The roof rail 4 of the left and right sides in portion 1 and respectively positioned at vehicle body upper portion 1 rear ends at roof front-axle beam 5 and roof after
The periphery of beam 6, and resin roof 2 is arranged in the whole region of vehicle body upper portion 1.Roof rail 4 is along vehicle fore-and-aft direction
Linearly extend, and be arranged parallel to each other at predetermined intervals in the respective position of the left and right sides of vehicle body upper portion 1.
The roof 2 of present embodiment be not limited to be formed from a resin or made of steel rather than resin plate shape into or by such as
Plate shape made of the alloy in lightweight of aluminium etc. into.
As shown in figure 1, the roof cross beam 3 of present embodiment have can frame between the roof rail 4 of the left and right sides
Length, and roof cross beam 3 in the vehicle width direction there is heterochiral end 3a, heterochiral end 3a to lead to respectively
Cross spot welding etc. and be connected to a roof rail 4.It is connected in addition, roof cross beam 3 is arranged in central post 7 on vehicle fore-and-aft direction
The opening position of roof rail 4.Central post 7 extends along vehicle above-below direction and with the upper end for being connected to roof rail 4.
In addition, roof cross beam 3 is formed as the shape with substantially hat (hat-shaped) section, and has and be arranged in
The opening portion of vehicle lower side or vehicle upper side.Roof cross beam 3 includes upper surface portion 31 and the front and back position positioned at the upper surface portion 31
Flange part 32.
In the structure according to the vehicle body upper portion 1 of present embodiment, as shown in figure 1, roof cross beam 3 and roof rail 4 are logical
Cross corresponding first enhancing component 8 to connect, each first enhancing component 8 is arranged to from positioned at the vehicle width side of roof cross beam 3
Indulged to the pars intermedia near central portion along incline direction to a roof corresponding in the roof rail 4 of the left and right sides
Beam 4 extends.First enhancing component 8 is arranged in vehicle front side region R1 and rear view of vehicle side region R2 by twos.Car
Front side region R1 is the region surrounded by roof cross beam 3, roof front-axle beam 5 and roof rail 4 positioned at the left and right sides.Vehicle
Rear side region R2 is the region surrounded by roof cross beam 3, the roof back rest 6 and roof rail 4 positioned at the left and right sides.
First enhancing component 8 can be arranged at least one of vehicle front side region R1 and rear view of vehicle side region R2
In, without all being arranged in two regions R1 and R2.
Each first enhancing component 8 of the vehicle front side region R1 left and right sides is arranged in the vehicle from roof cross beam 3
Towards vehicle while width central portion extends about roof rail 4 in the roof rail 4 of the left and right sides
Front extends.The interval that first enhancing component 8 is arranged on the vehicle-width direction of base end part 8a sides is less than terminal part 8b sides
Interval on vehicle-width direction.Each first enhancing component 8 of the rear view of vehicle side region R2 left and right sides is arranged in from car
The vehicle-width direction central portion of head piece 3 extends about a roof rail 4 in the roof rail 4 of the left and right sides
