FIG. 4 is a cross-sectional view of the roof side portion 108 in FIG. 2(a). FIG. 4(a) is an AA sectional view of the roof side portion 108 in the vicinity above the rear pillar 116 in FIG. 2(a).

The roof side portion 108 is formed to include a vertical wall portion 132 extending in the vertical direction and a curved portion 134 extending in a curved manner from the vertical wall portion 132. The vertical wall portion 132 is formed to face outward in the vehicle width direction, and forms a side surface of the vehicle 102 (see FIG. 1). The curved portion 134 extends from the top of the vertical wall portion 132 toward the roof panel 106 of the vehicle 102 in a curved manner inward in the vehicle width direction.

Furthermore, a joint portion 136 that is joined to the side edge of the roof panel 106 (see FIG. 1) is provided on the inside of the roof side portion 108 in the vehicle width direction.

The groove-shaped portion 130 (rear end region 130b) is formed by recessing a predetermined portion of the curved portion 134. For example, the rear end region 130b of the groove-shaped portion 130 is a range on the outer side of the vehicle that divides the curved portion 134 into two in the vehicle width direction, and is located at a position slightly closer to the center P1 of the curved portion 134 than the vertical wall portion 132. It is formed.

FIG. 4(b) is a BB cross-sectional view of the roof side portion 108 in FIG. 2(a) near the rear side of the center pillar 112. The intermediate region 130c of the groove-shaped portion 130 is formed in the outer side range of the curved portion 134 divided into two in the vehicle width direction, and is formed at a position slightly closer to the center portion P1 of the curved portion 134.

FIG. 4(c) is a CC sectional view of the roof side portion 108 in FIG. 2(a) near the upper part of the front pillar 110. The front end region 130a of the groove-shaped portion 130 is also formed in the outer side range of the curved portion 134 divided into two in the vehicle width direction. However, compared to the rear end region 130b in FIG. 4(a) and the intermediate region 130c in FIG. 4(b), the rear end region 130b in FIG. is formed.

As described above, the front end region 130a is formed closer to the vertical wall portion 132 than the intermediate region 130c and the rear end region 130b of the groove-shaped portion 130 that are rearward of the front pillar 110. Therefore, as shown in FIG. 2(a), for example, the front end region 130a of the groove-shaped portion 130 extends downward and forward while being slightly curved so as to gradually move downward toward the front above the front pillar 110. ing.

As described above, the front end region 130a is located slightly lower than the intermediate region 130c and the rear end region 130b. In this way, the position of the groove-shaped portion 130 on the curved portion 134 of the roof side portion 108 changes in the longitudinal direction of the vehicle, thereby making it possible to make the curved portion 134 more difficult to bend and improve its rigidity. It has become. In particular, by changing the position of the groove-shaped portion 130 near the front end region 130a, it is possible to ensure rigidity even in the narrow front end region 130a.

Referring again to FIG. The maximum width W2 of the rear end region 130b in FIG. 3(b) is set to be wider than the maximum width W1 of the front end region 130a in FIG. 3(a) (W2>W1). In this way, the groove-shaped portion 130 is set so that the width changes in the vehicle longitudinal direction.

As described above, according to the vehicle roof side structure 100, the groove-shaped portion 130 is provided in the curved portion 134 to increase the moment of inertia of the area, thereby making the curved portion 134 difficult to bend and improving its rigidity. This makes it possible to prevent deformation of the curved portion 134.

Further, the groove-shaped portion 130 is formed so that both the front end region 130a and the rear end region 130b are tapered, and the rear end region 130b is wider than the front end region 130a, so that There are changes in shape. Therefore, the groove-shaped portion 130 absorbs the load by changing its shape, making it easier to suppress deformation of the curved portion 134. Therefore, according to the roof side structure 100 for a vehicle, it is possible to improve both the aesthetic appearance and the rigidity of the roof side portion 108 of the vehicle 102 with a simple structure in which the groove-shaped portion 130 is provided.

Referring again to FIG. The tapered front end portion 138 formed from the maximum width W1 of the front end region 130a in FIG. 3(a) to the tip is tapered from the maximum width W2 of the rear end region 130b in FIG. It is set longer than the tapered rear end taper portion 140 that is formed. That is, the front end tapered portion 138 has a taper ratio ((D-d)/L), which is the ratio between a wide portion (large diameter D) and a narrow portion (small diameter d) separated by a predetermined distance L. , is set smaller than the rear end tapered portion 140.

In the above configuration as well, the aesthetic appearance of the roof side portion 108 is improved, and by changing the shape of the groove-shaped portion 130 in the longitudinal direction of the vehicle, the rigidity of the curved portion 134 can be improved and its deformation can be further suppressed. It becomes possible.

In this embodiment, the taper ratio of the front end tapered part 138 is set smaller than the taper ratio of the rear end taper part 140; It is also possible to set the taper ratio smaller than 138. In addition, it is also possible to make only one of the front end region 130a and the rear end region 130b tapered. With these configurations as well, it is possible to change the shape of the groove-shaped portion 130 in the longitudinal direction of the vehicle.

Further, in the present embodiment, the maximum width W2 of the rear end region 130b is set to be wider than the maximum width W1 of the front end region 130a, but as a reverse configuration, the maximum width W1 of the front end region 130a is set to be wider than the maximum width W1 of the front end region 130a. It is also possible to set the width to be wider than the maximum width W2 of the end region 130b (W1>W2). With this configuration as well, it is possible to change the shape of the groove-shaped portion 130 in the longitudinal direction of the vehicle.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that those skilled in the art can come up with various changes and modifications within the scope of the claims, and these naturally fall within the technical scope of the present invention.
