[Purpose] To provide a sinuous spring mounting structure in a seat back, which can realize a lightweight and simplified structure of a seat back frame of the seat back. A sinuous spring or S-spring 10 used in the present invention has left and right end portions 10a and 10b which include two curved regions 10aU and 10bU, respectively. A seat back frame 7 includes left and right cylindrical side frame portions 9L and 9R. One spring mounting portion 11 for allowing the left end portion 10a of the S-spring 10 to be mounted thereto is formed in an outwardly-facing lateral surface area of the left cylindrical side frame portion 9L, whereas the other spring mounting portion 11 for allowing the right end portion 10b of the S-spring 10 to be mounted thereto is formed in an outwardly-facing lateral surface area of the right cylindrical side frame portion 9R. Those two spring mounting portions 11 may be embodied by first and second hole portions 11A-1 and 11A-2, respectively, for example, in which case, two distal ends 10aE and 10bE of the S-spring 10 may be inserted and hookingly secured in the first and second hole portions 11A-1 and 11A-2, respectively, such that the two curved regions 10aU and 10bU of the S-spring 10 are closely contacted on and along two outer circumferential surfaces of the left and right cylindrical side frame portions 9L and 9R, respectively.
