Abstract: A vehicle seat that can suppress damage to an on-board object is provided. In each side frame of a cushion frame, an eccentric portion is eccentric outward in a right-left direction with respect to a base portion, and in each side frame of a back frame, an eccentric portion is eccentric inward in the right-left direction with respect to a base portion. Thus, when the load at the time of rear collision acts, each side frame of the cushion frame easily becomes deformed outward in the right-left direction, and each side frame of the back frame easily becomes deformed inward in the right-left direction. Accordingly, the deformation direction of each side frame of the cushion frame and the deformation direction of each side frame of the back frame can be easily made opposite to each other, and the deformations of the respective side frames and can be inhibited.
