Zusammenfassung:	Provided is a seatback structure for a seatback provided with a lower seatback support and an upper seatback support pivotably connected to the upper end of the lower seatback support. An actuator (17) is fixedly secured to one of a pair lower side frames (6) of a seatback frame (F), and an output end (17a) of the actuator is configured to move linearly along a length of the lower side frame, and a link (25) is provided with an upper end pivotally connected to a part of a corresponding upper side frame (7) and a lower end pivotally connected to the output end of the actuator. The upper end portion of the lower side frame and the lower end portion of the corresponding upper side frame comprise plate members facing laterally each other in an overlying relationship, and at least partly interposing the link therebetween.
