汽车的车顶结构
摘要：
本发明提供一种可使顶盖弧拱的成本及重量降低并可确保宽敞的车厢内空间的汽车车顶结构。顶盖弧拱(4)只与顶板(3)的车顶部(20)接合。即，因为无需设置沿顶板(3)的壁部(21)的内面弯折并与侧上边梁(2)接合的部分，因而可使顶盖弧拱(4)小型化。另外，通过在顶板(3)的壁部(21)上形成略凸形状的突出部(23)，而可使顶盖弧拱(4)只与顶板(3)的车顶部(20)接合的结构中不足的强度得到补充，可确保与顶盖弧拱接合在侧上边梁(2)时同等的强度。而且，通过使在顶板(3)的壁部(21)上形成的突出部(23)朝车宽方向外侧突出，就可在顶板(3)的壁部(21)的内面上的区域形成沿汽车前后方向连续的空间。
摘要（英）：

To provide a roof structure for an automobile capable of reducing the cost and weight of a roof bow, and securing a large cabin space. The roof bow 4 is joined only to the roof part 20 of a roof panel 3. That is, it is not necessary to provide a part bent along the inner face of the wall part 21 of the roof panel 3 and joined to a side roof rail 2 in the roof bow 4, therefore, the roof bow 4 canbe miniaturized. Furthermore, a protruded part 23 nearly in a projecting shape is formed in the wall part 21 of the roof panel 3. Thus, strength insufficient in a structure where the roof bow 4 is joined only to the roof part 20 of the roof panel 3 is compensated, and strength equivalent to a case where the roof bow is joined to the side roof rail 2 can be secured. Moreover, the protruded part 23formed in the wall part 21 of the roof panel 3 is protruded to the outside in the vehicle width direction, and thus, a space continued along the vehicle longitudinal direction is formed in an area onthe inner face of the wall part 21 of the roof panel 3.
