body side structure

Abstract

Disclosed is a structure for a side portion of a vehicle body, the structure being configured in such a manner that the ends of an arch member (18) are mounted to rail members (15) extending in the front-rear direction of the vehicle body and that a roof panel (20) is supported by the arch member. The structure (10) for a side portion of a vehicle body is provided with: the rail members (15); the arch member (18) which extends in the width direction of the vehicle and the ends of which are mounted to the rail members (15); and the roof panel (20) supported by the arch member. In each of the rail members (15), an outer extension section (33) is integrally provided to a rail outer section (32) and an inner extension section (37) is integrally provided to a rail inner section (36). The arch member (18) is provided with an arch upper member (62) which can be installed on the outer extension section (33) and an arch lower member (72) which can be installed on the inner extension section (37).

Description

technical field [0001] The present invention relates to a vehicle body side structure in which roof side rails (stringer members) extend in the front-to-rear direction above the vehicle body side, and the ends of the roof rails (arch members) are provided with On the side member, the roof panel is supported on the arch member. Background technique [0002] Such a body side structure is known as disclosed in JP 2003-118634 A. In this side structure of the vehicle body, since the side member outer member (pillar reinforcement) is superimposed on part of the side member inner member (inner panel) which becomes the inner wall of the side member member from the vehicle body outside, the side member member (side member inner panel) members and pillar reinforcements) are formed in a closed section, and the arch member is provided on and intersects with the side member of the closed section toward the vehicle width direction. A roof panel is provided above the arch member, and the...

Problems solved by technology

[0005] However, due to the influence of forming tolerances and assembly tolerances of the inner and outer members of the longitudinal beam, it is difficult to assemble the inner panel and the pillar reinforcement at the boundary with high precision.

Therefore, when the flange of the roof panel is welded to the two members of the inner panel and the pillar reinforcement across the boundary portion, it is difficult to position the roof panel with high precision.
