Abstract (en)
There is provided an integral structural member comprising a plate and a tubular body, in which the rigidity of connection between the two is high, and the firm connection is achieved. Further, there is provided a production method of producing it easily. Part of a cylindrical wall 3 of the tubular body 2 is defined by superposed walls 6 held in intimate contact with each other, and that the outermost one 5 of the superposed walls 6 is folded back to be integrally continuous with the plate 1. <IMAGE> <IMAGE>
