A seat back frame includes an upper frame member that forms an upper side, a reinforcing member that is provided parallel to and below the upper frame member, and a headrest mounting member, that overlaps with both the upper frame member and the reinforcing member. The headrest mounting member is arranged such that, in one location, from among a location where the headrest mounting member overlaps with the upper frame member and a location where the headrest mounting member overlaps with the reinforcing member, the headrest mounting member is fixed to one of the upper frame member and the reinforcing member, and in the other location, the headrest mounting member abuts against the other of the upper frame member and the reinforcing member when the headrest tilts rearward about the one location, such that the tilting of the headrest is inhibited.
