With respect to the reinforcement member 16, the position of the reinforcement member 16 on the outer side in the vehicle width direction of the vehicle is located on the outer side in the vehicle width direction of the vehicle with respect to the center pillar 14. Specifically, the 7 th plate portion 160, the 8 th plate portion 161, and the 9 th plate portion 162 are positioned outside the 4 th plate portion 140 in the vehicle width direction of the vehicle. The 10 th plate portion 163 is located outside the 6 th plate portion 142 in the vehicle width direction of the vehicle. The reinforcing member 16 is attached to the center pillar 14 so as to be positioned on the outer side in the vehicle width direction of the vehicle, whereby the bent portion of the center pillar 14 is covered. As a result, the reinforcing member 16 can cover the gap existing between the lower end of the roof pillar 11 and the upper portion of the center pillar 14.
The lower end of the top pillar 11 is located above the upper end of the reinforcing member 16. Further, with respect to the reinforcement member 16, the position of the reinforcement member 16 on the outer side in the vehicle width direction of the vehicle is located on the outer side than the position of the roof pillar 11 on the outer side in the vehicle width direction of the vehicle. Specifically, the 1 st plate portion 110 of the top pillar 11 is located above the 7 th plate portion 160 of the reinforcing member 16. Therefore, the vicinity of the outer ends of the 2 nd plate portion 111 and the 3 rd plate portion 112 in the vehicle width direction of the vehicle is located above the 7 th plate portion 160 of the reinforcing member 16. Further, the vicinity of the inner ends of the 2 nd plate portion 111 and the 3 rd plate portion 112 in the vehicle width direction of the vehicle is located above the 4 th plate portion 140 of the center pillar 14.
The bracket 17 connects the head pillar 11 and the center pillar 14. The bracket 17 is fixed to the center pillar 14 by inserting a bolt into a hole formed below the bracket 17 and a hole formed in the center pillar 14, and tightening a nut to the inserted bolt. The bracket 17 is fixed to the head post 11 by inserting a bolt into a hole formed above the bracket 17 and a hole formed in the head post 11, and tightening a nut to the inserted bolt.

The 7 th plate portion 160a is a plate portion extending in the front-rear direction of the vehicle, similarly to the 7 th plate portion 160. Like the 8 th plate portion 161, the 8 th plate portion 161a is a plate portion extending inward in the vehicle width direction of the vehicle from the end portion of the 7 th plate portion 160a on the front side in the vehicle front-rear direction. The 9 th plate portion 162a is a plate portion that extends forward in the vehicle longitudinal direction from the end portion of the 8 th plate portion 161a on the inner side in the vehicle width direction, as in the 9 th plate portion 162.
Like the 10 th plate portion 163, the 10 th plate portion 163a is a plate portion extending inward in the vehicle width direction of the vehicle from the end portion of the 7 th plate portion 160a on the rear side in the vehicle front-rear direction. The 11 th plate portion 164a is a plate portion formed at the upper end in the longitudinal direction of the 7 th plate portion 160a, the 8 th plate portion 161a, the 9 th plate portion 162a, and the 10 th plate portion 163a so as to be orthogonal to the 7 th plate portion 160a, the 8 th plate portion 161a, the 9 th plate portion 162a, and the 10 th plate portion 163 a.
In the reinforcing structure 1a of the roof of embodiment 2, the lower end portion of the roof pillar 11 is positioned above the 11 th plate portion 164 a. In this way, the reinforcing member 16a of the reinforcing structure 1a for a roof of embodiment 2 includes the 11 th plate portion 164 a. As a result, in the roof reinforcement structure 1a, even if a load is applied to the roof 10 from above, the roof pillar 11 is supported by the reinforcement member 16a, so that deformation of the vehicle body due to downward movement of the roof pillar 11 can be suppressed.
Although the present invention has been described above by using the embodiments, the scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various changes and modifications can be made in the above embodiments. As is apparent from the description of the claims, the present invention can include such modifications and improvements within the scope of the present invention.
