between the body and the counterpart member. Further, if the bolts are tightened strongly so as not to loosen, the water stop sponge is deformed by the tightening load, and there is a concern that the water stop function is impaired. In addition, there is a problem that a washer with a sponge has to be fitted at the time of bolt fastening, and the fastening workability is poor.

　従って本発明の目的は上記した従来の問題点を解決し、弛みが生ずることがなく、安定した止水機能を有し、締結作業性が良好なシールワッシャ付きナットを提供することである。 Therefore, an object of the present invention is to provide a nut with a seal washer that solves the above-mentioned conventional problems, has no water sag, has a stable water stop function, and has a good fastening workability.
　上記の課題を解決するためになされた本発明は、ナット本体の座面側にシールワッシャを取付けたシールワッシャ付きナットであって、このシールワッシャは、外周部の下面が内周部の下面よりも高くなった段付き形状を有し、前記内周部の下面を締結時に相手部材とのメタルタッチ面とし、前記外周部の下面に前記内周部の下面よりも下方に突出する弾性シール材を設けたことを特徴とするものである。 The present invention made to solve the above-mentioned problems is a nut with a seal washer in which a seal washer is attached to the seat surface side of the nut body, and the lower surface of the outer peripheral portion of the seal washer is lower than the lower surface of the inner peripheral portion. An elastic sealing material having a stepped shape that is higher than the lower surface of the inner peripheral portion, the lower surface of the inner peripheral portion being a metal touch surface with a mating member at the time of fastening, and protruding below the lower surface of the inner peripheral portion Is provided.
　なお、請求項２のように、シールワッシャがナット本体の座面側にかしめ固定されている構造であることが好ましく、また請求項３のように、ナット本体をフランジ付きナットとすることができる。 It is preferable that the seal washer is caulked and fixed to the seat surface side of the nut body as in claim 2, and the nut body can be a flanged nut as in claim 3. .
　本発明のシールワッシャ付きナットは、ボルト等の締結具と組み合わせて使用されるものであり、中心孔に挿通されるボルト等によってシールワッシャに軸方向の締結力が加えられると、先ず外周部の下面に設けられた外周部の弾性シール材が圧縮されて相手材の表面に密着する。この状態からさらにシールワッシャに軸方向の締結力が加えられると、シールワッシャの内周部の下面が相手部材とメタルタッチした状態となる。 The nut with a seal washer according to the present invention is used in combination with a fastener such as a bolt, and when an axial fastening force is applied to the seal washer by a bolt inserted through the center hole, The elastic seal material at the outer peripheral portion provided on the lower surface is compressed and adheres to the surface of the counterpart material. When an axial fastening force is further applied to the seal washer from this state, the lower surface of the inner peripheral portion of the seal washer is in a state of metal touch with the counterpart member.
　このように本発明のシールワッシャ付きナットは、締結完了状態においてはシールワッシャの内周部が相手部材とメタルタッチするため、ボルト等に軸力を与えて締結すれば、弛みが生ずることがない。しかも従来とは異なり、外周部の弾性シール材にはそれ以上の圧縮荷重が作用することがないため、外周部の弾性シール材が押し潰されるように変形することもなくなり、止水機能が損なわれることもない。 As described above, the nut with a seal washer according to the present invention is in a state where the inner periphery of the seal washer is in metal contact with the mating member when the fastening is completed. . Moreover, unlike conventional ones, no further compressive load acts on the elastic seal material at the outer peripheral portion, so that the elastic seal material at the outer peripheral portion is not deformed so as to be crushed, and the water stop function is impaired. It will never happen.
　また本発明のシールワッシャ付きナットは、ナット本体の座面側にシールワッシャを取付けた構造であるので、従来のように締結時にワッシャを嵌め込む必要がなく、締結作業性が良好となる。 Further, since the nut with a seal washer according to the present invention has a structure in which a seal washer is attached to the seat surface side of the nut body, it is not necessary to fit the washer at the time of fastening as in the conventional case, and the fastening workability is improved.
　また請求項２のように、シールワッシャをナット本体の座面側にかしめ固定した構造とすれば、シールワッシャとナット本体との間から水が浸入しにくくなる。また請求項３のようにナット本体をフランジ付きナットとしておけば、シールワッシャの外周部まで均一に軸力を作用させることができ、外周部の弾性シール材をより確実に圧縮することができる。 Further, as in claim 2, if the seal washer is caulked and fixed to the seat surface side of the nut body, water will not easily enter between the seal washer and the nut body. If the nut body is a flanged nut as in claim 3, the axial force can be applied uniformly to the outer periphery of the seal washer, and the elastic seal material at the outer periphery can be more reliably compressed.

　以下に本発明の実施形態を説明する。
　図１、図２は本発明の第１の実施形態を示す図である。これらの図において、１はナット本体、２はナット本体１の座面側に取付けられたシールワッシャである。この第１の実施形態におけるナット本体１は六角ナットであり、座面３の下方に突設されたリング状のスカート部４の先端をシールワッシャ２の中心孔５の内側で押し拡げるように塑性変形させ、ナット本体１とシールワッシャ２とをかしめ結合している。スカート部４の先端はシールワッシャ２の下面よりも下方に突出しないようにしておく。 Embodiments of the present invention will be described below.
1 and 2 are diagrams showing a first embodiment of the present invention. In these drawings, 1 is a nut body, and 2 is a seal washer attached to the seat surface side of the nut body 1. The nut body 1 in the first embodiment is a hexagonal nut, and is plastic so that the tip of a ring-shaped skirt portion 4 protruding below the seat surface 3 is pushed inside the center hole 5 of the seal washer 2. The nut body 1 and the seal washer 2 are caulked and joined by deformation. The tip of the skirt portion 4 should not protrude below the lower surface of the seal washer 2.
　このように、シールワッシャ２がナット本体１の座面側にかしめ固定されている構造とすれば、締結作業性が向上するとともに、シールワッシャ２とナット本体１との間から水が浸入しにくくなる利点がある。なお、シールワッシャ２とナット本体１とを溶接により一体化した構造とすることも可能である。 As described above, when the seal washer 2 is caulked and fixed to the seat surface side of the nut body 1, fastening workability is improved and water does not easily enter between the seal washer 2 and the nut body 1. There are advantages. It is also possible to have a structure in which the seal washer 2 and the nut body 1 are integrated by welding.
　シールワッシャ２は円形の金属板であり、ナット本体１のめねじ孔６よりも大径の中心孔５を備えている。シールワッシャ２の上面は平面であってナット本体１の座面３と密着しているが、シールワッシャ２の外周部の下面７は、内周部の下面８よりも高くなった（薄くなった）段付き形状となっている。そしてこの外周部の下面７に、内周部の下面８よりも下方に突出するリング状の弾性シール材１０が設けられている。後述するように、内周部の下面８は締結時に相手部材とのメタルタッチ面となる。 The seal washer 2 is a circular metal plate and includes a center hole 5 having a diameter larger than that of the female screw hole 6 of the nut body 1. The upper surface of the seal washer 2 is flat and is in close contact with the seat surface 3 of the nut body 1, but the lower surface 7 of the outer peripheral portion of the seal washer 2 is higher (thinner) than the lower surface 8 of the inner peripheral portion. ) Stepped shape. A ring-shaped elastic sealing material 10 is provided on the lower surface 7 of the outer peripheral portion and protrudes downward from the lower surface 8 of the inner peripheral portion. As will be described later, the lower surface 8 of the inner peripheral portion becomes a metal touch surface with the mating member at the time of fastening.
　弾性シール材１０の材質は例えばオレフィン系エラストマーであるが、これに限定されるものではなく、ゴム等の一般的なシール材料を使用することができる。また弾性シール材１０をシールワッシャ２の外周部の下面７に取付ける手段は任意であり、インサート成形法によって一体成形してもよく、あるいは接着剤で貼り付けることも可能である。 The material of the elastic sealing material 10 is, for example, an olefin-based elastomer, but is not limited thereto, and a general sealing material such as rubber can be used. Further, the means for attaching the elastic sealing material 10 to the lower surface 7 of the outer peripheral portion of the seal washer 2 is arbitrary, and may be integrally formed by an insert molding method, or may be attached with an adhesive.
　図３は第１の実施形態のシールワッシャ付きナットをボルト２０と組み合わせ、２枚の相手部材Ａ，Ｂの締結を行なった状態を示している。締結開始時にはシールワッシャ２の下方に突出している弾性シール材１０が先ず相手部材Ａの表面に接触するが、さらにボルト２０をナット本体１に捻じ込んで行くと弾性シール材１０は次第に圧縮されて行き、最終的には図５に示すように、シールワッシャ２の内周部の下面８が相手部材Ａとメタルタッチした状態となる。この締結状態においてボルト２０に軸力を与えておけば弛みが生ずることがなくなる。また弾性シール材１０はそれ以上圧縮されることもないため、弾性シール材１０が押し潰されるように変形することもなくなる。この結果、安定した止水機能を半永久的に維持することが可能となる。 FIG. 3 shows a state in which the nut with seal washer of the first embodiment is combined with the bolt 20 and the two mating members A and B are fastened. At the start of fastening, the elastic sealing material 10 projecting downward from the seal washer 2 first contacts the surface of the mating member A. When the bolt 20 is further screwed into the nut body 1, the elastic sealing material 10 is gradually compressed. Finally, as shown in FIG. 5, the lower surface 8 of the inner peripheral portion of the seal washer 2 is in a metal touch with the mating member A. If an axial force is applied to the bolt 20 in this fastened state, no loosening occurs. Further, since the elastic sealing material 10 is not further compressed, the elastic sealing material 10 is not deformed so as to be crushed. As a result, a stable water stop function can be maintained semipermanently.
　なお、シールワッシャ２の内周部の下面８の面積は、必要とされる締結軸力と、相手部材の強度に応じて決定される。また、外周部の下面７と内周部の下面８との段差は、必要とする弾性シール材１０の圧縮率に応じて決定される。 Note that the area of the lower surface 8 of the inner peripheral portion of the seal washer 2 is determined according to the required fastening axial force and the strength of the mating member. Further, the step between the lower surface 7 of the outer peripheral portion and the lower surface 8 of the inner peripheral portion is determined according to the required compressibility of the elastic sealing material 10.
　図４、図５は本発明の第２の実施形態を示す図である。この第２の実施形態では、ナット本体１がフランジナットである。この場合にはフランジ１１がシールワッシャ２の外周部まで延びているため、第１の実施形態に比べてシールワッシャ２の全面に均一に軸力を作用させることができ、外周部の弾性シール材１０をより確実に圧縮することができる利点がある。その他の点は、第１の実施形態と同様であるので、説明を省略する。 4 and 5 are diagrams showing a second embodiment of the present invention. In the second embodiment, the nut body 1 is a flange nut. In this case, since the flange 11 extends to the outer peripheral portion of the seal washer 2, an axial force can be applied uniformly to the entire surface of the seal washer 2 as compared with the first embodiment, and an elastic sealing material for the outer peripheral portion can be obtained. There is an advantage that 10 can be more reliably compressed. Since other points are the same as those of the first embodiment, description thereof is omitted.
　図６、図７は本発明の第３の実施形態を示す図である。この第３の実施形態では、ナット本体１が角型ナットであり、その側面に形成された凹部１２を利用して他の部材に固定することができる構造となっている。その他の点は、第１の実施形態と同様であるので、説明を省略する。 6 and 7 are views showing a third embodiment of the present invention. In the third embodiment, the nut body 1 is a square nut, and has a structure that can be fixed to another member by using a recess 12 formed on a side surface thereof. Since other points are the same as those of the first embodiment, description thereof is omitted.
　以上に説明したように、本発明のシールワッシャ付きナットは、締結完了状態においてはシールワッシャ２の内周部の下面８が相手部材とメタルタッチするため、従来のように弛みが生ずることがない。しかも外周部に設けられた弾性シール材１０にはそれ以上の圧縮荷重が作用することがないため、弾性シール材１０が押し潰されるように変形することもなくなり、止水機能が損なわれることもない利点がある。さらにナット本体１とシールワッシャ２とが一体化されているので、締結作業性を向上させることができる。 As described above, in the nut with a seal washer according to the present invention, the bottom surface 8 of the inner peripheral portion of the seal washer 2 makes a metal touch with the mating member when the fastening is completed. . Moreover, since no further compressive load acts on the elastic sealing material 10 provided on the outer peripheral portion, the elastic sealing material 10 will not be deformed so as to be crushed, and the water stop function may be impaired. There are no advantages. Furthermore, since the nut body 1 and the seal washer 2 are integrated, the fastening workability can be improved.
