示されている）。2. Description of the Related Art An example of a vehicle suspension mounting structure is shown in FIG. In the figure, the cross member 1 is formed in a hat-shaped cross section by press molding, and an insertion hole 3 for the suspension bolt 2 is formed in the bottom wall 1a thereof. Inside the cross member 1, a lower reinforcement 4 having a U-shaped cross section along the inner wall of the cross member 1 is joined. The head of the suspension bolt 2 is attached to the upper portion of the lower reinforcement 4. An upper reinforcement 5, which is supported and fixed to the upper part of the inner wall of the lower reinforcement 4, is attached. Then, the lower end of the suspension bolt 2 fixed in a state of penetrating the upper reinforcement 5 and the lower reinforcement 4 is attached to the insertion hole 3 of the bottom wall 1 a of the cross member 1.
The suspension is supported here (this structure is disclosed in Japanese Patent Laid-Open No. 3-28009).

る。In the above-mentioned conventional suspension mounting structure, the input load to the suspension bolt 2 can be effectively transmitted to the cross member 1 by the upper reinforcement 5 and the lower reinforcement 4. Although it is possible, since the upper reinforcement 5 and the lower reinforcement 4 are inserted into the inside of the cross member 1 and attached, for example, when the cross member 1 is made of an extruded material having a closed cross-section structure, It is impossible to adopt a different structure. For example, when a lightweight and highly rigid vehicle body is required to support the weight of a battery like an electric vehicle, it is considered to employ a cross member 1 made of an extruded aluminum material. In the cross member 1, the upper reinforcement 5 and the lower reinforcement 4 cannot be inserted as they are, so that the suspension bolt 2 cannot be dropped into the cross member 1.
