中空状のピラーに開口部が形成された構造の場合、開口部が設けられた部位の機械的強度が低下する。このようなピラーに衝突荷重が作用すると、開口部が設けられた部位に応力が集中し塑性変形し易くなるおそれがある。
In the case of the structure in which the opening is formed in the hollow pillar , the mechanical strength of the portion where the opening is provided is lowered. When a collision load acts on such a pillar , there is a possibility that stress concentrates on a portion where the opening is provided and plastic deformation is likely to occur.

そこで、本発明は、開口部が設けられたピラーの強度の低下を抑制できる車両の側部車体構造を提供することを目的とする。
Then, an object of this invention is to provide the side part vehicle body structure of the vehicle which can suppress the fall of the intensity | strength of the pillar provided with the opening part.

本発明の車両の側部車体構造は、開口部が形成されて車幅方向内側に位置するピラーインナと前記ピラーインナに対向する状態で前記ピラーインナに接合されて車幅方向外側に位置するピラーアウタとを有し、前記開口部を車幅方向内側へ向けるようにして車両の側部に配置されるとともに、車両前後方向に延びるロッカーに結合されて車両上下方向に延びる中空状のピラー、厚さ方向を車両上下方向に向けて前記ピラーインナと前記ピラーアウタとを結ぶように延びる横壁部を含みかつ前記開口部に挿入可能な筒状壁部と、前記筒状壁部から前記開口部の縁に沿うようにして前記開口部の外側に延びるフランジ部と、前記筒状壁部の車幅方向外側の端部を閉塞する底壁部とを有し、前記ピラーの前記開口部に挿入された状態で前記フランジ部が前記ピラーインナに結合されるとともに、前記底壁部が前記ピラーアウタに結合されることにより、前記ピラーインナと前記ピラーアウタとを結合する補強部材と、を備えることにより、上述した課題を解決する(請求項1)。
Side vehicle-body structure of a vehicle of the present invention, chromatic and the pillar outer panel which is opening is formed is joined to the pillar inner state opposite to the pillar inner and the pillar inner located inside in the vehicle width direction is located outward in the vehicle width direction and, wherein the opening and to direct the vehicle width direction inner side is arranged on the side of the vehicle Rutotomoni, a hollow pillar extending in the vehicle vertical direction is coupled to a rocker which extends in the longitudinal direction of the vehicle, the thickness direction A cylindrical wall portion including a lateral wall portion extending so as to connect the pillar inner and the pillar outer in a vertical direction of the vehicle, and being insertable into the opening portion, and extending along the edge of the opening portion from the cylindrical wall portion.

With part is coupled to the pillar inner, the bottom wall portion by being coupled to the pillar outer panel, by providing a reinforcing member for coupling the said pillar inner pillar outer, to solve the problems described above (according Item 1).

この発明によれば、横壁部を含む筒状壁部が開口部に挿入された状態でピラーインナピラーアウタとが補強部材にて結合される。このため、ピラーに車両前後方向から衝撃荷重が作用した場合であっても、その衝撃荷重の入力に対して横壁部が充分な抗力を発生させることができる。従って、開口部の形成によるピラーの強度低下を補強部材によって抑制することができる。しかも、筒状壁部がピラーを貫くように位置するのでピラーの曲げ剛性が高くなり、しかもフランジ部によって開口部の縁が補強されるので、開口部の変形が抑制されてピラーの機械的強度が向上する
According to this invention, the pillar inner and the pillar outer are coupled by the reinforcing member in a state where the cylindrical wall portion including the lateral wall portion is inserted into the opening. For this reason, even when an impact load acts on the pillar from the front-rear direction of the vehicle, the lateral wall portion can generate a sufficient resistance against the input of the impact load. Therefore, the strength reduction of the pillar due to the formation of the opening can be suppressed by the reinforcing member. Moreover, since the cylindrical wall portion is positioned so as to penetrate the pillar, the bending rigidity of the pillar is increased, and the edge of the opening is reinforced by the flange portion, so that the deformation of the opening is suppressed and the mechanical strength of the pillar is suppressed. Will improve .

本発明の車両の側部車体構造においては、補強部材が前記筒状壁部の空間を車両上下方向に仕切るように延びる補強壁部を有してもよい(請求項)。この場合、補強壁部が車両前後方向からの衝突荷重に対して充分な抗力を発生させることができるので、ピラーの強度低下の抑制効果が更に向上する。なお、補強壁部の数に制限はなく複数個設けてもよい。
In side vehicle-body structure of a vehicle of the present invention, it may have a reinforcing wall reinforcing member extends to partition the space of the cylindrical wall portion in the vehicle vertical direction (Claim 2). In this case, since the reinforcing wall portion can generate a sufficient resistance against the collision load from the vehicle front-rear direction, the effect of suppressing the decrease in pillar strength is further improved. The number of reinforcing wall portions is not limited and a plurality of reinforcing wall portions may be provided.

本発明のピラーは、車両のセンターピラーでもよいし、フロントピラーでもよい(請求項)。フロントピラーは、車両の前方衝突により前輪が後退し、前輪を介して衝撃荷重が入力される特有の問題がある。このため、開口部の形成によるフロントピラーの強度低下を可能な限り抑制することが望ましい。従って、フロントピラーに本発明の構造を適用することが有効である。
The pillar of the present invention may be a center pillar of a vehicle or a front pillar (claim 3 ). The front pillar has a peculiar problem that a front wheel moves backward due to a frontal collision of the vehicle and an impact load is input through the front wheel. For this reason, it is desirable to suppress the strength reduction of the front pillar due to the formation of the opening as much as possible. Therefore, it is effective to apply the structure of the present invention to the front pillar.

本発明の車両の側部車体構造において、前記補強部材は、所定のコネクタの保持及びその解除が可能なコネクタ保持機構を有していてもよい(請求項)。この態様によれば補強部材を周知のコネクタボックスとして機能させることができる。従って、開口部を補強部材にて補強した上でコネクタボックスを取付ける形態と比べ、部品点数を増加させることなく開口部を効果的に利用できる。
The side vehicle-body structure of a vehicle of the present invention, the reinforcing member may have a holding and releasing capable connector holding mechanism of a given connector (claim 4). According to this aspect, the reinforcing member can function as a known connector box. Therefore, the opening can be effectively used without increasing the number of parts, as compared with a mode in which the opening is reinforced by the reinforcing member and the connector box is attached.

以上説明したように、本発明によれば、厚さ方向を車両上下方向に向けてピラーインナピラーアウタとを結ぶように延びる横壁部を含む筒状壁部がピラーの開口部に挿入された状態で、ピラーインナとピラーアウタとが補強部材にて結合される。従って、ピラーに車両前後方向から衝撃荷重が作用した場合であっても、その衝撃荷重の入力に対して横壁部が充分な抗力を発生させることができ、開口部の形成によるピラーの強度低下を抑制できる。しかも、筒状壁部がピラーを貫くように位置するのでピラーの曲げ剛性が高くなり、しかもフランジ部によって開口部の縁が補強されるので、開口部の変形が抑制されてピラーの機械的強度が向上する
As described above, according to the present invention, the cylindrical wall portion including the lateral wall portion extending so as to connect the pillar inner and the pillar outer with the thickness direction directed in the vehicle vertical direction is inserted into the opening of the pillar. The pillar inner and the pillar outer are coupled by the reinforcing member. Therefore, even when an impact load acts on the pillar from the front and rear direction of the vehicle, the lateral wall portion can generate a sufficient resistance against the input of the impact load, and the strength of the pillar is reduced due to the formation of the opening. Can be suppressed. Moreover, since the cylindrical wall portion is positioned so as to penetrate the pillar, the bending rigidity of the pillar is increased, and the edge of the opening is reinforced by the flange portion, so that the deformation of the opening is suppressed and the mechanical strength of the pillar is suppressed. Will improve .

図1〜図3は本発明の実施形態を示し、図1は側部車体構造の要部を車室側から示した分解斜視図、図2は図1の補強部材を取付けた状態でのI-I線断面図、図3は図2のA部の部分拡大図である。これらの図においてFRは車両前方を、UPは車両上方を、INは車幅方向内側をそれぞれ示す(その他の図についても同じ)。
(First embodiment)
1 to 3 show an embodiment of the present invention, FIG. 1 is an exploded perspective view showing a main part of a side body structure from the passenger compartment side, and FIG. FIG. 3 is a partially enlarged view of a portion A in FIG. In these drawings, FR indicates the front of the vehicle, UP indicates the upper side of the vehicle, and IN indicates the inner side in the vehicle width direction (the same applies to the other drawings).

図1に示すように、車両の側部には車両前後方向に延びるロッカー3の前端部から車両上下方向に延びるようにしてフロントピラー(ピラー)2が設けられている。フロントピラー2は車幅方向内側のフロントピラーインナ(ピラーインナ)4と外側のフロントピラーアウタ(ピラーアウタ)5とが対向するようにして接合されて中空状に構成されている。フロントピラーインナ4の下部には開口部6が形成され、この開口部6に補強部材11が挿入されてフロントピラーインナ4とフロントピラーアウタ5にそれぞれ結合される。フロントピラーアウタ5はその内面に取付けられたフロントピラーアウタリインホースメント5aを有している(図2参照)。
As shown in FIG. 1, a front pillar ( pillar ) 2 is provided on a side portion of the vehicle so as to extend in the vehicle vertical direction from a front end portion of a rocker 3 extending in the vehicle front-rear direction. The front pillar 2 is composed and the vehicle width direction inner side of the front pillar inner (pillar inner) 4 and the outer front pillar outer (pillar outer) 5 is joined so as to face the hollow. An opening 6 is formed in the lower portion of the front pillar inner 4, and a reinforcing member 11 is inserted into the opening 6 and coupled to the front pillar inner 4 and the front pillar outer 5. The front pillar outer 5 has a front pillar outer reinforcement 5a attached to the inner surface thereof (see FIG. 2).

図1及び図2に示すように、補強部材11は断面矩形状で開口部6に挿入可能な筒状壁部12と、筒状壁部12の車幅方向の一端部から開口部6の縁6aに沿うようにして開口部6の外側に延びるフランジ部13と、筒状壁部12の車幅方向の他端部を閉塞する底壁部14と、を有した箱状体である。補強部材11は鋼板等の金属板がプレス加工されて構成されている。補強部材11の材質及び加工方法は種々のものを採用できる。例えば金属材料の鋳造で形成してもよいし、樹脂材料の射出成形で形成してもよい。   As shown in FIGS. 1 and 2, the reinforcing member 11 has a rectangular cross section and can be inserted into the opening 6, and the edge of the opening 6 from one end of the cylindrical wall 12 in the vehicle width direction. This is a box-like body having a flange portion 13 that extends to the outside of the opening 6 along 6a and a bottom wall portion 14 that closes the other end portion of the cylindrical wall portion 12 in the vehicle width direction. The reinforcing member 11 is configured by pressing a metal plate such as a steel plate. Various materials and processing methods can be used for the reinforcing member 11. For example, it may be formed by casting a metal material, or may be formed by injection molding of a resin material.

補強部材11の筒状壁部12は、厚さ方向が車両上下方向に向けられてフロントピラーインナ4とフロントピラーアウタ5とを結ぶように延びる一対の横壁部16,16と、横壁部16,16を連結する側壁部17,17とを含んでいる。フランジ部13の外縁は開口部6よりも大きく構成されていて、補強部材11を開口部6に挿入したときにフランジ部13とフロントピラーインナ4とが突き当たる。なお、開口部6の縁6aにフランジ部13を受け入れることができる窪みを形成し、フランジ部13がフロントピラーインナ4に突き当たったときにこれらの表面の高さが揃うように構成してもよい。   The cylindrical wall portion 12 of the reinforcing member 11 has a pair of lateral wall portions 16 and 16 extending so as to connect the front pillar inner 4 and the front pillar outer 5 with the thickness direction directed in the vehicle vertical direction, 16 and side wall portions 17 and 17 for connecting 16 to each other. The outer edge of the flange portion 13 is configured to be larger than the opening portion 6, and the flange portion 13 and the front pillar inner 4 abut against each other when the reinforcing member 11 is inserted into the opening portion 6. A recess capable of receiving the flange portion 13 is formed in the edge 6a of the opening 6 so that when the flange portion 13 abuts against the front pillar inner 4, the heights of these surfaces are aligned. .

フランジ部13の四隅及び左右にはそれぞれ一つずつ合計6個のボルト孔18…18が形成され、底壁部14の中央には左右並んだ状態で2個のボルト孔19,19が形成されている。一方、フロントピラーインナ4にはフランジ部13のボルト孔18に対応する位置に6個のボルト孔8…8が形成され、フロントピラーアウタリインホースメント5aには底壁部14のボルト孔19に対応する位置に2個のボルト孔9,9が形成されている(図2及び図3参照)。補強部材11は開口部6に挿入された状態でフランジ部13とフロントピラーインナ4とがボルト孔19,9に挿入されたボルト70とナット71で結合され、底壁部14とフロントピラーアウタリインホースメント5aとがボルト孔18,8に挿入されたボルト70とナット71にて結合される。これによって、フロントピラーインナ4とフロントピラーアウタ5とが補強部材11にて結合される。補強部材11とフロントピラー2との結合手段には特に制限がなく、リベット等の締結手段や、溶接、ろう付け、接着等の接合手段でも構わない。結合箇所も任意に定めることができ、接合手段を用いる場合にはスポット溶接のように部分的に接合してもよいし、シーム溶接のように全周を接合してもよい。   A total of six bolt holes 18... 18 are formed at each of the four corners and the left and right sides of the flange portion 13, and two bolt holes 19, 19 are formed in the center of the bottom wall portion 14 in a state of being arranged side by side. ing. On the other hand, the front pillar inner 4 is formed with six bolt holes 8... 8 at positions corresponding to the bolt holes 18 of the flange portion 13, and the front pillar outer reinforcement 5 a is formed with the bolt holes 19 of the bottom wall portion 14. Two bolt holes 9, 9 are formed at corresponding positions (see FIGS. 2 and 3). In the state in which the reinforcing member 11 is inserted into the opening 6, the flange portion 13 and the front pillar inner 4 are joined by the bolt 70 and the nut 71 inserted into the bolt holes 19 and 9, and the bottom wall portion 14 and the front pillar outer rein The hosement 5 a is coupled to the bolt 70 inserted in the bolt holes 18 and 8 and the nut 71. As a result, the front pillar inner 4 and the front pillar outer 5 are coupled by the reinforcing member 11. There are no particular restrictions on the means for joining the reinforcing member 11 and the front pillar 2, and fastening means such as rivets or joining means such as welding, brazing, and adhesion may be used. The joining location can also be determined arbitrarily. When a joining means is used, it may be partially joined like spot welding, or the entire circumference may be joined like seam welding.

以上の側部車体構造によれば、図4に示すように、車両の前方衝突により前輪10が後退し、衝突荷重Fが前輪10を介してフロントピラー2に入力された場合でも、補強部材11が設けられているので開口部6の形成によるフロントピラー2の強度低下が抑制される。より具体的には、筒状壁部12の横壁部16,16のそれぞれが前輪10からの入力に対して充分な抗力Nを発生させ、また側壁部17,17がフロントピラー2を貫くように位置するのでフロントピラー2の曲げ剛性が高くなる。しかも、フランジ部13によって開口部6の縁6aが補強されるので、開口部6の変形が抑制されてフロントピラー2の機械的強度が向上する。   According to the above-described side body structure, as shown in FIG. 4, even when the front wheel 10 moves backward due to a frontal collision of the vehicle and the collision load F is input to the front pillar 2 via the front wheel 10, the reinforcing member 11. Therefore, the strength reduction of the front pillar 2 due to the formation of the opening 6 is suppressed. More specifically, each of the lateral wall portions 16, 16 of the cylindrical wall portion 12 generates a sufficient drag N against the input from the front wheel 10, and the side wall portions 17, 17 penetrate the front pillar 2. Therefore, the bending rigidity of the front pillar 2 is increased. And since the edge 6a of the opening part 6 is reinforced by the flange part 13, a deformation | transformation of the opening part 6 is suppressed and the mechanical strength of the front pillar 2 improves.

更に筒状壁部12と底壁部14とで形成される空間S1をワイヤーハーネスの終端部に設けられたコネクタ、ヒューズ等の各種部品を収納する空間として利用できる。なお、図示を省略したが、車両ドア側のワイヤーハーネスと、車室側のワイヤーハーネスとを結線する際には、補強部材11の側壁部17に貫通孔を設け、この貫通孔にドア側のワイヤーハーネスを通し、補強部材11の空間S1内を利用してドア側のワイヤーハーネスと車両側のワイヤハーネスとをコネクタで結合することもできる。   Furthermore, the space S1 formed by the cylindrical wall portion 12 and the bottom wall portion 14 can be used as a space for storing various components such as connectors and fuses provided at the terminal end of the wire harness. Although illustration is omitted, when connecting the wire harness on the vehicle door side and the wire harness on the vehicle compartment side, a through hole is provided in the side wall portion 17 of the reinforcing member 11, and the door side is provided in the through hole. It is also possible to connect the wire harness on the door side and the wire harness on the vehicle side with a connector using the inside of the space S1 of the reinforcing member 11 through the wire harness.

参考例
次に本発明の参考例について説明する。この参考例は補強部材の構成のみが第1の実施形態と相違する。図5に示す補強部材21も第1の実施形態と同様に、フロントピラー2の開口部6に挿入された状態でフロントピラーインナ4とフロントピラーアウタ5とを結合する。補強部材21は車両上下方向に並ぶ一対の横壁部26,26と、各横壁部26の車幅方向の一端部から開口部6の縁6aの上辺に沿うようにして開口部6の外側に延びる取付け部23,23と、各横壁部26の車幅方向の他端部を互いに結び、車両上下方向に延びる上下壁部24と、を有している。各取付け部26には二つずつ合計4個のボルト孔28,28が形成され、上下壁部24にはその中央に並ぶ二つのボルト孔29,29が形成されている。図5の参考例においても、補強部材21が開口部6に挿入された状態で、取付け部26がフロントピラーインナ4に、上下壁部24がフロントピラーアウタ5に、それぞれ不図示のボルト及びナットを介して結合される。図5に示す補強部材21は鋼板等の金属板のプレス加工により形成されたものであるが、例えば金属材料の鋳造で形成してもよいし、樹脂材料の射出成形で形成してもよい。
( Reference example )
Next , reference examples of the present invention will be described. This reference example is different from the first embodiment only in the configuration of the reinforcing member. Similarly to the first embodiment, the reinforcing member 21 shown in FIG. 5 joins the front pillar inner 4 and the front pillar outer 5 while being inserted into the opening 6 of the front pillar 2. The reinforcing member 21 extends to the outside of the opening 6 along the upper side of the edge 6a of the opening 6 from a pair of horizontal walls 26, 26 arranged in the vehicle vertical direction and one end of each horizontal wall 26 in the vehicle width direction. It has attachment parts 23 and 23, and the upper-and-lower wall part 24 which mutually connects the other end part of the width direction of each horizontal wall part 26, and extends in the vehicle up-and-down direction. A total of four bolt holes 28, 28 are formed in each mounting portion 26, and two bolt holes 29, 29 arranged in the center are formed in the upper and lower wall portions 24. Also in the reference example of FIG. 5, with the reinforcing member 21 inserted into the opening 6, the mounting portion 26 is on the front pillar inner 4, and the upper and lower wall portions 24 are on the front pillar outer 5, respectively. Is coupled through. The reinforcing member 21 shown in FIG. 5 is formed by pressing a metal plate such as a steel plate, but may be formed, for example, by casting a metal material or by injection molding of a resin material.

この参考例の側部車体構造によれば、簡素な構成で第1の実施形態と同様の作用効果を奏することができる。即ち、横壁部26,26のそれぞれが前輪10を介して入力される衝突荷重に対して充分な抗力を発生させ、また横壁部26の車両前後方向の端部26a,26aがフロントピラー2を貫くように位置するのでフロントピラー2の曲げ剛性が高くなり、開口部6の形成によるフロントピラー2の強度低下が抑制される。
According to the side body structure of this reference example , the same effects as those of the first embodiment can be achieved with a simple configuration. That is, each of the lateral wall portions 26, 26 generates a sufficient resistance against a collision load input via the front wheel 10, and the vehicle longitudinal direction ends 26 a, 26 a of the lateral wall portion 26 penetrate the front pillar 2. Therefore, the bending rigidity of the front pillar 2 is increased, and the strength reduction of the front pillar 2 due to the formation of the opening 6 is suppressed.

Is coupled through.

この実施形態の側部車体構造によれば、各補強壁部35が前輪10を介して入力される衝突荷重に対して充分な抗力を発生させることができるので、開口部6の形成によるフロントピラー2の強度低下の抑制効果が第1の実施形態の場合よりも更に向上する。   According to the side body structure of this embodiment, each reinforcing wall 35 can generate a sufficient resistance against a collision load input via the front wheel 10, so that the front pillar is formed by forming the opening 6. 2 is further improved as compared with the case of the first embodiment.

次に第の実施形態について説明する。この実施形態は第1又は第2のいずれかの形態と組み合わされて実施されるもので、ワイヤーハーネスの終端部に設けられた所定のコネクタを補強部材で保持可能に構成したものである。なお、以下の説明では、便宜上、第1の実施形態に係る補強部材11に関する符号を使用して説明するが、他の補強部材への本実施形態の適用を排除するものではない。図7(a)に示すように、コネクタ保持機構40は図8(a)に示すコネクタ42の底面に設けられた係合部43と互いに嵌り合うように形成された爪状片44を有している。この図から明らかなように、爪状片44は、横壁部16を一辺44aが繋がった状態で所定の形状に打ち抜いて、その一辺44aで折り曲げるように立ち上げて構成したものである。なお、爪状片44はろう付け等の接合手段によって横壁部16に設けてもよい。図8(a)のコネクタ42の係合部43を爪状片44に差し込むことにより、補強部材11にコネクタ42を保持させることができる。これにより、部品点数を増大させることなく、補強部材11をいわゆるコネクタボックスとして機能させることができる。なお、コネクタ保持機構40は横壁部16の他、側壁部17に設けてもよいし、第の実施形態の補強壁部35に設けることもできる。
( Third embodiment)
Next, a third embodiment will be described. This embodiment is implemented in combination with either the first or second embodiment, and is configured such that a predetermined connector provided at the terminal portion of the wire harness can be held by a reinforcing member. In addition, in the following description, although the code | symbol regarding the reinforcement member 11 which concerns on 1st Embodiment is used for convenience, it demonstrates, but application of this embodiment to another reinforcement member is not excluded. As shown in FIG. 7A, the connector holding mechanism 40 has a claw-like piece 44 formed so as to be fitted to the engaging portion 43 provided on the bottom surface of the connector 42 shown in FIG. ing. As is apparent from this figure, the claw-shaped piece 44 is formed by punching the horizontal wall portion 16 into a predetermined shape with one side 44a connected, and standing up so as to be bent at the one side 44a. The claw-like piece 44 may be provided on the lateral wall portion 16 by a joining means such as brazing. The connector 42 can be held by the reinforcing member 11 by inserting the engaging portion 43 of the connector 42 of FIG. Accordingly, the reinforcing member 11 can function as a so-called connector box without increasing the number of parts. The connector holding mechanism 40 may be provided on the side wall portion 17 in addition to the lateral wall portion 16, or may be provided on the reinforcing wall portion 35 of the second embodiment.

この実施形態のコネクタ保持機構40は保持すべきコネクタの形状に応じて適宜に構成すればよい。例えば、図8(b)に示すように、コネクタ45が爪状片46を有している場合には、コネクタ保持機構40として、図7(b)に示すように、コネクタ46の爪状片46が嵌るような係合部47を横壁部16に設けてもよい。この場合、係合部47はろう付け等の接合手段で横壁部16に設けてもよいし、図7(a)の爪状片44のように、横壁部16を打ち抜いて構成してもよい。なお、図7(b)のコネクタ保持機構40も側壁部17に設けてもよいし、第の実施形態の補強壁部35に設けてもよい。
The connector holding mechanism 40 of this embodiment may be appropriately configured according to the shape of the connector to be held. For example, when the connector 45 has a claw-like piece 46 as shown in FIG. 8B, the connector holding mechanism 40 is used as the claw-like piece of the connector 46 as shown in FIG. An engaging portion 47 that fits 46 may be provided on the lateral wall portion 16. In this case, the engaging portion 47 may be provided on the lateral wall portion 16 by a joining means such as brazing, or may be configured by punching the lateral wall portion 16 like the claw-like piece 44 in FIG. . In addition, the connector holding mechanism 40 of FIG.7 (b) may also be provided in the side wall part 17, and may be provided in the reinforcement wall part 35 of 2nd Embodiment.

本発明は以上の実施形態に限定されず、本発明の要旨の範囲内で種々の形態で実施できる。図2では、補強部材1がフロントピラーアウタリインホースメント5aに結合しているが、これをフロントピラーアウタ5に直接結合してもよい。また、6においては、補強部材31がフロントピラーアウタ5と結合しているが、フロントピラーアウタリインホースメント5aがある場合、補強部材31をフロントピラーアウタリインホースメント5aに結合してもよいし、フロントピラーアウタ5に結合してもよい
The present invention is not limited to the above embodiment, and can be implemented in various forms within the scope of the gist of the present invention. In FIG. 2, the reinforcing member 11 is coupled to the front pillar outer reinforcement 5 a, but it may be coupled directly to the front pillar outer 5. Further, in FIG. 6, the reinforcing member 3 1 is attached to the front pillar outer 5, if there is a front pillar outer reinforcement 5a, coupling the reinforcing member 3 1 to the front pillar outer reinforcement 5a Alternatively, it may be coupled to the front pillar outer 5 .

また、本発明の他の参考例としては、図9に示すように、フロントピラー2を貫くようにフロントピラーインナ4とフロントピラーアウタ5の両者に開口部60を設け、この開口部60、60に補強部材51を挿入した状態でフロントピラーインナ4とフロントピラーアウタ5とを補強部材51にて結合することができる。この場合、フロントピラーインナ4側、及びフロントピラーアウタ5側の両方にフランジ部53,53を設けるとよい。フロントピラーアウタ5がフロントピラーアウタリインホースメントを有している場合には、補強部材51をフロントピラーアウタリインホースメント5aに結合してもよい。
As another reference example of the present invention, as shown in FIG. 9, an opening 60 is provided in both the front pillar inner 4 and the front pillar outer 5 so as to penetrate the front pillar 2. The front pillar inner 4 and the front pillar outer 5 can be coupled by the reinforcing member 51 in a state where the reinforcing member 51 is inserted in the reinforcing member 51. In this case, it is good to provide the flange parts 53 and 53 in both the front pillar inner 4 side and the front pillar outer 5 side. When the front pillar outer 5 has a front pillar outer reinforcement, the reinforcing member 51 may be coupled to the front pillar outer reinforcement 5a.

以上説明した補強部材の横壁部の表面は平坦であってもよいし、例えば、図10(a)に示すように、車両前後方向に延びるリブ65を設けてもよいし、図10(b)に示すように、車両前後方向に延びるビード66を設けてもよい。リブ65やビード66等の補強加工を補強部材の横壁部に施した場合には、重量を殆ど増加させずに横壁部の強度を向上させることができる。   The surface of the lateral wall portion of the reinforcing member described above may be flat, for example, as shown in FIG. 10A, a rib 65 extending in the vehicle front-rear direction may be provided, or FIG. As shown, a bead 66 extending in the vehicle front-rear direction may be provided. When reinforcing processing of the rib 65, the bead 66, or the like is performed on the lateral wall portion of the reinforcing member, the strength of the lateral wall portion can be improved without substantially increasing the weight.

以上の説明では、本発明の側部車体構造をフロントピラーに適用した形態を例示したが、本発明の適用対象はフロントピラーに限定されるものではなく、開口部が設けられて車両上下方向に延びる中空状のピラーであれば、例えばセンターピラー等に本発明を適用することもできる。
