Connecting structure

The invention provides a connecting structure which can improve the rigidity of a bending load acting on a T-shaped connecting part. In a connecting structure, a second part 20 is connected to a first part 10 to form a T-shape, wherein a first upper surface 11a and a flange 25 are connected together through the connecting parts 30a, 30b. First curved ribs 15a, 16a are arranged on the rear of the first upper surface 11a, separated and removed from the second part 20 with corners 22b, 23b as starting points, and then flex in a first direction and extend in the first direction. second curved ribs 15b, 16b and the first curved ribs 15a, 16a and are opposite. The first curved ribs 15a and 16a and the second curved ribs 15b, 16b cross each other at two points and define enclosed areas 15c, 16c. ; The enclosed areas 15c, 16c overlap with the connecting area of the connecting parts 30a, 30b. 本发明提供种接合结构。该接合结构能够提高相对于作用于T字形的接合部的弯曲载荷的刚性。该接合结构在第1构件(10)接合第2构件(20)，呈T字形状，第1上表面(11a)及凸缘25通过接合部(30a、30b)接合起来。第1弯曲肋(15a、16a)设置在第1上
