い。As shown in FIG. 7, the web 1 has a web width A longer than the flange width B in order to secure rigidity when the closed cross-section 1a of the base material 1 is formed into a seat back frame 2. The front end of the first flange portion 1b may be hemmed so as not to cause a cut or the like on a back cushion or a back skin (not shown) supported by the seat back 2. It may be an arc shape. As shown in FIG.
The cross-sectional shape of the flange portion 1b is
It is good also as a cross-sectional shape which becomes the mounting recessed part of the reclining mechanism 4 at the time of the above. As shown in FIGS. 9 and 10, the cross-sectional shape of the second flange portion 1c may be such that the hook portion 2c when the seat back frame 2 is formed has a shape directed downward and laterally.

２として容易に構成される。As described above, the seat back frame 2
Has an integral hook portion 2c for locking the spring 5. As a result, the number of parts and the number of joints are reduced as compared with the conventional case, and the number of assembly steps such as control of welding strength and quality is greatly reduced. Further, there is no deformation when the hook portion 2c is integrated with the seat back frame 2, and there is no need to adjust the position of the hook portion 2c. Therefore, the number of assembling steps is further reduced. Further, since the base material 1 constituting the seat back frame 2 is roll-formed, it can be easily configured as a seat back frame 2 having an arbitrary shape in consideration of the strength, the mounting direction of the spring 5, and the like.
