PROBLEM TO BE SOLVED: To provide a reinforcing structure capable of effectively preventing bending deformation of a cross-sectional shape, in a vehicle seat frame.SOLUTION: A seat back frame 10 (vehicle seat frame) includes a pair of right and left side frames 11 and is configured such that each of the side frames 11 is formed to have a cross-sectional shape including a side surface part 11A facing a seat width direction and a rear surface part 11C bent from the side surface part 11A to the seat inside. The seat back frame 10 includes a bridging frame 13 that is provided stretched over in the seat width direction between the respective side frames 11 and integrally connects the respective side frames 11 to each other. The bridging frame 13 is provided integrally joined to each of the side surface part 11A and the rear surface part 11C respectively formed in each of the side frames 11, and is configured to allow the bridging frame 13 to prevent movement of being bent in a bending direction which is generated between the side surface part 11A and the rear surface part 11C. |
