しかしながら上記前者のブラケットでは、深絞り成形を用いているため深絞り金型のコストが嵩むという問題があり、しかもストッパー用弾性体を有する防振装置に用いるにはストッパー部を設ける必要があってさらにコストが嵩むという問題があった。   However, the former bracket has the problem of increasing the cost of the deep drawing mold because it uses deep drawing, and it is necessary to provide a stopper portion for use in a vibration isolator having an elastic body for stopper. Furthermore, there was a problem that the cost increased.

また、上記後者のブラケットでは、丸め成形と曲げ成形と打ち抜きと溶接とで形成していることから深絞り金型のコストはかからないものの、ストッパー用弾性体と対向するストッパー部が一枚だけであるため、ストッパー用弾性体の一方向の動きしか規制できないという問題があった。   In the latter bracket, since it is formed by rounding, bending, punching, and welding, the cost of the deep drawing mold is not incurred, but there is only one stopper portion facing the elastic body for stopper. For this reason, there has been a problem that only one direction of movement of the stopper elastic body can be restricted.

この発明は上記課題を有利に解決することを目的とするものであり、この発明の防振装置用ブラケットは、内筒と外筒との間に本体用弾性体を介装されてなる防振装置本体と、前記内筒に結合されたストッパー用弾性体とを有する防振装置に用いられるブラケットにおいて、板材を円筒状に丸め、その板材の互いに突き合わせた両端部を互いに溶接接合して形成され、前記外筒を圧入固定される筒状部と、互いに離間して平行に延在する二つの当接部および、それらの当接部に結合されてそれらの当接部の延在方向と平行に互いに反対方向へ延在する溝形の二本の脚部を有するように板材から形成され、それらの当接部のうち一方の当接部を前記筒状部の一端に溶接固定されるとともにそれらの当接部の間に前記ストッパー用弾性体を遊挿されるストッパー部と、を具えることを特徴とするものである。   An object of the present invention is to advantageously solve the above-mentioned problems, and a vibration isolator bracket according to the present invention includes a main body elastic body interposed between an inner cylinder and an outer cylinder. In a bracket used in a vibration isolator having an apparatus main body and an elastic body for a stopper coupled to the inner cylinder, a plate material is rounded into a cylindrical shape, and both ends of the plate material butted against each other are welded together. A cylindrical portion in which the outer cylinder is press-fitted and fixed, two abutting portions that are spaced apart and extend in parallel, and are coupled to the abutting portions and are parallel to the extending direction of the abutting portions. And two groove-shaped leg portions extending in opposite directions to each other, and one of the contact portions is fixed by welding to one end of the tubular portion. The stopper elastic body is loosely inserted between the contact parts. A stopper portion that is characterized in that it comprises a.

この発明の防振装置用ブラケットによれば、防振装置本体の外筒を圧入固定される筒状部が、板材を円筒状に丸め、その板材の互いに突き合わせた両端部を互いに溶接接合して形成され、また防振装置のストッパー用弾性体を遊挿されるストッパー部が、互いに離間して平行に延在する二つの当接部および、それらの当接部に結合されてそれらの当接部の延在方向と平行に互いに反対方向へ延在する溝形の二本の脚部を有するように板材から形成され、それらの当接部のうち一方の当接部を前記筒状部の一端に溶接固定されるから、このブラケットの製造に深絞り成形を用いないため金型のコストを削減することができ、しかもストッパー部が二つの当接部を有するので、ストッパー用弾性体の二方向の動きを規制することができる。   According to the bracket for a vibration isolator of the present invention, the cylindrical portion on which the outer cylinder of the vibration isolator body is press-fitted and fixed rounds the plate material into a cylindrical shape, and both end portions of the plate material that are butted against each other are welded to each other. The stopper part formed and loosely inserted into the stopper elastic body of the vibration isolator is connected to the two abutting parts which are spaced apart from each other and extend in parallel, and the abutting parts thereof. Formed from a plate material so as to have two groove-shaped leg portions extending in opposite directions in parallel to the extending direction of one of the contact portions. Since the die is not used for manufacturing this bracket, the cost of the mold can be reduced, and the stopper portion has two abutting portions. Can be controlled.

なお、この発明の防振装置用ブラケットにおいては、前記ストッパー部が、前記二つの当接部が互いに対向して位置するように板材を角筒状に曲げ、その板材の互いに突き合わせた端部同士を互いに溶接接合して形成されるとともに、前記板材の前記互いに突き合わせた端部が、前記一方の当接部に位置していると好ましい。前記一方の当接部は筒状部の一端部に溶接固定させるので、このようにすれば筒状部が当接部を補強することになり、当接部の板材の互いに突き合わせた端部同士の溶接の剥がれを防止することができる。   In the vibration isolator bracket of the present invention, the stopper portion is formed by bending the plate material into a rectangular tube shape so that the two contact portions are positioned to face each other, and the end portions of the plate material that are butted against each other It is preferable that the end portions of the plate members that are butted against each other are positioned at the one contact portion. Since the one abutting portion is welded and fixed to one end of the cylindrical portion, in this way, the cylindrical portion reinforces the abutting portion, and the end portions of the abutting portion of the plate material that are abutted to each other It is possible to prevent peeling of welding.

また、この発明の防振装置用ブラケットにおいては、前記ストッパー部の前記一方の当接部に、前記内筒と前記ストッパー用弾性体とを結合する結合部が貫通する孔が形成されていると好ましい。このようにすればその貫通孔の周囲で当接部にストッパー用弾性体が当接するので、当接部の板材の互いに突き合わせた端部同士の溶接の剥がれを防止することができる。   Further, in the vibration isolator bracket of the present invention, a hole through which a coupling portion that couples the inner cylinder and the stopper elastic body passes is formed in the one contact portion of the stopper portion. preferable. If it does in this way, since the elastic body for stoppers contacts the contact part around the through hole, it is possible to prevent peeling of the welded ends of the plate members of the contact part.

さらに、この発明の防振装置用ブラケットにおいては、前記筒状部の板材が、前記ストッパー部の板材よりも薄いものとされていると好ましい。筒状部は防振装置を介して力が加わることからストッパー部ほど強度が必要でない処、このようにすればより軽くかつより低コストでブラケットを製造することができる。   Furthermore, in the vibration isolator bracket of the present invention, it is preferable that the plate member of the cylindrical portion is thinner than the plate member of the stopper portion. Since a force is applied to the cylindrical portion via the vibration isolator, the bracket is not required to be as strong as the stopper portion. In this way, the bracket can be manufactured lighter and at a lower cost.

さらに、この発明の防振装置用ブラケットにおいては、前記筒状部から延在するステー部が、前記筒状部の前記板材の前記互いに突き合わせた両端部を覆う位置に溶接固定されていると好ましい。このようにすればステー部が筒状部の板材の突き合わせた両端部を補強することになり、筒状部の板材の互いに突き合わせた端部同士の溶接の剥がれを防止することができる。   Further, in the vibration isolator bracket of the present invention, it is preferable that the stay portion extending from the tubular portion is welded and fixed at a position covering the both end portions of the plate portion of the tubular portion that face each other. . If it does in this way, a stay part will reinforce the both ends which the board | plate material of the cylindrical part faced | matched, and it can prevent peeling of the welding of the edge parts which faced each other of the board | plate material of a cylindrical part.

The plate material of the cylindrical portion 2 is thinner than the plate material of the stopper portion 3.

一方、防振装置本体５は、図５に示すように、カップ状の内筒５ａと、その内筒５ａよりも大径でその内筒５ａに対し同芯にかつ軸線方向にずれて位置する外筒５ｂとの間に本体用弾性体としての逆カップ状の本体用ゴム５ｃを配置し、その本体用ゴム５ｃを内筒５ａと外筒５ｂとに加硫接着するとともに、内筒５ａに対し外筒５ｂ側にその内筒５ａと同芯に結合部としてのパイプ５ｄを配置し、そのパイプ５ｄの軸線方向の一端を内筒５ａに溶接接合し、パイプ５ｄの他端部の内周面に雌ねじを形成して構成されており、かかる防振装置本体５をこの実施例の防振装置用ブラケット１で支持する際には、図５（ｂ）に示すように、外筒５ｂを筒状部２内に圧入するとともに、パイプ５ｄの上記他端部をストッパー部３の貫通孔３ｅ内に遊挿して当接部３ａ，３ｂ間に位置させ、その一方、アーム部材６の、ストッパー用ゴム７で周囲を囲繞された基部６ａをストッパー部３の角筒内にその軸線方向に遊挿して当接部３ａ，３ｂ間に位置させ、そのアーム部材６の基部６ａに挿通したボルト５ｅをパイプ５ｄの上記他端部の雌ねじに螺着することにより、アーム部材６を防振装置本体５の内筒５ａに結合する。   On the other hand, as shown in FIG. 5, the vibration isolator main body 5 has a cup-shaped inner cylinder 5 a and a diameter larger than that of the inner cylinder 5 a and is positioned concentrically with respect to the inner cylinder 5 a and shifted in the axial direction. An inverted cup-shaped main body rubber 5c as an elastic body for the main body is disposed between the outer cylinder 5b, the main body rubber 5c is vulcanized and bonded to the inner cylinder 5a and the outer cylinder 5b, and is attached to the inner cylinder 5a. On the other hand, a pipe 5d as a coupling portion is arranged concentrically with the inner cylinder 5a on the outer cylinder 5b side, one end in the axial direction of the pipe 5d is welded to the inner cylinder 5a, and the inner circumference of the other end of the pipe 5d When the anti-vibration device body 5 is supported by the anti-vibration device bracket 1 of this embodiment, as shown in FIG. 5 (b), the outer cylinder 5b is formed. While press-fitting into the cylindrical portion 2, the other end of the pipe 5d is loosely inserted into the through hole 3e of the stopper portion 3. On the other hand, the base portion 6a of the arm member 6 surrounded by the stopper rubber 7 is loosely inserted into the rectangular tube of the stopper portion 3 in the axial direction thereof and contacted. The arm member 6 is positioned between the portions 3a and 3b, and the bolt 5e inserted through the base portion 6a of the arm member 6 is screwed to the female screw at the other end of the pipe 5d. It binds to 5a.

上述のようにして図４に示す如く防振装置本体５を支持したこの実施例の防振装置用ブラケット１は、二本の脚部３ｃ，３ｄを車体のエンジンルーム内の例えばサイドメンバーに取付けるとともに、ステー部４の先端部をそのエンジンルーム内の例えばインナパネルに取付けることで車体に搭載でき、そして防振装置本体５の内筒５ａに基部６ａを結合したアーム部材６の先端部をエンジンに取付けることで、エンジンを支持しつつエンジンから車体への振動伝達を防止することができる。   The anti-vibration device bracket 1 according to this embodiment, which supports the anti-vibration device main body 5 as described above, attaches the two legs 3c and 3d to, for example, a side member in the engine room of the vehicle body. At the same time, the tip of the arm member 6 can be mounted on the vehicle body by attaching the tip of the stay 4 to, for example, an inner panel in the engine room, and the tip of the arm member 6 having the base 6a coupled to the inner cylinder 5a of the vibration isolator main body 5 As a result, vibration transmission from the engine to the vehicle body can be prevented while supporting the engine.

従って、この実施例の防振装置用ブラケット１によれば、防振装置本体５の外筒５ｂを圧入固定される筒状部２が、板材を円筒状に丸め、その板材の互いに突き合わせた両端部２Ａ，２Ｂを互いに溶接接合して形成され、また防振装置のストッパー用弾性体７を遊挿されるストッパー部３が、互いに離間して平行に延在する二つの当接部３ａ，３ｂおよび、それらの当接部３ａ，３ｂに結合されてそれらの延在方向と平行に互いに反対方向へ延在する溝形の二本の脚部３ｃ，３ｄを有するように板材から形成され、それらの当接部３ａ，３ｂのうち一方の当接部３ａを筒状部２の一端に溶接固定されるから、このブラケット１の製造に深絞り成形を用いないため金型のコストを削減することができ、しかもストッパー部３が二つの当接部３ａ，３ｂを有するので、ストッパー用ゴム７の、防振装置本体５の内外筒５ａ，５ｂの軸線方向に沿う二方向の動きを規制することができ、またストッパー部３が二つの側壁部を有するので、ストッパー用ゴム７の、防振装置本体５の内外筒５ａ，５ｂの軸線方向と直角な二方向の動きも規制することができる。   Therefore, according to the vibration isolator bracket 1 of this embodiment, the cylindrical portion 2 into which the outer cylinder 5b of the vibration isolator main body 5 is press-fitted and fixed rounds the plate material into a cylindrical shape, and both ends of the plate material abut each other. The stopper portions 3 formed by welding the portions 2A, 2B to each other and loosely inserted into the stopper elastic body 7 of the vibration isolator are two abutting portions 3a, 3b that are spaced apart from each other and extend in parallel. Are formed from a plate material so as to have two groove-shaped legs 3c and 3d which are coupled to the abutting portions 3a and 3b and extend in opposite directions in parallel to the extending direction thereof. Since one of the contact portions 3a and 3b is fixed by welding to one end of the cylindrical portion 2, the manufacturing cost of the bracket 1 can be reduced because the deep drawing is not used. In addition, the stopper portion 3 has two contact portions 3a. 3b, the stopper rubber 7 can be restricted from moving in two directions along the axial direction of the inner and outer cylinders 5a, 5b of the vibration isolator body 5, and the stopper portion 3 has two side walls. The movement of the stopper rubber 7 in two directions perpendicular to the axial direction of the inner and outer cylinders 5a and 5b of the vibration isolator body 5 can also be restricted.

さらに、この実施例の防振装置用ブラケット１によれば、ストッパー部３が、二つの当接部３ａ，３ｂが互いに対向して位置するように板材を角筒状に曲げ、その板材の互いに突き合わせた端部同士を互いに溶接接合して形成されるとともに、その板材の互いに突き合わせた端部が、一方の当接部３ａに位置しており、その一方の当接部３ａは筒状部２の一端部に溶接固定させるので、筒状部２が当接部３ａを補強することになり、当接部３ａの板材の互いに突き合わせた端部同士の溶接の剥がれを防止することができる。   Further, according to the vibration isolator bracket 1 of this embodiment, the stopper portion 3 bends the plate material into a rectangular tube shape so that the two abutting portions 3a and 3b face each other, and the plate materials are mutually connected. The abutted end portions are formed by welding to each other, and the abutted end portions of the plate material are located at one abutting portion 3a, and the one abutting portion 3a is the cylindrical portion 2 Since the cylindrical portion 2 reinforces the abutting portion 3a, it is possible to prevent peeling of the welded end portions of the plate members of the abutting portion 3a.

また、この実施例の防振装置用ブラケット１によれば、ストッパー部３の一方の当接部３ａに、内筒５ａとストッパー用ゴム７とを結合するパイプ５ｄが貫通する貫通孔３ｅが形成されていることから、その貫通孔３ｅの周囲で当接部３ａにストッパー用ゴム７が当接するので、その貫通孔３ｅの周囲で当接力を均等に受け得て、当接部３ａの板材の互いに突き合わせた端部同士の溶接の剥がれを防止することができる。   In addition, according to the vibration isolator bracket 1 of this embodiment, the through hole 3e through which the pipe 5d connecting the inner cylinder 5a and the stopper rubber 7 passes is formed in one abutting portion 3a of the stopper portion 3. Therefore, the stopper rubber 7 comes into contact with the contact portion 3a around the through hole 3e, so that the contact force can be evenly received around the through hole 3e, and the plate of the contact portion 3a It is possible to prevent peeling of the welds between the end portions butted against each other.

さらに、筒状部２は防振装置を介して力が加わることからストッパー部３ほど強度が必要でない処、この実施例の防振装置用ブラケット１によれば、筒状部２の板材が、ストッパー部３の板材よりも薄いものとされているので、より軽くかつより低コストでブラケット１を製造することができる。   Furthermore, since force is applied to the cylindrical portion 2 through the vibration isolator, the strength of the stopper portion 3 is not required, and according to the vibration isolator bracket 1 of this embodiment, the plate material of the cylindrical portion 2 is Since the stopper 3 is thinner than the plate member, the bracket 1 can be manufactured lighter and at a lower cost.

さらに、この実施例の防振装置用ブラケット１によれば、筒状部２から延在するステー部４が、筒状部２の板材の互いに突き合わせた両端部２Ａ，２Ｂを覆う位置に溶接固定しているので、ステー部４が筒状部２の板材の突き合わせた両端部２Ａ，２Ｂを補強することになり、筒状部２の板材の互いに突き合わせた端部２Ａ，２Ｂ同士の溶接の剥がれを防止することができる。   Further, according to the vibration isolator bracket 1 of this embodiment, the stay portion 4 extending from the cylindrical portion 2 is welded and fixed at a position covering both end portions 2A and 2B of the plate portion of the cylindrical portion 2 which are abutted with each other. Therefore, the stay portion 4 reinforces both end portions 2A and 2B where the plate material of the cylindrical portion 2 is abutted, and the end portions 2A and 2B of the plate portion of the cylindrical portion 2 which are abutted with each other are peeled off. Can be prevented.

以上、図示例に基づき説明したが、この発明は上述の例に限られるものでなく、特許請求の範囲の記載範囲内で適宜変更し得るものであり、例えば防振装置本体５は、既知の液入り防振装置を構成するものでも良く、またストッパー部３は、角筒状の部材でなく二つの当接部３ａ，３ｂの一端部を連結部で繋いだコ字状の部材からなるものでも良い。   Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described examples, and can be appropriately changed within the scope of the claims. For example, the vibration isolator main body 5 is a known one. The stopper 3 may be a U-shaped member in which one end of the two abutting portions 3a and 3b is connected by a connecting portion instead of a rectangular tube-shaped member. But it ’s okay.

かくしてこの発明の防振装置用ブラケットによれば、防振装置本体の外筒を圧入固定される筒状部が、板材を円筒状に丸め、その板材の互いに突き合わせた両端部を互いに溶接接合して形成され、また防振装置のストッパー用弾性体を遊挿されるストッパー部が、互いに離間して平行に延在する二つの当接部および、それらの当接部に結合されてそれらの当接部の延在方向と平行に互いに反対方向へ延在する溝形の二本の脚部を有するように板材から形成され、それらの当接部のうち一方の当接部を前記筒状部の一端に溶接されるから、このブラケットの製造に深絞り成形を用いないため金型のコストを削減することができ、しかもストッパー部が二つの当接部を有するので、ストッパー用弾性体の二方向の動きを規制することができる。   Thus, according to the bracket for vibration isolator of the present invention, the cylindrical portion to which the outer cylinder of the vibration isolator main body is press-fitted and fixed rounds the plate material into a cylindrical shape, and both end portions of the plate material which are butted against each other are welded to each other. And a stopper part loosely inserted into the stopper elastic body of the vibration isolator is connected to the two abutting parts which are spaced apart from each other and extend in parallel, and to the abutting parts. Formed from a plate material so as to have two groove-shaped legs extending in opposite directions in parallel to the extending direction of the portion, and one of the abutting portions of the cylindrical portion is Since it is welded to one end, the cost of the mold can be reduced because deep drawing is not used to manufacture this bracket, and the stopper part has two abutting parts. Can be controlled.
