PROBLEM TO BE SOLVED: To reduce the weight of a seat frame reinforcing structure without hindering the reinforcing performance. SOLUTION: This seat frame reinforcing structure includes a reinforcing member Re longitudinally extending in a direction between both side frames 10A and 10B forming a framework of the seat back of a vehicle seat. The reinforcing member Re is structured by combining: a rod 50 formed larger in diameter than operating pins 37A and 62B to be inserted into the center parts of each reclining device 30A and 30B; bushes 60A and 60B joined with both ends of the rod 50; and a guide member 70A provided by integrally joining to a side frame 10A so as to cover the operating pin 37A exposed in a gap formed between the end of the one bush 60A and the side frame 10A of the seat back from a peripheral side. The guide member 70A covers the operating pin 37A exposed in the gap from the peripheral side to practically form this part large in diameter. COPYRIGHT: (C)2011,JPO&INPIT
