CONSTITUTION: A side of a closed section of an aluminum space frame(3) of a front side member(2) is cut to form the space part, and a steel nut structure(4) with a bolting hole(5) is inserted to the closed section through the space part. A cover part(6) is made of the same material as material of the aluminum space frame and composed of a hole(7) penetrated by the bolt. The space part of the closed section is molten and finished by the cover part. Two or more sides of the nut structure are contacted and supported in the closed section, and the nut structure is inserted to the closed section and fastened by a bonding unit.
