In addition, the lateral roof outer roof body portion 7a of the roof outer side panel 7 is bonded to the second foam fill edge portion 1b of the foam fill component 11 with the adhesion of the foam fill component 11. , or with the adhesive, while they overlap.

Action and effect.

As described above, in the roof side spar 10 according to the present embodiment, the foam filling component 11 is arranged at least in a space inside the first corner C1 in the lower region if the closed section, and the foam filling component 11 is bonded to the roof side interior panel 6 and the roof side exterior panel 7, and thus, the roof side spar 10 can be effectively reinforced by the foam filling component In particular, the rigidity of the edge portion 1d of the opening positioned in the side surface 1b of the vehicle chassis body 1 contributes to the torsional stiffness of the vehicle body, and the first corner key is the closer to the edge portion 1d of the opening 1c, as described above, in the closed section S, and thus, the foam filling component 11 positioned at least in space within the first corner can effectively increase the torsional rigidity of the vehicle body. In addition, the foam filling component 11 is lightweight, and thus, can suppress a weight increase of a vehicle. In other words, the roof side spar 10 according to the present embodiment can suppress an increase in the weight of a vehicle, to be reduced, and can effectively increase the torsional rigidity of a vehicle body.

In the roof side spar 10 according to the present embodiment, the foam filling component 11 is arranged in a space inside the first wedge cl, the first foam filling edge portion 11a of the foam filling component. 11 is bonded to the inner panel body portion 6a in the roof inner side panel 6, and the second foam fill edge portion 11b is bonded to the roof lateral exterior bodywork lower portion 7a in the roof outer side panel 7 As a result, a cross-sectional area of the foam filling component 11 can be effectively reduced. As a result, the weight of the foam filling component 11 can be effectively removed, and thus, a weight increase of a vehicle can be effectively suppressed.

In the roof side spar 10 according to the present embodiment, the periphery of the first corner cl in the lower region if the closed section S can be reliably reinforced within a range in which the length X3 of the first The foam filling edge portion 11a bonded to the inner panel body portion 6a is equal to or greater than approximately 1/2 of the length Y1 of the inner panel body portion 6a, and the length X4 of the second fiber pad portion 11b foam bonded to the lower lateral roof outer bodywork portion 7a is equal to or greater than approximately 1/2 of the length Y2 of the lower lateral roof outer bodywork portion 7a, in view along the direction in which the closed section S extends. On the other hand, an increase in weight of the foam filling component 11 can be suppressed within a range in which the length X3 of the first foam filling edge portion 11a bonded to the inner panel body portion 6a is equal to or less than approximately 2/3 of the length Y1 of the inner panel body portion 6a, and the length X4 of the second foam padding edge portion 11b bonded to the lower lateral roof outer body portion 7a is equal to or less than at approximately 2/3 of the length Y2 of the lower lateral roofwork outer portion 7a, in view along the direction in which the closed section S extends. Accordingly, adjusting the range, as described above, can suppress an increase in weight of the foam filling component 11, and can effectively strengthen the periphery of the first wedge in the lower region if the closed section . Therefore, a weight increase of a vehicle can be suppressed, and the torsional rigidity of a vehicle body can be effectively increased.

In the lateral roof spar 10 according to the present embodiment, when the lateral roof inner panel 6 and the lateral roof outer panel 7 are deformed in the case where the two foam filling components 11 are respectively arranged in correspondence with the front end section and the rear end section of the foot binding portion 2b, a stress caused by the deformation can be effectively dispersed at the foot 2 by means of the two foam filling components 11. Thus, the torsional rigidity of a vehicle body can be effectively increased.

In the roof side spar 10 according to the present embodiment, in the case where a maximum length of the foam filling component 11 in the longitudinal vehicle direction is less than a maximum length of the foam filling component 11 in the direction of width of vehicle, the weight of the foam filling component 11 can be further suppressed, and thus, a weight increase of a vehicle can be suppressed further.

Embodiments of the present invention have been described so far; however, the present invention is not limited to the above embodiments, and thus, the present invention may be modified or changed depending on its technical concept.
