Yes.

つまり、図３に示すように、前記第１接合部列Ｌ１と、複数の第２接合部２２から成る第２接合部列Ｌ２とが車幅方向において並列に並んでいる。これにより、前記第１接合部列Ｌ１と第２接合部列Ｌ２から成る接合部全体の平面積を大きく、また、前記接合部の板厚部を幅広くとることができ、サイドボディ構造１の接合部の強度・剛性を向上することができる。その結果、図４に示すように、側面衝突時にサイドボディ構造１に力Ｆが加わった場合のサイドボディの変形を低減でき、しかも、車両前後方向の衝突時のサイドボディの変形を低減できて乗員の被害を低減できる。
さらに、サイドボディの変形を低減することで、側突時にルーフセンタメンバ３９に掛かる変形を緩和できるようになったため、ルーフセンタメンバ３９の構成を簡略化（板厚の低減）することができ、軽量化・コストダウンすることができる。 That is, as shown in FIG. 3, the first joint row L <b> 1 and the second joint row L <b> 2 including the plurality of second joint portions 22 are arranged in parallel in the vehicle width direction. Thereby, the plane area of the whole junction part which consists of said 1st junction part row | line | column L1 and 2nd junction part row | line | column L2 can be enlarged, and the board | plate thickness part of the said junction part can be taken widely, and joining of the side body structure 1 is possible. The strength and rigidity of the part can be improved. As a result, as shown in FIG. 4, the deformation of the side body when the force F is applied to the side body structure 1 at the time of the side collision can be reduced, and the deformation of the side body at the time of the collision in the vehicle longitudinal direction can be reduced. It can reduce passenger damage.
Further, by reducing the deformation of the side body, the deformation applied to the roof center member 39 at the time of a side collision can be alleviated. Therefore, the configuration of the roof center member 39 can be simplified (thickness reduction), It can be reduced in weight and cost.

図３に示すように、前記第１接合部列Ｌ１は第２接合部列Ｌ２よりも車幅方向外側Ｗ２に位置し、第１接合部列Ｌ１と第２接合部列Ｌ２は、車幅方向においてルーフパネル５側のサイドボディアウターパネル縦壁８Ｔ１（図５参照）を挟んで位置している。これにより、図６に示すように、ルーフサイドインナーレール６のフランジ６Ｆ１以外の部分を車幅方向外側Ｗ２に配置することができる（２点鎖線は比較例の構造のルーフサイドインナーレール６の位置を示している）。従って、必要なサイドボディの幅を狭くせず、サイドボディの剛性を低下させることなく、車室内のヘッドクリアランスＡを拡大することができる。その結果、側突時の搭乗者の頭部５０への障害値を低減することができる。   As shown in FIG. 3, the first joint row L1 is located on the outer side W2 in the vehicle width direction than the second joint row L2, and the first joint row L1 and the second joint row L2 are arranged in the vehicle width direction. The side panel outer panel vertical wall 8T1 (see FIG. 5) on the roof panel 5 side is located therebetween. As a result, as shown in FIG. 6, the portion other than the flange 6F1 of the roof side inner rail 6 can be disposed on the outer side W2 in the vehicle width direction (the two-dot chain line indicates the position of the roof side inner rail 6 having the structure of the comparative example). Is shown). Therefore, the head clearance A in the vehicle compartment can be increased without reducing the width of the required side body and without reducing the rigidity of the side body. As a result, the obstacle value to the passenger's head 50 at the time of a side collision can be reduced.

図５に示すように、ルーフパネル５側のルーフサイドインナーレール縦壁６Ｔ１と、ルーフパネル５側のルーフサイドリンフォース縦壁７Ｔ１とは、ルーフサイドインナーレール６及びルーフサイドリンフォース７の幅方向において略同じ位置に位置する。さらに、ルーフサイドインナーレール６及びルーフサイドリンフォース７の幅方向において、第１接合部列Ｌ１が、ルーフパネル５側のルーフサイドインナーレール縦壁６Ｔ１及びルーフパネル５側のルーフサイドリンフォース縦壁７Ｔ１の近傍に位置している。   As shown in FIG. 5, the roof side inner rail vertical wall 6T1 on the roof panel 5 side and the roof side reinforcement vertical wall 7T1 on the roof panel 5 side are the width direction of the roof side inner rail 6 and the roof side reinforcement 7 Are located at substantially the same position. Furthermore, in the width direction of the roof side inner rail 6 and the roof side reinforcement 7, the first joint portion row L1 includes the roof side inner rail vertical wall 6T1 on the roof panel 5 side and the roof side reinforcement vertical wall on the roof panel 5 side. It is located in the vicinity of 7T1.

これにより、ルーフサイドインナーレール６とルーフサイドリンフォース７によって形成される閉じ断面の剛性が向上し、衝突時のサイドボディの変形をより確実に抑えることができる。   Thereby, the rigidity of the closed cross section formed by the roof side inner rail 6 and the roof side reinforcement 7 is improved, and the deformation of the side body at the time of a collision can be more reliably suppressed.

本発明の構造についてさらに説明する。図３，図５に示すように、ルーフパネル５側のルーフサイドインナーレール縦壁６Ｔ１は、ルーフパネル５側のサイドボディアウターパネル縦壁８Ｔ１に対し、車幅方向外側Ｗ２（詳しくは車幅方向外側下方）に位置する。また、第１接合部列Ｌ１は、ルーフパネル５側のサイドボディアウターパネル縦壁８Ｔ１と、ルーフパネル５側のルーフサイドインナーレール縦壁６Ｔ１（及びルーフパネル５側のルーフサイドリンフォース縦壁７Ｔ１）との間に位置する。そして、第１接合部列Ｌ１は、サイドボディアウターパネル８とルーフサイドインナーレール６によって形成される閉じ断面の内側に位置する。さらに、前記第１接合部２１と第２接合部２２は車両前後方向において交互に位置して、複数の第１接合部２１と複数の第２接合部２２が千鳥状に位置している。   The structure of the present invention will be further described.
