本考案は自動車のアンダーボデイ構造に関し、
詳しくは塗装時に必要なメンバ内のエア抜き構造
に関するものである。[Detailed description of the invention] (Industrial application field) The invention relates to the underbody structure of automobiles.
More specifically, it relates to the air venting structure inside the member, which is necessary during painting.

できる。(Function) According to the present invention, the concave portion formed in the flange portion of the first member allows the first member and the second member to
This allows air to circulate between members, and air moves from the member with poor air release to the member with good air release during electrodeposition coating, so if you form an air release structure such as an air release hole on only one member, good.
In addition, members that do not require an air bleed structure do not allow mud, water, etc. to directly intrude inside them. Therefore, the underbody structure of the present invention has fewer air bleed holes and grommets than the conventional example. This makes it possible to reduce costs.

ものである。(Embodiment) In the embodiment shown in the drawings, the end of a cross member (second member) 2 having an inverted hat cross section is spot welded to the side surface of a side member (first member) 1 having an inverted hat cross section. The present invention is applied to a structure in which the upper surfaces of the side members 1 and cross members 2 are joined to the floor panel 3.
