The present invention provides a seatback S-spring attachment structure which makes it possible to simplify the structure of a seatback frame (7) and decrease the weight thereof. An S-spring member (10) has left and right end sections (10a, 10b) containing curved sections (10aU, 10bU). In addition, attachment sections (11) for attaching the left and right end sections (10a, 10b) of the S-spring member (10) are formed in each outside lateral surface section of left and right cylindrical sideframe sections (9L, 9R) of the seatback frame (7). The attachment sections (11) are formed as hole sections (11A-1, 11A-2), the S-spring member curved sections (10aU, 10bU) are tightly adhered along the outer-circumferential surface of the left and right cylindrical sideframe sections (9L, 9R), and the tip end sections (10aE, 10bE) of the left and right end sections (10a, 10b) are inserted into the hole sections (11A-1, 11A-2) and fastened thereto.
