Description

【０００１】
【発明の属する技術分野】
本発明は、自動車に搭載されるラジエータの取付けに用いられるラジエータサポートに関する。
【０００２】
【従来の技術】
従来より、ラジエータを自動車に搭載する場合、ラジエータの上下両端部を弾性支持するラジエータサポートを介して取付けることにより、ラジエータがダイナミックダンパの質量体として機能するようにし、これにより車体に伝達される振動を低減するようにしている。このようなラジエータサポートとして、例えば特開平７−１８６７３８号公報や特開平８−１８３３５１号公報、特開平１０−１０９５５１号公報等に開示されているように、ゴム弾性体を主体としてリング状に形成された種々のものが知られている。
【０００３】
このラジエータサポートは、その軸方向が縦向きとなるようにして車体側の取付部に固定するとともに、ラジエータの上下両端にそれぞれ縦方向に突設された支持ピンをラジエータサポートの内孔に嵌合固定することにより取付けられる。これにより、ラジエータは、その上下両端部を適数個のラジエータサポートにより弾性支持された状態で車体上に搭載される。
【０００４】
【発明が解決しようとする課題】
ところで、ラジエータが搭載される自動車のエンジンルームには、ラジエータの他にもエンジンユニット等の非常に多数の機器類が収納配置されていることから、ラジエータの取付けスペースや取付け方法において設計上の制約を受け易い。そのため、上記のようにラジエータサポートを縦向きにして取付けることができない場合がある。
【０００５】
そこで、例えば、ラジエータの取付部に横向きの取付孔を設けておき、その取付孔に横向きに嵌挿したラジエータサポートによりラジエータの取付部を両側から狭持する状態でラジエータを車体に固定する取付方法が考えられる。このようにした場合、ラジエータサポートは、取付孔に嵌挿される筒状部と、筒状部の両端に設けられるフランジ部とを有する構造となる。
【０００６】
しかし、このような構造においては、両フランジ部をラジエータの取付孔よりも大きくしなければならないことから、筒状部を取付孔に嵌挿できるようにするためにはラジエータサポートを少なくとも二つに分割形成しなければならず、部品数の増大を招いて取付作業を煩雑化させるという難点がある。
【０００７】
また、特に筒状部と両フランジ部との連結部には、ラジエータの荷重や振動による大きな負荷が掛かることから、ラジエータサポートをゴム弾性体のみで形成することは強度不足となるためできず、補強用の金属部材が必要となる。この場合、ゴム弾性体と金属部材は、通常行われる加硫接着により容易に一体化することができるが、加硫接着を行うと、接着剤の塗布やゴム弾性体の金属部材との一体成形等、製作に手間がかかり高コストとなる。しかも、ラジエータサポートには、雨水や泥等が付着し易いことから金属部材の防錆処理が必要となるが、ゴム弾性体と一体となった金属部材には、例えばカチオン塗装やメッキ等の安価な防錆処理を施すことができず、加硫接着後に高価な防錆塗装を施さなければならないため、やはり高コストとなる。
【０００８】
本発明は上記実状に鑑みてなされたものであり、ラジエータの取付孔に嵌挿されて取付けられるラジエータサポートであって、取付作業を容易に行うことができ、製造コストの低減化を図ることが可能なラジエータサポート及びそのラジエータサポートの組付構造体を提供することを解決すべき課題とするものである。
【０００９】
【課題を解決するための手段、発明の作用及び効果】
上記課題を解決する請求項１に記載の発明に係るラジエータサポートは、ラジエータの取付孔に嵌挿される第１筒状基部と該第１筒状基部の一端から径方向外方に延出しその外側端面に開口する凹部をもつリング状の第１フランジ部と該第１フランジ部の前記凹部の外周部から径方向内方へ張り出して周方向に距離を隔てて設けられた複数の保持部とを有する第１ゴム部材と、前記第１フランジ部の前記凹部に非接着状態で収納されて前記保持部により外周部を保持されたリング板状の第１金属部材と、からなる第１分割部品と、前記第１筒状基部の内孔に嵌挿される第２筒状基部と該第２筒状基部の前記第１フランジ部と反対側の端部から径方向外方に延出するリング状の第２フランジ部とを有する第２金属部材と、前記第２筒状基部の外周に非接着状態で嵌合保持されて前記第２フランジ部と前記第１筒状基部との間に配置されるリング板状の第２ゴム部材と、からなる第２分割部品と、から構成されているという手段を採用している。
【００１０】
本発明のラジエータサポートは、第１分割部品と第２分割部品の二つの部品に分割形成されていることから、部品数の増大が最小限に抑えられている。そして、第１分割部品の第１筒状基部の内孔に第２分割部品の第２筒状基部を嵌挿して組付けることにより、ラジエータサポートの取付けを行うことができるので、その取付作業を容易に行うことが可能となる。
【００１１】
また、本発明のラジエータサポートは、第１分割部品の第１ゴム部材と第１金属部材、及び第２分割部品の第２ゴム部材と第２金属部材が、いずれの場合にも接着剤等を用いることなく非接着状態で一体的に組付けられている。そのため、加硫接着等の製作に手間がかかり高コストとなる手法を採用する必要がないので、製造コストの低減化が可能となる。さらに、第１金属部材及び第２金属部材は、第１ゴム部材及び第２ゴム部材と別体に形成されているので、それらと組付けられる前に、例えばカチオン塗装やメッキ等の安価な防錆処理を施すことができるため、より一層製造コストの低減化を図ることが可能となる。
【００１２】
そして、本発明のラジエータサポートは、第１フランジ部の凹部の外周部に、径方向内方へ張り出して凹部に収納された第１金属部材の外周端部を保持する複数の保持部が周方向に距離を隔てて設けられていることから、第１フランジ部の凹部に収納された第１金属部材を、接着手段を用いることなく確実に凹部に保持することができる。また、隣り合う二つの保持部の間には、径方向外方に広がった凹部の開口部が形成されているので、その大きく広がった開口部より第１金属部材を凹部へ容易に収納することができる。
【００１３】
なお、この保持部の形状や大きさは、凹部や第１金属部材との関係において適宜設定することができる。また、保持部の厚みは、１〜３ｍｍ程度にするのが好ましい。保持部の厚みが１ｍｍ未満であると、加硫成形時にゴムが廻り難くなるため、保持部の形成が困難になる。逆に、保持部の厚みが３ｍｍを上回ると、保持部の剛性が高くなるため、手作業で第１金属部材を凹部へ収納する場合に、その作業が困難になる。この保持部は、周方向に距離を隔てて複数のものを設けることができるが、保持部の保持力が周方向において均等になるようにするためには等間隔に配置するのが好ましい。また、隣り合う二つの保持部の間の部分、即ち、径方向外方に広がった凹部の開口部が軸対称となる位置或いはそれに近い位置にあるように保持部を配置するのが好ましい。このようにすれば、第１金属部材を凹部へ挿入する際の凹部の挿入口を大きくすることができるので、第１金属部材を凹部に容易に挿入することができる。
【００１４】
したがって、本発明のラジエータサポートによれば、その取付作業を容易に行うことができ、製造コストの大幅な低減化を図ることができる。
【００１５】
また、請求項２に記載の発明に係るラジエータサポートは、請求項１に記載の発明において、前記第１金属部材は、一つの前記保持部を弾性変形させて前記凹部の開口が径方向に開く状態にし、その径方向に開いた前記凹部の開口部より径方向に挿入されて前記凹部に収納されているという手段を採用している。この手段によれば、特別な治具等を用いることなく手作業で、第１金属部材を凹部に容易に収納することができる。これにより、製造コストのより一層の低減化が可能となる。
【００１６】
また、請求項３記載の発明に係るラジエータサポートは、請求項１又は２に記載の発明において、前記第１金属部材には、前記第１金属部材には、前記第２筒状基部の内孔に挿通される取付ボルトと螺合するナットが固着されているという手段を採用している。この手段によれば、ラジエータサポートを取付ける際に用いられる締結部材としてのナットが第１金属部材に予め固着されているため、取付ボルトの締結時にナットの位置合わせ等が不要になり、ラジエータサポートの取付作業が一段と容易になる。
【００１７】
また、請求項４に記載の発明に係るラジエータサポートは、請求項１〜３に記載の発明において、前記第２金属部材の前記第２フランジ部には、車体フレームの取付部に係止される係止部が設けられているという手段を採用している。
【００１８】
上記課題を解決する請求項５に記載の発明に係るラジエータサポートの組付構造体は、請求項１〜４の何れかに記載のラジエータサポートが、前記ラジエータの前記取付孔に前記第１筒状基部を嵌挿して前記第１分割部品を前記ラジエータに仮止めすると共に、前記第２分割部品を車体フレームに仮止めし、該車体フレームに仮止めされた前記第２分割部品の前記第２筒状基部に対して、前記ラジエータに仮止めされた前記第１分割部品の前記第１筒状基部の内孔を嵌合することにより、前記第１分割部品と前記第２分割部品とが組付けられていることを特徴としている。
【００１９】
また、請求項６に記載の発明に係るラジエータサポートの組付構造体は、前記第２分割部品は、前記第２フランジ部に設けられた前記係止部を前記車体フレームに係止することにより仮止めされることを特徴としている。
【００２０】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づき説明する。
【００２１】
図１は本実施形態に係るラジエータサポートの軸方向に沿う断面図であり、図２はそのラジエータサポートの第１分割部品の断面図であり、図３はその第１分割部品の正面図であり、図４はそのラジエータサポートの第２分割部品の断面図であり、図５はその第２分割部品の正面図である。
【００２２】
本実施形態のラジエータサポートは、後に詳述する図６に示すラジエータの取付けに用いられるものであって、図１に示すように、第１ゴム部材１１及び第１金属部材１５からなる第１分割部品１と、第２金属部材２１及び第２ゴム部材２５からなる第２分割部品２とで構成されている。
【００２３】
第１分割部品１は、図２及び図３に示すように、ゴム弾性体により略円筒状に形成された第１ゴム部材１１と、鉄系金属により円盤状に形成された第１金属部材１５とからなる。第１ゴム部材１１は、厚肉の円筒状に形成された第１筒状基部１２と、第１筒状基部１２の一端から径方向外方に延出するリング状の第１フランジ部１３とを有する。第１筒状基部１２の外周面の略中央には、周方向に延びる凹溝１２ａが設けられている。また、第１筒状基部１２の内周面は、中央部から両端に向かって次第に大径となるようにテーパ状に形成されている。
【００２４】
第１フランジ部１３の外側端面には、その外側端面に開口し第１金属部材１５が収納される凹部１３ａが設けられている。この凹部１３ａは、第１金属部材１５の金属板１５ａの形状と符合する大きさの薄いリング板形状に形成されている。そして、第１フランジ部１３の凹部１３ａの外周部には、周方向において等距離を隔てた３箇所に径方向内方へ張り出すようにして形成された３個の保持部１３ｂ、…、１３ｂが設けられている。各保持部１３ｂ、…、１３ｂは、凹部１３ａの外周長の１／６強となる長さに形成されており、隣り合う二つの保持部１３ｂ、１３ｂの間には、凹部１３ａの外周長の１／６弱の幅で径方向外方に広がった凹部１３ａの開口部が形成されている。この場合、３箇所に形成される径方向外方に広がった凹部１３ａの開口部の内の隣り合う２箇所の開口部が軸対称位置に近い位置にあるようになっている。各保持部１３ｂ、…、１３ｂの厚みは１．８ｍｍとされている。
【００２５】
第１金属部材１５は、薄いリング板状に形成された金属板１５ａと、金属板１５ａの一方面に同軸状に固着されたナット１５ｂとからなる。金属板１５ａは、第１筒状基部１２の内径よりも少し小さく、ナット１５ｂのねじ穴と略同じ大きさの内径を有する。この第１金属部材１５は、金属板１５ａの全体が第１フランジ部１３の凹部１３ａに収納されており、凹部１３ａの外周部に設けられた３個の保持部１３ｂ、…、１３ｂで金属板１５ａの外周端部が係合保持されている。
【００２６】
なお、第１金属部材１５の金属板１５ａの凹部１３ａへの収納は、簡単な手作業で行うことができる。即ち、一つの保持部１３ｂを手で起こすように弾性変形させて凹部１３ａの開口が径方向に開く状態にし、その弾性変形させた保持部１３ｂの両側の保持部１３ｂ、１３ｂとの間に形成される径方向に開いた開口部より第１金属部材１５の金属板１５ａを径方向にスライドさせて凹部１３ａに挿入した後、手を保持部１３ｂから離せばよい。これにより、その保持部１３ｂが弾性復帰して、凹部１３ａに収納された金属板１５ａの外周端部に係合し、凹部１３ａに収納された金属板１５ａが凹部１３ａから離脱しないように保持部１３ｂ、…、１３ｂにより保持される。
【００２７】
このようにして凹部１３ａに金属板１５ａが収納された第１金属部材１５は、加硫接着の手法や接着剤等を採用することなく非接着状態で第１ゴム部材１１に組付けられている。なお、この第１金属部材１５は、第１ゴム部材１１と一体化される前に、例えばカチオン塗装やメッキ等の安価な防錆処理が施されている。
【００２８】
一方、第２分割部品２は、図４及び図５に示すように、鉄系金属により形成された第２金属部材２１と、ゴム弾性体によりリング板状に形成された第２ゴム部材２５とからなる。第２金属部材２１は、第１筒状基部１２の内孔に嵌挿される第２筒状基部２２と、第２筒状基部２２の第１フランジ部１３と反対側の端部から径方向外方に延出するリング状の第２フランジ部２３とを有する。第２筒状基部２２は、略一定の内外径を有する円筒状に形成されており、その外径は第１筒状基部１２の最小内径と略同じである。
【００２９】
第２フランジ部２３は、第２筒状基部２２と同じ金属材料にプレス加工を施して一体成形することにより形成されている。この第２フランジ部２３は、第１金属部材１５の金属板１５ａの外径と略同じ外径を有する。この第２フランジ部２３の外周部の一部分には、弓形状の切欠き部が形成されており、その切欠き部の中央には、径方向外方に延出した後、軸方向外方に屈曲し更に径方向内方に屈曲して断面コの字形状に形成された係止部２３ａが設けられている。
【００３０】
なお、この第２金属部材２１は、第２ゴム部材２５と一体化される前に、例えばカチオン塗装やメッキ等の安価な防錆処理が施されている。
【００３１】
第２ゴム部材２５は、第１ゴム部材１１と同じゴム弾性体によりリング板状に形成されている。この第２ゴム部材２５は、第２筒状基部２２の外径と略同じ内径を有し、第１ゴム部材１１の第１フランジ部１３の外径よりも少し小さい外径を有する。この第２ゴム部材２５は、第２筒状基部２２の外周面の第２フランジ部２３側端部に非接着状態で嵌合保持されている。これにより、第２ゴム部材２５は、第２フランジ部２３と第１筒状基部１２との間に両者と接触する状態に配置される（図１参照）。
【００３２】
以上のように構成された本実施形態のラジエータサポートは、図６に示すような四角板状のラジエータ３を車体フレームに取付ける際に用いられる。このラジエータ３の上下両端のそれぞれ２箇所には、上下方向にそれぞれ突出する合計４個の取付部３１、…、３１が設けられており、各取付部３１、…、３１には、厚さ方向（横方向）に貫通する取付孔３２、…、３２が設けられている。このラジエータ３は、図７に示すように、上記ラジエータサポート及び取付ボルト４１を用いて車体フレーム４に取付けられる。
【００３３】
この場合、先ず、ラジエータ３の取付孔３２に第１筒状基部１２を嵌挿して第１分割部品１をラジエータ３に仮止めする。次に、車体フレーム４の取付部の所定部位に第２フランジ部２３に設けられた係止部２３ａを係止して、第２分割部品２を車体フレーム４に仮止めする。このとき、車体フレーム４に設けられた挿通孔４ａと第２筒状基部２２の内孔が一致するように位置合わせしておく。
【００３４】
次に、車体フレーム４に仮止めされた第２分割部品２の第２筒状基部２２に、ラジエータ３に仮止めされた第１分割部品１の第１筒状基部１２の内孔を嵌合して、第１分割部品１と第２分割部品２とを組付ける。これにより、ラジエータ３の取付部３１は、第１ゴム部材１１の第１フランジ部１３と第２ゴム部材２５とにより挟まれた状態となる。この状態で、車体フレーム４の挿通孔４ａから第２筒状基部２２の内孔に取付ボルト４１を挿通し、取付ボルト４１の先端部を第１金属部材１５のナット１５ｂと螺合させて締結する。これにより、図７に示すように、ラジエータ３が車体フレーム４にラジエータサポートで弾性支持された状態に取付けられ、取付作業が終了する。
【００３５】
以上のように、本実施形態のラジエータサポートは、第１分割部品１の第１ゴム部材１１と第１金属部材１５、及び第２分割部品２の第２金属部材２１と第２ゴム部材２５が、いずれの場合にも接着剤等を用いることなく非接着状態で一体的に組付けられている。そのため、加硫接着等の製作に手間がかかり高コストとなる手法を採用する必要がないので、製造コストを低減化することができる。
【００３６】
また、本実施形態のラジエータサポートは、第１金属部材１５及び第２金属部材２１が、第１ゴム部材１１又は第２ゴム部材２５と接着されずに別体に形成されているため、それらと組付けられる前に、カチオン塗装やメッキ等の安価な防錆処理を施すことができるため、より一層製造コストの低減化を図ることができる。
【００３７】
さらに、第１分割部品１においては、第１フランジ部１３の凹部１３ａの外周部に３個の保持部１３ｂ、…、１３ｂが等間隔に設けられているため、凹部１３ａに収納された第１金属部材１５を、接着手段を用いることなく確実に保持することができる。
【００３８】
また、３個の保持部１３ｂ、…、１３ｂは、周方向に等距離を隔てて設けられていることから、隣り合う二つの保持部１３ｂ、１３ｂの間には、径方向外方に広がった凹部１３ａの開口部が形成されているので、その径方向外方に広がった開口部より第１金属部材１５を凹部１３ａへ容易に収納することができる。
【００３９】
本実施形態の場合には、保持部１３ｂ、…、１３ｂが３箇所に設けられていることから、一つの保持部１３ｂを手で弾性変形させて凹部１３ａの開口が径方向に開く状態にし、その径方向に開いた開口部より第１金属部材１５を径方向にスライドさせて挿入するようにしているため、特別な治具等を用いることなく手作業で、第１金属部材１５を凹部１３ａに容易に収納することができる。
【００４０】
なお、保持部１３ｂを４箇所以上に設けた場合には、二つ以上の保持部１３ｂを弾性変形させなければならないので作業が煩雑になる。また、保持部１３ｂを２箇所に設けた場合には、凹部１３ａに収納された第１金属部材１５を確実に保持できなくなる可能性がある。よって、本実施形態のように、３個の保持部１３ｂ、…、１３ｂを３箇所に設けるのが最適と考えられる。
【００４１】
また、第１金属部材１５には、ラジエータサポートを取付ける際に、第２筒状基部２２の内孔に挿通される取付ボルト４１と螺合するナット１５ｂが固着されているので、取付ボルト４１の締結時にナット１５ｂの位置合わせ等が不要になるため、ラジエータサポートの取付作業が一段と容易になる。
【００４２】
なお、図８及び図９に示すように、第１ゴム部材１１において、第１フランジ部１３の凹部１３ａの外周部に設けられる保持部１３ｂ、…、１３ｂの形状や大きさ等を適宜変更することができる。この保持部１３ｂ、…、１３ｂは、周方向に延びる幅広の円弧形状に形成されており、３個のものが周方向に等距離を隔てて３箇所に設けられている。この保持部１３ｂは、上記実施形態のものより大きく形成されていることにより、凹部１３ａに収納される第１金属部材（図示せず）の保持力を高めるようにしている。

BACKGROUND OF THE INVENTION
The present invention relates to a radiator support used for mounting a radiator mounted on an automobile.
[0002]
[Prior art]
Conventionally, when a radiator is mounted on an automobile, the radiator is functioned as a mass body of a dynamic damper by attaching it via a radiator support that elastically supports both upper and lower ends of the radiator. Is trying to reduce. As such a radiator support, for example, as disclosed in JP-A-7-18638, JP-A-8-183351, JP-A-10-109551, etc., a rubber elastic body is mainly formed in a ring shape. Various types are known.
[0003]
This radiator support is fixed to the mounting part on the vehicle body side so that its axial direction is vertical, and the support pins protruding vertically at both the upper and lower ends of the radiator are fitted into the inner holes of the radiator support. Installed by fixing. As a result, the radiator is mounted on the vehicle body with its upper and lower ends elastically supported by an appropriate number of radiator supports.
[0004]
[Problems to be solved by the invention]
By the way, in the engine room of a car in which a radiator is mounted, a large number of devices such as an engine unit are accommodated in addition to the radiator. Therefore, there are design restrictions in the installation space and the installation method of the radiator. It is easy to receive. Therefore, there are cases where the radiator support cannot be mounted vertically as described above.
[0005]
Therefore, for example, a mounting method for fixing the radiator to the vehicle body in a state where the mounting portion of the radiator is provided with a horizontal mounting hole, and the mounting portion of the radiator is sandwiched from both sides by a radiator support that is horizontally inserted into the mounting hole. Can be considered. In this case, the radiator support has a structure having a cylindrical portion that is fitted into the mounting hole and flange portions that are provided at both ends of the cylindrical portion.
[0006]
However, in such a structure, since both flange portions must be larger than the mounting holes of the radiator, in order to be able to fit the tubular portion into the mounting holes, at least two radiator supports are used. There is a problem in that it must be divided and formed, which increases the number of parts and complicates the installation work.
[0007]
In addition, since a large load is applied to the connecting portion between the tubular portion and both flange portions due to the load and vibration of the radiator, it is not possible to form the radiator support with only a rubber elastic body because the strength is insufficient. A metal member for reinforcement is required. In this case, the rubber elastic body and the metal member can be easily integrated by the usual vulcanization adhesion, but if vulcanization adhesion is performed, the adhesive is applied or the rubber elastic body is integrally formed with the metal member. Such as, it takes time to produce, and it becomes high cost. In addition, since the radiator support is likely to adhere to rainwater, mud, etc., it is necessary to prevent the metal member from being rusted. However, the metal member integrated with the rubber elastic body has a low cost such as cationic coating or plating. Therefore, it is difficult to apply a rust-proofing treatment, and an expensive rust-proofing coating must be applied after vulcanization and adhesion, resulting in high costs.
[0008]
The present invention has been made in view of the above-described circumstances, and is a radiator support that is fitted into and attached to a radiator mounting hole, can be easily mounted, and the manufacturing cost can be reduced. It is an object of the present invention to provide a possible radiator support and an assembly structure of the radiator support .
[0009]
[Means for solving the problems, actions and effects of the invention]
The radiator support according to the first aspect of the present invention that solves the above problem includes a first cylindrical base portion that is fitted into a mounting hole of the radiator and an outer side that extends radially outward from one end of the first cylindrical base portion. A ring-shaped first flange portion having a recess opening in the end surface, and a plurality of holding portions provided radially outward from the outer periphery of the recess of the first flange portion and spaced apart in the circumferential direction a first rubber member having a ring-shaped first metal member and the outer peripheral portion held by the holding unit is housed in a non-adhered state to said recess of said first flange portion, a first divided part consisting of A ring-like shape extending radially outward from a second cylindrical base portion inserted into the inner hole of the first cylindrical base portion and an end portion of the second cylindrical base portion opposite to the first flange portion. A second metal member having a second flange portion and an outside of the second cylindrical base portion It is composed of a ring-shaped second rubber member disposed between the is fitted and held the second flange portion and the first tubular base portion in a non-adhesion state, and the second divided part consisting of, a It adopts the means of being.
[0010]
Since the radiator support of the present invention is divided into two parts, the first divided part and the second divided part, an increase in the number of parts is minimized. And by attaching and assembling the second cylindrical base part of the second divided part into the inner hole of the first cylindrical base part of the first divided part, the radiator support can be attached. It can be easily performed.
[0011]
In the radiator support of the present invention, the first rubber member and the first metal member of the first divided part, and the second rubber member and the second metal member of the second divided part are each provided with an adhesive or the like. They are assembled together in a non-adhered state without using them. For this reason, it is not necessary to employ a method that requires time and cost for production such as vulcanization adhesion, and thus the production cost can be reduced. Furthermore, since the first metal member and the second metal member are formed separately from the first rubber member and the second rubber member, before assembling with the first rubber member and the second rubber member, for example, inexpensive protection such as cationic coating or plating is performed. Since the rust treatment can be performed, the manufacturing cost can be further reduced.
[0012]
In the radiator support according to the present invention, a plurality of holding portions that protrude radially inward and hold the outer peripheral end portion of the first metal member housed in the concave portion are circumferentially provided on the outer peripheral portion of the concave portion of the first flange portion.

As described above, the radiator support of the present embodiment includes the first rubber member 11 and the first metal member 15 of the first divided component 1, and the second metal member 21 and the second rubber member 25 of the second divided component 2. In any case, they are integrally assembled in a non-adhered state without using an adhesive or the like. For this reason, it is not necessary to employ a method that requires labor and high cost for production such as vulcanization adhesion, and thus the production cost can be reduced.
[0036]
Moreover, since the 1st metal member 15 and the 2nd metal member 21 are formed in the radiator support of this embodiment separately from the 1st rubber member 11 or the 2nd rubber member 25, they are not attached to them. Since inexpensive rust prevention treatment such as cationic coating or plating can be performed before assembly, the manufacturing cost can be further reduced.
[0037]
Further, in the first divided component 1, since the three holding portions 13b,... , 13b are provided at equal intervals on the outer peripheral portion of the concave portion 13a of the first flange portion 13, the first portion housed in the concave portion 13a.

Since the first metal member 15 is inserted by sliding in the radial direction from the opening opened in the radial direction, the first metal member 15 can be manually inserted without using a special jig or the like. Can be easily stored.
[0040]
In addition, when the holding parts 13b are provided at four or more places, the work becomes complicated because two or more holding parts 13b must be elastically deformed. Moreover, when the holding | maintenance part 13b is provided in two places, there exists a possibility that the 1st metal member 15 accommodated in the recessed part 13a cannot be hold | maintained reliably. Therefore, it is considered optimal to provide the three holding portions 13b,... , 13b at three locations as in this embodiment.
[0041]
Further, when attaching the radiator support to the first metal member 15, the nut 15 b that is screwed with the mounting bolt 41 inserted into the inner hole of the second cylindrical base portion 22 is fixed. Since it is not necessary to align the nut 15b at the time of fastening, the radiator support can be attached more easily.
[0042]
As shown in FIGS. 8 and 9, in the first rubber member 11, the shape and size of the holding portions 13b,... , 13b provided on the outer peripheral portion of the concave portion 13a of the first flange portion 13 are appropriately changed. be able to.
