DETAILED DESCRIPTION OF THE INVENTION Hereinafter, will be described with reference to FIG. An embodiment of the present invention. FIG. 1 is a perspective view showing a roof panel 1 according to the present embodiment. The roof panel 1 has a first opening 2 of a front sunroof and a second opening of a rear sunroof on the front F side of the vehicle. An opening 3 is provided. [0011] The roof panel 1, the first and second
A front region 11 forming a front F side of the vehicle in which the openings 2 and 3 are formed, and a rear region 12 forming a rear R side of the vehicle from the front region 11, and the front region 11 expands upward. It is formed in a projected spherical shape. The front area 1
1, when a curved ridge line extending in the vehicle front-rear direction is imagined as a first camber line 13, and a curved ridge line extending in the vehicle width direction is imagined as a second camber line 14, First and second camber lines 13, 14
Is a central portion 1 between the first and second openings 2 and 3.
5 so as to intersect. The rear region 12 is formed in a substantially planar shape, and a curved surface and a flat surface are connected between the front region 11 and the rear region 12, as shown in FIG. The correlation line 21 is formed along the vehicle width direction. The correlation line 21 is formed in a circular arc shape whose central portion bulges toward the rear R side of the vehicle, whereby the roof panel 1 has an increased refraction intensity on the correlation line 21. The rear region 12 has first to fourth bulges bulging out of the general portion 31 in the rear region 12.
Are extended in the vehicle front-rear direction. The front ends of the beads 32 to 35 are connected to the front region 11 formed in a spherical shape, and the beads 32 to 35
5 is formed integrally with the front region 11. The first and second beads 32, 33 are formed on the left side with respect to the center of the vehicle, and the third and fourth beads 34, 33 are formed.
35 is formed on the right side with respect to the center of the vehicle,
The second and third beads 33 and 34 are formed behind the second opening 3. In this embodiment having the above-described structure, as shown in FIG. 3, the first opening 2 of the front sunroof and the second opening 3 of the rear sunroof are located on the front F side of the vehicle. The front region 11 is formed in a spherical shape that bulges upward, so that the tensile rigidity is enhanced and the peripheral edges of the first and second openings 2 and 3 are reinforced. For this reason, even when snow accumulates in the front area 11, the strength against the snow can be increased. Further, by swelling the front area 11 in which the sunroof is provided upward, the arrangement spaces 43 and 44 in which the front sunroof unit 41 and the rear sunroof unit 42 are disposed can also be secured. Compared with the conventional case in which the front area of the installed roof panel is formed in a flat shape, the headroom 46 in the vehicle interior 45, that is, the occupants 47,
47 can be enlarged. As shown in FIGS. 1 and 2, the first to fourth beads 32 to 35 projecting upward from the general portion 31 in the rear area 12 on the vehicle rear R side of the front area 11. Accordingly, the rigidity can be increased, and the second and third beads 33 and 34 are formed behind the second opening 3, so that the beads 33 and 34 are located behind the second opening 3. The rigidity behind the opening 3 can be increased as compared with a conventional roof panel in which the roof panel 34 is not formed. [0016] Accordingly, without forming the roof panel 1 in thick, it is possible to increase the rigidity of the roof panel 1 whole, compared with the case of forming the roof panel 1 in thick, lightweight roof panel 1 Can be achieved. Furthermore, the front region 11 formed in a spherical shape
And the correlation line 21 extending between the flat region and the rear region 12 is formed in an arc shape bulging rearward, and the beads 32 are formed from the front region 11.
Since .about.35 are integrally extended, the refraction intensity on the correlation line 21 can be increased. This allows
In upon delivery of the roof panel 1, the can be prevented in advance Re inadvertent folding of the roof panel 1 in the correlation line 21 parts, it is possible to improve the productivity. [0018] In the roof panel of the present invention as described in the foregoing, in the front region of the vehicle front side of the opening of the sunroof is provided, formed in a spherical shape that bulges to said front region upward By doing so, the tension rigidity can be increased, so that the strength at the time of snowfall can be increased. In addition, by swelling the front area where the sunroof is provided upward, it is possible to secure a space in which the sunroof unit is provided. As a result, it is possible to increase the headroom in the vehicle cabin. In the rear region on the vehicle rear side of the front region, rigidity can be increased by a plurality of beads projecting upward from the general portion, and these beads are formed behind the opening. Therefore, the rigidity behind the opening can be increased as compared with a conventional roof panel in which no bead is formed behind the opening. Therefore, the rigidity of the entire roof panel can be increased without forming the roof panel with a large thickness, and the weight of the roof panel can be reduced as compared with the case where the roof panel is formed with a large thickness. Furthermore, the correlation line extending between the spherically formed front region and rear region, as well are formed in an arc shape, the front region, said each bead upper surface
The front end is provided continuously . Therefore, the refraction intensity on the correlation line can be increased. Thus, when the roof panel is delivered, careless bending of the roof panel can be prevented, and productivity can be improved. [0021]
