Description

本発明は、防振装置を非振動部材に取り付けるための防振装置用ブラケットに関する。   The present invention relates to a vibration isolator bracket for attaching a vibration isolator to a non-vibrating member.

自動車等のエンジンと車体との間に介設される防振装置（エンジンマウント）は、ブラケットを介して非振動部材である車体に取り付けられる。
防振装置用ブラケットとしては、筒状部材と、筒状部材の開口端部に接合されたストッパ部材と、ストッパ部材に接合されたステーと、筒状部材の外周面に接合された取付部材と、を備えているものがある（例えば、特許文献１参照）。 A vibration isolator (engine mount) interposed between an engine such as an automobile and a vehicle body is attached to a vehicle body that is a non-vibrating member via a bracket.
As the vibration isolator bracket, a tubular member, a stopper member joined to the opening end of the tubular member, a stay joined to the stopper member, and an attachment member joined to the outer peripheral surface of the tubular member, (For example, refer to Patent Document 1).

前記したブラケットでは、筒状部材に防振装置の下端部が嵌め込まれ、ステーおよび取付部材が車体に取り付けられる。さらに、防振装置の上端部にエンジンから延ばされた振動側ブラケットが取り付けられることで、エンジンと車体との間に防振装置が介設される。   In the bracket described above, the lower end portion of the vibration isolator is fitted into the cylindrical member, and the stay and the attachment member are attached to the vehicle body. Further, the vibration-side bracket extended from the engine is attached to the upper end of the vibration isolator, so that the vibration isolator is interposed between the engine and the vehicle body.

ストッパ部材は、振動側ブラケットに対して上下方向に対向している。防振装置に圧縮方向の入力が加わったときに、振動側ブラケットがストッパ部材に当接することで、防振装置の変位量（防振側ブラケットの移動量）が規制されている。   The stopper member faces the vibration side bracket in the vertical direction. When an input in the compression direction is applied to the vibration isolator, the vibration side bracket abuts against the stopper member, so that the displacement amount of the vibration isolator (the amount of movement of the vibration isolation side bracket) is regulated.

前記した従来のブラケットでは、ステーおよびストッパ部材がそれぞれ筒状部材に溶接されているため、ステーおよびストッパ部材の強度を確保するのが難しいという問題がある。また、従来のブラケットは、多数の部品を溶接することで構成されているため、溶接長さが大きくなり、製造コストが高くなるという問題がある。   In the above-described conventional bracket, the stay and the stopper member are welded to the cylindrical member, respectively, so that it is difficult to ensure the strength of the stay and the stopper member. Moreover, since the conventional bracket is comprised by welding many components, there exists a problem that welding length becomes large and manufacturing cost becomes high.

本発明は、前記した問題を解決し、ステーおよびストッパ部の強度を高めるとともに、溶接長さを小さくすることができ、組立工数および部品点数を少なくし、軽量化および製造コストを低減することができる防振装置用ブラケットを提供することを目的とする。   The present invention solves the above-described problems, increases the strength of the stay and the stopper portion, reduces the welding length, reduces the number of assembly steps and the number of parts, and reduces the weight and manufacturing cost. An object of the present invention is to provide a bracket for an anti-vibration device.

前記課題を解決するため、本発明は、振動部材と非振動部材との間に介設される防振装置用ブラケットである。前記防振装置用ブラケットは、防振装置の下端部が嵌め込まれる筒状部材と、前記筒状部材の上側開口端部に接合されている第一取付部材と、前記筒状部材の外周面または下側開口端部に接合され、前記非振動部材に取り付けられる第二取付部材と、を備えている。前記防振装置の上端部には、前記振動部材から延ばされた振動側ブラケットが取り付けられている。前記第一取付部材には、前記非振動部材に取り付けられるステーと、前記振動側ブラケットに対して上下方向に対向するストッパ部と、が形成されている。   In order to solve the above problems, the present invention is a vibration isolator bracket interposed between a vibration member and a non-vibration member. The vibration isolator bracket includes a cylindrical member into which a lower end of the vibration isolator is fitted, a first attachment member joined to an upper opening end of the cylindrical member, and an outer peripheral surface of the cylindrical member or A second attachment member joined to the lower opening end and attached to the non-vibrating member. A vibration-side bracket extended from the vibration member is attached to the upper end portion of the vibration isolator. The first attachment member is formed with a stay attached to the non-vibrating member and a stopper portion facing the vibration side bracket in the vertical direction.

この構成では、ステーおよびストッパ部が第一取付部材に一体に形成されているため、ステーおよびストッパ部の強度を高めることができる。そして、ステーおよびストッパ部を一体に形成することで、部品点数が少なくなるため、ブラケットの各部品を接合するときの溶接長さを小さくすることができる。   In this configuration, since the stay and the stopper portion are formed integrally with the first mounting member, the strength of the stay and the stopper portion can be increased. Since the stay and the stopper portion are integrally formed, the number of parts is reduced, so that the welding length when joining the parts of the bracket can be reduced.

前記した防振装置用ブラケットにおいて、前記第一取付部材の一端部に前記ステーを突設するとともに、他端部に前記ストッパ部を形成し、前記第一取付部材の一端部および他端部を前記筒状部材の上側開口端部に接合することが望ましい。
このように、第一取付部材をステー側およびストッパ部側の二箇所で筒状部材に接合することで、第一取付部材が筒状部材に安定して支持されるため、ステーおよびストッパ部の強度を高めることができる。 In the vibration isolator bracket described above, the stay is projected from one end of the first mounting member, the stopper is formed at the other end, and the one end and the other end of the first mounting member are formed. It is desirable to join to the upper opening end of the cylindrical member.
Thus, since the first mounting member is stably supported by the cylindrical member by joining the first mounting member to the cylindrical member at two locations on the stay side and the stopper portion side, the stay and the stopper portion Strength can be increased.

前記した防振装置用ブラケットにおいて、前記筒状部材を板状部材の長手方向の縁部同士を接合して形成した場合には、筒状部材を簡単に製造することができる。   In the above-described vibration isolator bracket, when the cylindrical member is formed by joining the edges in the longitudinal direction of the plate member, the cylindrical member can be easily manufactured.

前記した防振用ブラケットにおいて、前記第二取付部材を二つの脚部を有する門形に形成し、前記第二取付部材の前記両脚部の内側面を前記筒状部材の外周面に接合した場合には、非振動部材に対するブラケットの安定性を高めることができる。   In the above-described vibration-proof bracket, when the second mounting member is formed in a gate shape having two leg portions, and the inner side surfaces of the both leg portions of the second mounting member are joined to the outer peripheral surface of the cylindrical member In addition, the stability of the bracket with respect to the non-vibrating member can be enhanced.

本発明の防振装置用ブラケットでは、ステーおよびストッパ部を一体に形成することで、ステーおよびストッパ部の強度を高めるとともに、部品点数を少なくすることができ、溶接長さを小さくすることができる。ひいては、防振装置用ブラケットの組立工数および部品点数を少なくし、防振装置用ブラケットを軽量化するとともに、防振装置用ブラケットの製造コストを低減することができる。   In the vibration isolator bracket of the present invention, by integrally forming the stay and the stopper portion, the strength of the stay and the stopper portion can be increased, the number of parts can be reduced, and the welding length can be reduced. . As a result, the number of assembly steps and the number of parts of the vibration isolator bracket can be reduced, the weight of the vibration isolator bracket can be reduced, and the manufacturing cost of the vibration isolator bracket can be reduced.

なお、振動部材とは、振動の発生源（例えば、エンジンやモータ等）のことである。また、非振動部材とは、振動部材の振動を伝えたくない部材（例えば、車体等）のことである。 The vibration isolator 1 is an anti-vibration support for an engine 2 such as an automobile (“vibrating member” in claims) on a vehicle body 3 (“non-vibrating member” in claims).
The vibration member is a vibration generation source (for example, an engine or a motor). The non-vibrating member is a member (for example, a vehicle body or the like) that does not want to transmit the vibration of the vibrating member.

防振装置１は、液体封入式のエンジンマウントである。防振装置１は、略円錐台形状に形成されたゴム製の弾性部材であるインシュレータ１ａを備えている。
また、防振装置１は、インシュレータ１ａの上端部にインサート成形された金属製の取付金具１ｂと、インシュレータ１ａの下端部が取り付けられた金属製の円筒金具１ｃと、を備えている。インシュレータ１ａの下端部は、円筒金具１ｃの内周面に加硫接着されている。 The vibration isolator 1 is a liquid-filled engine mount. The vibration isolator 1 includes an insulator 1a which is a rubber elastic member formed in a substantially truncated cone shape.
Further, the vibration isolator 1 includes a metal mounting bracket 1b that is insert-molded at the upper end of the insulator 1a, and a metal cylindrical bracket 1c to which the lower end of the insulator 1a is mounted. The lower end portion of the insulator 1a is vulcanized and bonded to the inner peripheral surface of the cylindrical metal fitting 1c.

防振装置１の取付金具１ｂの上端面には、エンジン２から延ばされた振動側ブラケット２ａが取り付けられる。また、防振装置１の下端部の円筒金具１ｃは、ブラケット１０を介して車体３に取り付けられる。このようにして、防振装置１は、エンジン２と車体３との間に介設される。   A vibration side bracket 2 a extending from the engine 2 is attached to the upper end surface of the mounting bracket 1 b of the vibration isolator 1. Further, the cylindrical metal fitting 1 c at the lower end of the vibration isolator 1 is attached to the vehicle body 3 via the bracket 10. In this way, the vibration isolator 1 is interposed between the engine 2 and the vehicle body 3.

ブラケット１０は、図１（ａ）および（ｂ）に示すように、円筒状の筒状部材２０と、筒状部材２０の上側開口端部２０ａ（図２参照）に接合された第一取付部材３０と、筒状部材２０の外周面に接合された第二取付部材４０と、を備えている。
本実施形態のブラケット１０は、筒状部材２０、第一取付部材３０および第二取付部材４０の三つの金属製の部品を接合することで構成されている（図３参照）。 As shown in FIGS. 1A and 1B, the bracket 10 includes a cylindrical tubular member 20 and a first mounting member joined to the upper opening end 20a (see FIG. 2) of the tubular member 20. 30 and a second mounting member 40 joined to the outer peripheral surface of the cylindrical member 20.
The bracket 10 of the present embodiment is configured by joining three metal parts, a cylindrical member 20, a first mounting member 30, and a second mounting member 40 (see FIG. 3).

筒状部材２０は、図３（ｃ）に示すように、上下に開口部が配置された円筒状の部材である。筒状部材２０には、図２に示すように、防振装置１の円筒金具１ｃが圧入される。
本実施形態の筒状部材２０は、図３（ｃ）に示すように、一枚の板状部材２１を円弧状に湾曲させ、板状部材２１の長手方向の縁部２１ａ，２１ａ同士を溶接することで、円筒状に形成されている。このように、一枚の板状部材２１を用いて筒状部材２０を簡単に形成することができる。
板状部材２１の接合部は、筒状部材２０の前側に配置されている。また、筒状部材２０の上側開口端部２０ａには、前後の二箇所に凹部２２，２２が形成されているため、筒状部材２０を軽量化するとともに、筒状部材２０と平板部３１との溶接長さを小さくすることができる。 As shown in FIG. 3C, the cylindrical member 20 is a cylindrical member in which openings are arranged on the upper and lower sides. As shown in FIG. 2, the cylindrical member 1 c of the vibration isolator 1 is press-fitted into the cylindrical member 20.
As shown in FIG. 3C, the tubular member 20 of the present embodiment bends one plate-like member 21 in an arc shape and welds the edges 21 a and 21 a in the longitudinal direction of the plate-like member 21 together. By doing so, it is formed in a cylindrical shape. Thus, the cylindrical member 20 can be easily formed using the single plate-like member 21.
The joint portion of the plate member 21 is disposed on the front side of the tubular member 20. Moreover, since the recessed part 22 and 22 are formed in two places before and behind at the upper opening end part 20a of the cylindrical member 20, while reducing the weight of the cylindrical member 20, the cylindrical member 20, the flat plate part 31, and The welding length can be reduced.

第一取付部材３０は、図３（ｂ）に示すように、平板状の平板部３１と、平板部３１の右縁部から右方に向けて突出したステー３２と、平板部３１の左縁部に形成されたストッパ部３３と、を備えている。   As shown in FIG. 3B, the first mounting member 30 includes a flat plate portion 31, a stay 32 that protrudes rightward from the right edge portion of the flat plate portion 31, and the left edge of the flat plate portion 31. And a stopper portion 33 formed on the portion.

平板部３１は、図５に示すように、筒状部材２０の上側開口端部２０ａに重ね合わされている。そして、平板部３１の右端部および左端部の下面と、筒状部材２０の上側開口端部２０ａの右端部および左端部とが溶接されている。   As shown in FIG. 5, the flat plate portion 31 is superimposed on the upper opening end 20 a of the tubular member 20. And the lower surface of the right end part and left end part of the flat plate part 31, and the right end part and left end part of the upper side opening end part 20a of the cylindrical member 20 are welded.

ステー３２は、図４に示すように、平板部３１の右縁部の中央部から右方に向けて突出しており、図５に示すように、ステー３２の先端部は上向きに傾斜している。
ステー３２の先端部には、図２に示すように、取付穴３２ａが形成されている。この取付穴３２ａにボルト（図示せず）を挿入し、ボルトを車体３から延ばされた非振動側ブラケット３ａに取り付けることで、ステー３２を車体３に取り付けることができる。 As shown in FIG. 4, the stay 32 protrudes rightward from the center of the right edge of the flat plate portion 31, and as shown in FIG. 5, the tip of the stay 32 is inclined upward. .
As shown in FIG. 2, a mounting hole 32 a is formed at the tip of the stay 32. The stay 32 can be attached to the vehicle body 3 by inserting a bolt (not shown) into the attachment hole 32 a and attaching the bolt to the non-vibration side bracket 3 a extended from the vehicle body 3.

平板部３１の中央部には、図４に示すように、円形の開口部３１ａが形成されている。この開口部３１ａは、筒状部材２０の内径よりも小さく形成されている。
平板部３１の開口部３１ａには、図２に示すように、筒状部材２０に取り付けられた防振装置１の上部が挿入される。平板部３１の開口部３１ａの内周面と、防振装置１の外周面との間には隙間が形成されている。 As shown in FIG. 4, a circular opening 31 a is formed at the center of the flat plate portion 31. The opening 31 a is formed smaller than the inner diameter of the cylindrical member 20.
As shown in FIG. 2, the upper portion of the vibration isolator 1 attached to the tubular member 20 is inserted into the opening 31 a of the flat plate portion 31. A gap is formed between the inner peripheral surface of the opening 31 a of the flat plate portion 31 and the outer peripheral surface of the vibration isolator 1.

ストッパ部３３は、開口部３１ａの開口縁部と平板部３１の左縁部との間の部位である。ストッパ部３３は、振動側ブラケット２ａの下方に配置され、振動側ブラケット２ａに対して上下方向（防振装置１の伸縮方向）に対向している。
なお、振動側ブラケット２ａにおいて、ストッパ部３３に対向する位置には、下方に向けて突出した弾性当接部２ｂが形成されている。 The stopper portion 33 is a portion between the opening edge portion of the opening portion 31 a and the left edge portion of the flat plate portion 31. The stopper portion 33 is disposed below the vibration side bracket 2a, and is opposed to the vibration side bracket 2a in the vertical direction (the expansion and contraction direction of the vibration isolator 1).
In the vibration side bracket 2a, an elastic contact portion 2b that protrudes downward is formed at a position facing the stopper portion 33.

ストッパ部３３の下面には、筒状部材２０の上側の開口端部２０ａが接合されている。また、図４に示すように、平板部３１の左縁部（ストッパ部３３の左端部）の中央部を円弧状に突出させ、平板部３１と筒状部材２０との接合箇所から平板部３１の左縁部までの間隔を広げることで、平板部３１と筒状部材２０との溶接領域を確保している。   An open end 20 a on the upper side of the tubular member 20 is joined to the lower surface of the stopper portion 33. Further, as shown in FIG. 4, the central portion of the left edge portion (left end portion of the stopper portion 33) of the flat plate portion 31 protrudes in an arc shape, and the flat plate portion 31 starts from the joint portion between the flat plate portion 31 and the tubular member 20. By expanding the distance to the left edge of the plate, a welding region between the flat plate portion 31 and the tubular member 20 is secured.

第二取付部材４０は、図３（ａ）に示すように、門形に形成されており、前後二つの脚部４１，４１と、両脚部４１，４１の上端部同士に架け渡された上桁部４２と、を備えている。
図１（ａ）に示すように、両脚部４１，４１の内側面は筒状部材２０の外周面に接合されており、上桁部４２は筒状部材２０の上方に配置されている。このように、第二取付部材４０は、第一取付部材３０および筒状部材２０を前後方向に跨いでいる。 As shown in FIG. 3A, the second mounting member 40 is formed in a gate shape, and is bridged between the two front and rear leg portions 41 and 41 and the upper end portions of the both leg portions 41 and 41. And a digit part 42.
As shown in FIG. 1A, the inner side surfaces of both leg portions 41, 41 are joined to the outer peripheral surface of the tubular member 20, and the upper girder portion 42 is disposed above the tubular member 20. Thus, the 2nd attachment member 40 straddles the 1st attachment member 30 and the cylindrical member 20 in the front-back direction.

脚部４１の下部には、長方形の溶接用開口部４１ａが開口している。図１（ｂ）に示すように、脚部４１を筒状部材２０の外周面に重ね合わせると、筒状部材２０の外周面が溶接用開口部４１ａを通じて外部に露出する。そして、溶接用開口部４１ａの内周縁部と筒状部材２０の外周面とが溶接されている。   A rectangular welding opening 41 a is opened at the lower portion of the leg 41. As shown in FIG. 1B, when the leg portion 41 is overlapped with the outer peripheral surface of the cylindrical member 20, the outer peripheral surface of the cylindrical member 20 is exposed to the outside through the welding opening 41a. And the inner peripheral part of the opening part 41a for welding and the outer peripheral surface of the cylindrical member 20 are welded.

脚部４１の下端部は、図３に示すように、前後の外側に向けて折り曲げられており、取付穴４１ｂが形成されている。
図４に示すように、両脚部４１，４１の取付穴４１ｂ，４１ｂにボルト（図示せず）を挿入し、このボルトを車体３（図５参照）に取り付けることで、第二取付部材４０を車体３に取り付けることができる。
このように、前後二つの脚部４１，４１によってブラケット１０を車体３に取り付けることで、車体３に対するブラケット１０の安定性を高めることができる。 As shown in FIG. 3, the lower end portion of the leg portion 41 is bent toward the front and rear outer sides, and an attachment hole 41 b is formed.
As shown in FIG. 4, a bolt (not shown) is inserted into the mounting holes 41b and 41b of both the leg portions 41 and 41, and the second mounting member 40 is attached by attaching the bolt to the vehicle body 3 (see FIG. 5). It can be attached to the vehicle body 3.
Thus, by attaching the bracket 10 to the vehicle body 3 by the two front and rear leg portions 41, 41, the stability of the bracket 10 with respect to the vehicle body 3 can be enhanced.

上桁部４２は、振動側ブラケット２ａの上方に配置されており、振動側ブラケット２ａに対して上下方向（防振装置１の伸縮方向）に対向する部位である。
上桁部４２の中央部には、図２に示すように、連結用開口部４２ａが開口している（図３（ａ）参照）。
上桁部４２の上方から連結用開口部４２ａを通じて、ボルト（図示せず）を振動側ブラケット２ａおよび防振装置１の取付金具１ｂに組み付けることで、振動側ブラケット２ａを防振装置１に連結することができる。 The upper girder part 42 is disposed above the vibration side bracket 2a, and is a part facing the vibration side bracket 2a in the vertical direction (the expansion and contraction direction of the vibration isolator 1).
As shown in FIG. 2, a connecting opening 42a is opened at the center of the upper girder 42 (see FIG. 3A).
The vibration side bracket 2a is connected to the vibration isolator 1 by assembling a bolt (not shown) to the vibration side bracket 2a and the mounting bracket 1b of the vibration isolator 1 from above the upper girder 42 through the connection opening 42a. can do.

本実施形態のブラケット１０によって車体３に取り付けられた防振装置１では、振動側ブラケット２ａを介して入力されたエンジン２の振動をインシュレータ１ａの弾性変形によって吸収する。
振動によってインシュレータ１ａが弾性変形すると、オリフィス通路（図示せず）を作動液が流通し、オリフィス通路内に液柱共振が生じることで振動が減衰する。 In the vibration isolator 1 attached to the vehicle body 3 by the bracket 10 of the present embodiment, the vibration of the engine 2 input via the vibration side bracket 2a is absorbed by elastic deformation of the insulator 1a.
When the insulator 1a is elastically deformed by vibration, the working fluid flows through an orifice passage (not shown), and liquid column resonance occurs in the orifice passage, so that the vibration is attenuated.

振動側ブラケット２ａが下方に移動して、インシュレータ１ａが下方に向けて変位したときに、振動側ブラケット２ａの弾性当接部２ｂが第一取付部材３０のストッパ部３３に当接することで、振動側ブラケット２ａの下方への移動量が規制されている。このように、ストッパ部３３によって防振装置１の変位量が設定されている。
また、振動側ブラケット２ａが上方に移動して、インシュレータ１ａが上方に向けて変位したときに、振動側ブラケット２ａが第二取付部材４０の上桁部４２に当接することで、振動側ブラケット２ａの上方への移動量が規制されている。このように、第二取付部材４０の上桁部４２によって、防振装置１の変位量が設定されている。 When the vibration side bracket 2a moves downward and the insulator 1a is displaced downward, the elastic contact portion 2b of the vibration side bracket 2a makes contact with the stopper portion 33 of the first mounting member 30 to vibrate. The downward movement amount of the side bracket 2a is restricted. Thus, the amount of displacement of the vibration isolator 1 is set by the stopper portion 33.
Further, when the vibration side bracket 2a moves upward and the insulator 1a is displaced upward, the vibration side bracket 2a comes into contact with the upper girder portion 42 of the second mounting member 40, whereby the vibration side bracket 2a. The amount of movement upward is restricted. Thus, the displacement amount of the vibration isolator 1 is set by the upper girder part 42 of the second mounting member 40.

以上のようなブラケット１０では、図２に示すように、ステー３２およびストッパ部３３が第一取付部材３０に一体に形成されているため、ステー３２およびストッパ部３３の強度を高めることができる。
そして、ステー３２およびストッパ部３３を一体に形成することで、部品点数が少なくなるため、ブラケット１０の各部品を接合するときの溶接長さを小さくすることができる。ひいては、ブラケット１０の組立工数および部品点数を少なくし、ブラケット１０を軽量化するとともに、ブラケット１０の製造コストを低減することができる。 In the bracket 10 as described above, as shown in FIG. 2, the stay 32 and the stopper portion 33 are formed integrally with the first mounting member 30, so that the strength of the stay 32 and the stopper portion 33 can be increased.
And since the number of parts decreases by forming the stay 32 and the stopper part 33 integrally, the welding length when joining each component of the bracket 10 can be made small. As a result, the assembly man-hour and the number of parts of the bracket 10 can be reduced, the bracket 10 can be reduced in weight, and the manufacturing cost of the bracket 10 can be reduced.

また、ブラケット１０は、第一取付部材３０のステー３２側の部位（右側の部位）およびストッパ部３３側の部位（左側の部位）の二箇所で筒状部材２０に溶接されている。すなわち、第一取付部材３０は、第一取付部材３０への入力点を通過する直線上の二箇所で筒状部材２０に支持されている。
このように、ストッパ部３３の下面に筒状部材２０の上側開口端部２０ａが溶接され、ストッパ部３３が筒状部材２０の周壁部に安定して支持されるため、ストッパ部３３の強度を高めることができる。 In addition, the bracket 10 is welded to the tubular member 20 at two locations, a portion on the stay 32 side (right portion) and a portion on the stopper portion 33 side (left portion) of the first mounting member 30. That is, the first attachment member 30 is supported by the cylindrical member 20 at two locations on a straight line that passes through the input point to the first attachment member 30.
As described above, the upper opening end 20a of the tubular member 20 is welded to the lower surface of the stopper portion 33, and the stopper portion 33 is stably supported by the peripheral wall portion of the tubular member 20, so that the strength of the stopper portion 33 is increased. Can be increased.

また、図３（ｃ）に示すように、筒状部材２０の上側開口端部２０ａには前後の凹部２２，２２が形成されている。これにより、筒状部材２０を軽量化するとともに、筒状部材２０と平板部３１との溶接長さを小さくすることができる。
なお、図５に示すように、筒状部材２０において第一取付部材３０との接合部（筒状部材２０の右端部および左端部）には、壁部材２１の縁部２１ａ，２１ａ同士の接合部が配置されていない。したがって、筒状部材２０に凹部２２を形成しても、第一取付部材３０と筒状部材２０との接合部の強度を十分に確保することができる。 Further, as shown in FIG. 3C, front and rear recesses 22 are formed on the upper opening end 20 a of the tubular member 20. Thereby, while reducing the weight of the cylindrical member 20, the welding length of the cylindrical member 20 and the flat plate part 31 can be made small.
In addition, as shown in FIG. 5, in the tubular member 20, the edge portions 21 a and 21 a of the wall member 21 are joined to the joint portion (the right end portion and the left end portion of the tubular member 20) with the first mounting member 30. The part is not arranged. Therefore, even if the concave portion 22 is formed in the cylindrical member 20, the strength of the joint portion between the first mounting member 30 and the cylindrical member 20 can be sufficiently ensured.
