That is, the first connecting portion 31 is disposed closer to the steering column 5 than the first flange portion 22b of the first rear bracket 22 in the vehicle width direction X.
　第２連結部３２は、第１連結部３１と同様に形成される。第２連結部３２は、前側ブラケット２１の第２フランジ部２１ｃが延在して形成される。第２連結部３２は、第２フランジ部２１ｃの基部（運転席側パイプ３ａへの接続部）に向けて、末広がり形状に形成される。 ２The second connecting portion 32 is formed similarly to the first connecting portion 31. The second connecting portion 32 is formed by extending the second flange portion 21c of the front bracket 21. The second connection portion 32 is formed in a divergent shape toward the base of the second flange portion 21c (connection portion to the driver seat side pipe 3a).
　第２連結部３２は、第２後側ブラケット２３の第２ウェブ部２３ａに乗り上げて、運転席側パイプ３ａと、第２後側ブラケット２３の第２ウェブ部２３ａと、に溶接などによって取り付けられる。すなわち、第２連結部３２は、第２フランジ部２１ｃと、運転席側パイプ３ａと、第２後側ブラケット２３の第２ウェブ部２３ａと、を接続する。 The second connecting portion 32 rides on the second web portion 23a of the second rear bracket 23 and is attached to the driver side pipe 3a and the second web portion 23a of the second rear bracket 23 by welding or the like. . That is, the second connecting portion 32 connects the second flange portion 21c, the driver seat side pipe 3a, and the second web portion 23a of the second rear bracket 23.
　すなわち、第２連結部３２は、前側ブラケット２１と第２後側ブラケット２３との間を、運転席側パイプ３ａの周方向に沿って運転席側パイプ３ａに溶接されている。言い換えると、第２連結部３２は、前側ブラケット２１における運転席側パイプ３ａの溶接箇所から、第２後側ブラケット２３における運転席側パイプ３ａの溶接箇所に至るまで、運転席側パイプ３ａに溶接して固定される。 That is, the second connecting portion 32 is welded to the driver side pipe 3a between the front bracket 21 and the second rear bracket 23 along the circumferential direction of the driver side pipe 3a. In other words, the second connecting portion 32 is welded to the driver side pipe 3a from the welding point of the driver side pipe 3a on the front bracket 21 to the welding point of the driver side pipe 3a on the second rear bracket 23. And fixed.

That is, the second connecting portion 32 is disposed closer to the steering column 5 than the first flange portion 23b of the second rear bracket 23 in the vehicle width direction X.
　［ステアリングメンバ構造の作用］
　図５は、実施例１のステアリングメンバ構造の比較例を説明する説明図である。以下、実施例１のステアリングメンバ構造の作用について説明する。なお、図５は、比較例の作用を分かりやすくするために、やや誇張した記載とする。 [Operation of steering member structure]
FIG. 5 is an explanatory diagram illustrating a comparative example of the steering member structure according to the first embodiment. Hereinafter, the operation of the steering member structure according to the first embodiment will be described. Note that FIG. 5 is slightly exaggerated for easy understanding of the operation of the comparative example.
　実施例１のステアリングメンバ構造は、車両幅方向Ｘに延びるメンバ本体３に取り付けられて、ステアリングコラム５を支持する支持部材（コラムブラケット２０）を有するステアリングメンバ構造であって、支持部材（コラムブラケット２０）は、車両前後方向Ｙでメンバ本体３の前側に位置し、一端がメンバ本体３に取り付けられ、他端がステアリングコラム５に固定される前側支持部材（前側ブラケット２１）と、車両前後方向Ｙでメンバ本体３の後側に位置し、一端がメンバ本体３に取り付けられ、他端がステアリングコラム５に固定される後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）と、前側支持部材（前側ブラケット２１）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）と、メンバ本体３と、を連結する連結部（第１連結部３１，第２連結部３２）と、を備える（図２）。 The steering member structure according to the first embodiment has a support member (column bracket 20) attached to a member main body 3 extending in the vehicle width direction X and supporting the steering column 5; 20) is a front support member (front bracket 21) which is located on the front side of the member main body 3 in the vehicle front and rear direction Y, one end of which is attached to the member main body 3 and the other end of which is fixed to the steering column 5; Rear support members (first rear bracket 22, second rear bracket 23) which are located on the rear side of the member main body 3 at Y, one end is attached to the member main body 3, and the other end is fixed to the steering column 5. A front support member (front bracket 21), a rear support member (first rear bracket 22, second rear bracket 23), And Nba body 3, a connecting portion for connecting the (first connecting portion 31, second connecting portion 32), and a (Figure 2).
　これにより、前側支持部材（前側ブラケット２１）と後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）との間のメンバ本体３の部分に加わる応力を、連結部（第１連結部３１，第２連結部３２）を通して分散することができる。そのため、前側支持部材（前側ブラケット２１）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）との間のメンバ本体３の部分への応力を低減することができる。その結果、メンバ本体３の肉厚化、ひいては重量増加を抑制することができる。 Thus, the stress applied to the portion of the member body 3 between the front support member (the front bracket 21) and the rear support member (the first rear bracket 22, the second rear bracket 23) is reduced by the connecting portion (the first bracket 21). It can be dispersed through the connecting portion 31 and the second connecting portion 32). Therefore, stress on the portion of the member body 3 between the front support member (the front bracket 21) and the rear support member (the first rear bracket 22, the second rear bracket 23) can be reduced. As a result, it is possible to suppress an increase in the thickness of the member main body 3 and an increase in the weight.
　この作用について、以下に詳細にする。ステアリングコラム５は、ステアリングホイール５１やエアバッグ５２などの重量のある部品が取り付けられるため、振動によってステアリングコラム５が撓む。ここで、図５に示すように、仮に、連結部を備えないステアリングメンバ５０１の場合について考える。このようなステアリングメンバ５０１が、誇張した表現ではあるが、図中上側に弓なりに撓む（以下、弓なりに撓むとは、ステアリングコラム５が微小に湾曲することを含む趣旨である。）と、前側ブラケット２１が、メンバ本体３を軸として、反時計回りに回転する力（反時計回りのモーメント）をメンバ本体３に入力し、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）が、メンバ本体３を軸として、時計回りに回転する力（時計周りのモーメント）をメンバ本体３に入力する。この場合、前側ブラケット２１と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）と、の間のメンバ本体３の部分に圧縮力が加わる。 This action will be described in detail below. Since heavy components such as the steering wheel 51 and the airbag 52 are attached to the steering column 5, the steering column 5 bends due to vibration. Here, as shown in FIG. 5, suppose a case where the steering member 501 does not include the connecting portion. Although such a steering member 501 is exaggerated, it bows upward in the drawing (hereinafter, bowing in the bowing means that the steering column 5 is slightly curved). The bracket 21 inputs a counterclockwise rotating force (counterclockwise moment) about the member main body 3 to the member main body 3, and the rear support members (the first rear bracket 22 and the second rear bracket 22). 23) inputs to the member body 3 a force that rotates clockwise about the member body 3 (clockwise moment). In this case, a compressive force is applied to the portion of the member main body 3 between the front bracket 21 and the rear support members (the first rear bracket 22 and the second rear bracket 23).
　一方、特に図示しないが、ステアリングコラム５が図中下側に弓なりに撓むことで、前側ブラケット２１が、メンバ本体３を軸として、時計回りに回転する力（時計回りのモーメント）をメンバ本体３に入力し、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）が、メンバ本体３を軸として、反時計回りに回転する力（反時計周りのモーメント）をメンバ本体３に入力する。この場合、前側ブラケット２１と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）と、の間のメンバ本体３の部分に引張力が加わる。 On the other hand, although not particularly shown, the steering column 5 bends downwardly in the figure so that the front bracket 21 applies a clockwise rotating force (clockwise moment) about the member body 3 to the member body. 3, the rear support members (the first rear bracket 22, the second rear bracket 23) apply a counterclockwise rotating force (counterclockwise moment) about the member main body 3 to the member main body. Enter 3 In this case, a tensile force is applied to the portion of the member body 3 between the front bracket 21 and the rear support members (the first rear bracket 22 and the second rear bracket 23).
　このような圧縮力や引張力に耐えるために、例えば、メンバ本体の肉厚を厚くしたり、メンバ本体の径を大きくしたりして、メンバ本体の強度を上げる必要が生じる。その結果、メンバ本体の重量が重くなってしまう、という問題がある。 耐 え In order to withstand such a compressive or tensile force, it is necessary to increase the strength of the member body, for example, by increasing the thickness of the member body or increasing the diameter of the member body. As a result, there is a problem that the weight of the member body becomes heavy.
　これに対して、実施例１のステアリングメンバ構造では、連結部（第１連結部３１，第２連結部３２）が、前側支持部材（前側ブラケット２１）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）と、メンバ本体３と、を連結するため、前側支持部材（前側ブラケット２１）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）との間のメンバ本体３の部分に加わる応力を、連結部（第１連結部３１，第２連結部３２）を通して分散することができる。 On the other hand, in the steering member structure according to the first embodiment, the connecting portions (the first connecting portion 31 and the second connecting portion 32) include the front support member (the front bracket 21) and the rear support member (the first rear side). In order to connect the bracket 22, the second rear bracket 23) and the member body 3, the front support member (the front bracket 21) and the rear support member (the first rear bracket 22, the second rear bracket 23). ) Can be dispersed through the connecting portions (the first connecting portion 31 and the second connecting portion 32).
　例えば、ステアリングコラム５が振動して上側に弓なりに撓み、前側ブラケット２１が、メンバ本体３を軸として、反時計回りに回転する力（反時計回りのモーメント）を生じ、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）が、メンバ本体３を軸として、時計回りに回転する力（時計周りのモーメント）を生じた場合でも、前側支持部材（前側ブラケット２１）と後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）との間の連結部（第１連結部３１，第２連結部３２）が両者のモーメントに対する抗力を生じるため、メンバ本体３にモーメントが入力されるのを抑制できる。 For example, the steering column 5 vibrates and bows upward in an arcuate manner, and the front bracket 21 generates a counterclockwise rotating force (counterclockwise moment) about the member main body 3, and the rear support member (the Even when the first rear bracket 22 and the second rear bracket 23) generate a clockwise rotating force (clockwise moment) around the member body 3, the front support member (the front bracket 21) and the rear Since the connecting portions (the first connecting portion 31 and the second connecting portion 32) between the side supporting members (the first rear bracket 22 and the second rear bracket 23) generate a drag force against both moments, the member body 3 is formed. Input of a moment can be suppressed.
　逆に、ステアリングコラム５が振動して下側に弓なりに撓んだ場合においても、前側支持部材（前側ブラケット２１）と後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）によるモーメントに対し、連結部（第１連結部３１，第２連結部３２）が抗力を発生させる。このように、上述したメンバ本体３に、圧縮力や引張力が入力されるのを抑制することができるため、メンバ本体３の肉厚化や大径化を抑制することができる。 Conversely, even when the steering column 5 vibrates and bows downward in a bowed manner, the front support member (the front bracket 21) and the rear support member (the first rear bracket 22, the second rear bracket 23). The connecting portions (the first connecting portion 31 and the second connecting portion 32) generate a drag with respect to the moment due to. As described above, the input of a compressive force or a tensile force to the above-described member main body 3 can be suppressed, so that the thickness and the diameter of the member main body 3 can be suppressed from increasing.
　なお、前側支持部材と後側支持部材の２部材で分割した支持部材を構成しているため、前側支持部材と、後側支持部材との間に空間を形成することができる。その結果、軽量化したステアリングメンバ構造とすることができる。 た め Because the support member is divided into two members, the front support member and the rear support member, a space can be formed between the front support member and the rear support member. As a result, a lightweight steering member structure can be obtained.
　実施例１のステアリングメンバ構造では、前側支持部材（前側ブラケット２１）は、ウェブ部２１ａと、ウェブ部２１ａの車両幅方向Ｘの両端から下方に延在する、ステアリングコラム５が取り付けられるフランジ部（第１フランジ部２１ｂ，第２フランジ部２１ｃ）と、を備え、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）は、ステアリングコラム５が取り付けられるウェブ部（第１ウェブ部２２ａ，第２ウェブ部２３ａ）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）のウェブ部（第１ウェブ部２２ａ，第２ウェブ部２３ａ）の車両幅方向Ｘの両端から上方に延在するフランジ部（第１フランジ部２２ｂ，第２フランジ部２２ｃ，第１フランジ部２３ｂ，第２フランジ部２３ｃ）と、を備え、連結部（第１連結部３１，第２連結部３２）は、前側支持部材（前側ブラケット２１）のフランジ部（第１フランジ部２１ｂ，第２フランジ部２１ｃ）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）のウェブ部（第１ウェブ部２２ａ，第２ウェブ部２３ａ）と、メンバ本体３と、を連結する（図２）。 In the steering member structure of the first embodiment, the front support member (the front bracket 21) extends downward from both ends of the web portion 21a in the vehicle width direction X of the web portion 21a. A first flange portion 21b, a second flange portion 21c), and a rear support member (first rear bracket 22, second rear bracket 23) is provided with a web portion (first web) to which the steering column 5 is attached. 22a, the second web portion 23a) and the web portion (the first web portion 22a, the second web portion 23a) of the rear support member (the first rear bracket 22, the second rear bracket 23) in the vehicle width direction. A flange portion (first flange portion 22b, second flange portion 22c, first flange portion 23b, second flange portion 23c) extending upward from both ends of X; The connecting portions (the first connecting portion 31 and the second connecting portion 32) include a flange portion (a first flange portion 21b and a second flange portion 21c) of a front support member (a front bracket 21) and a rear support member ( The web portions (the first web portion 22a and the second web portion 23a) of the first rear bracket 22 and the second rear bracket 23 are connected to the member body 3 (FIG. 2).
　これにより、前側支持部材（前側ブラケット２１）のフランジ部（第１フランジ部２１ｂ，第２フランジ部２１ｃ）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）のウェブ部（第１ウェブ部２２ａ，第２ウェブ部２３ａ）との間のメンバ本体３の部分に加わる応力を、連結部（第１連結部３１，第２連結部３２）を通して分散することができる。そのため、前側支持部材（前側ブラケット２１）と、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）との間のメンバ本体３の部分に加わる応力を低減することができる。その結果、メンバ本体３の肉厚化、ひいては重量増加を抑制することができる。 Accordingly, the flange portions (first flange portion 21b, second flange portion 21c) of the front support member (front bracket 21) and the webs of the rear support members (first rear bracket 22, second rear bracket 23) are provided. The stress applied to the portion of the member main body 3 between the portions (the first web portion 22a and the second web portion 23a) can be dispersed through the connection portions (the first connection portion 31 and the second connection portion 32). Therefore, stress applied to the portion of the member body 3 between the front support member (the front bracket 21) and the rear support member (the first rear bracket 22, the second rear bracket 23) can be reduced. As a result, it is possible to suppress an increase in the thickness of the member main body 3 and an increase in the weight.
　実施例１のステアリングメンバ構造では、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）は、車両幅方向Ｘで、ステアリングコラム５の一方の側に配置される第１後側支持部材（第１後側ブラケット２２）と、車両幅方向Ｘで、ステアリングコラム５の他方の側に配置される第２後側支持部材（第２後側ブラケット２３）と、を備える（図２）。 In the steering member structure of the first embodiment, the rear support members (the first rear bracket 22 and the second rear bracket 23) are disposed on one side of the steering column 5 in the vehicle width direction X. A side support member (first rear bracket 22) and a second rear support member (second rear bracket 23) arranged on the other side of the steering column 5 in the vehicle width direction X (FIG. 2). 2).
　これにより、ステアリングコラム５を支持する箇所を増やすことができる。そのため、ステアリングコラム５の支持剛性を高めることができる。 Thereby, the number of locations for supporting the steering column 5 can be increased. Therefore, the support rigidity of the steering column 5 can be increased.
　実施例１のステアリングメンバ構造は、連結部（第１連結部３１，第２連結部３２）の車両幅方向Ｘの位置は、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）のステアリングコラム５に近い方のフランジ部（第２フランジ部２２ｃ，第２フランジ部２３ｃ）の位置と略同じである（図２）。 In the steering member structure according to the first embodiment, the positions of the connecting portions (the first connecting portion 31 and the second connecting portion 32) in the vehicle width direction X are adjusted by the rear support members (the first rear bracket 22 and the second rear bracket). The position of the flange portion (the second flange portion 22c, the second flange portion 23c) closer to the steering column 5 in (23) is substantially the same (FIG. 2).
　これにより、前側支持部材（前側ブラケット２１）の、車両幅方向Ｘの幅を狭めることができる。そのため、前側支持部材（前側ブラケット２１）を軽量化することができる。 Thereby, the width of the front support member (the front bracket 21) in the vehicle width direction X can be reduced. Therefore, the weight of the front support member (the front bracket 21) can be reduced.
　図６は、実施例２のステアリングメンバの構成を示す斜視図である。以下、図６に基づいて、実施例２のステアリングメンバの構成について説明する。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。 FIG. 6 is a perspective view illustrating the configuration of the steering member according to the second embodiment. Hereinafter, the configuration of the steering member according to the second embodiment will be described with reference to FIG. The same or equivalent parts as those described in the first embodiment will be described using the same terms or the same reference numerals.
　実施例２のステアリングメンバ１０１は、前側ブラケットの構成が異なる点で、実施例１のステアリングメンバと相違する。 The steering member 101 of the second embodiment differs from the steering member of the first embodiment in that the configuration of the front bracket is different.
　前側ブラケット１２１のウェブ部１２１ａは、実施例１のウェブ部２１ａと比べて、車両幅方向Ｘに、広く形成される。 ウ ェ ブ The web portion 121a of the front bracket 121 is formed wider in the vehicle width direction X than the web portion 21a of the first embodiment.
　第１連結部３１は、車両幅方向Ｘで、第１後側ブラケット２２の第２フランジ部２２ｃより、ステアリングコラム５から遠くに配置される第１後側ブラケット２２の第１フランジ部２２ｂと、略同じ位置に配置される。 The first connecting portion 31 includes a first flange portion 22b of the first rear bracket 22 disposed farther from the steering column 5 than a second flange portion 22c of the first rear bracket 22 in the vehicle width direction X; They are arranged at substantially the same position.

　以下、実施例２のステアリングメンバ構造の作用について説明する。実施例２のステアリングメンバ構造は、連結部（第１連結部３１，第２連結部３２）の車両幅方向Ｘの位置は、後側支持部材（第１後側ブラケット２２，第２後側ブラケット２３）のステアリングコラム５から遠い方のフランジ部（第１フランジ部２２ｂ，第１フランジ部２３ｂ）の位置と略同じである（図６）。 Hereinafter, the operation of the steering member structure according to the second embodiment will be described. In the steering member structure according to the second embodiment, the positions of the connecting portions (the first connecting portion 31 and the second connecting portion 32) in the vehicle width direction X are set to the rear support members (the first rear bracket 22, the second rear bracket). 23) is substantially the same as the position of the flange portion (first flange portion 22b, first flange portion 23b) remote from the steering column 5 (FIG. 6).
　これにより、前側支持部材（前側ブラケット１２１）のフランジ部（第１フランジ部２１ｂ，第２フランジ部２１ｃ）と、前側支持部材（前側ブラケット１２１）のウェブ部１２１ａとで形成された空間を確保することができる。そのため、この空間に、ステアリングコラム５に付属する部品を収容することができる。なお、実施例２のこの他の構成及び作用効果については、実施例１と略同様であるため、説明を省略する。 This secures a space formed by the flange portions (first flange portion 21b and second flange portion 21c) of the front support member (front bracket 121) and the web portion 121a of the front support member (front bracket 121). be able to. Therefore, components attached to the steering column 5 can be accommodated in this space. The other configuration and operation and effect of the second embodiment are substantially the same as those of the first embodiment, and thus description thereof will be omitted.
