2. Description of the Related Art A side panel of a vehicle A, particularly a center pillar 1, shown in FIG. 9 has a closed sectional space formed by an outer panel 2 and an inner panel 3 as shown in FIG. An opening 6 into which the main body 5 of the seat belt retractor 4 for rewinding the seat belt 4a can be inserted is formed. As shown in FIG. 10, a supporting portion 8 is formed on the lower edge 6 a of the opening 6 so that the mounting portion 7 of the seat belt retractor 4 can be fastened and supported by bolts 9 and nuts 10. As a technique, see Japanese Utility Model Laid-Open No. 1-15585) and FIG.
As shown in FIG. 1, the outer panel 2 and the inner panel 3 form a closed sectional space, and the inner panel 3 has the same shape until the opening 6 through which the main body 5 of the seat belt retractor 4 can be inserted is formed. The bracket 11 is supported by the welding SW so as to reach the inside of the opening 6 from the lower edge 6 a of the opening 6, and the claws 12, 12 protruding from the bracket 11 are used to secure the seat belt. Some of the retractors 4 are supported so that the mounting portion 7 of the retractor 4 is prevented from turning back and forth. Reference numeral 13 denotes the bracket 11
This is a reinforcing bead formed on the substrate.

[0003]

However, in such a conventional technique, there is no provisional holding means for the seat belt retractor 4 in the former, so that the main body of the seat belt retractor 4 is held by one hand. Hold 5 and bolt 9
While holding it in the through hole of the support portion 8 while holding the nut 10 with another hand and temporarily screwing it into the bolt 9 with a finger, and holding the tool placed on the floor or the like by holding the nut 10 It is necessary to work to firmly secure That is, such work is complicated, such as temporarily fixing the nut 10 with a finger or holding a fastening tool, and it is required to further improve workability. Further, it is necessary to increase the thickness of the inner panel 3 in order to increase the rigidity of the inner panel 3 itself so as to withstand an impact load applied to the seat belt retractor 4. Immediately linked to the increase, improvements are required in terms of improving fuel efficiency.

[0004] In the latter case, the pawls 12, 12 for stopping rotation of the main body 5 of the seat belt retractor 4 protrude toward the indoor side. There is a problem that work is difficult. In addition, beads 13 are required to improve the rigidity of the bracket 11, and the molding die cannot be formed by a simple bending die, but becomes a drawing die. In this respect, improvement is also required.

The present invention has been made in view of such prior art, and has as its object to provide a vehicle side panel structure which achieves weight reduction and cost reduction and significantly improves workability. And
