Abstract
Load imparted to a seat back frame is stably absorbed and efficiently absorbed. In a vehicle seat, a weak portionis formed by a fixing plate (). The weak portion () continuously extends from an edge portion of a fixing hole () in the relative movement direction with respect to a hinge base bracket () of a fastening bolt. Thus the weak portion () presses against the fastening bolt when the hinge base bracket () rotationally moves about the axial line of a support hole (). Moreover, when the weak portion () plastically deforms, deformation so as to press the weak portion () wider is suppressed, such that the weak portion () is deformed so as to be squashed. Consequently, load imparted to a seatback frame () can be stably absorbed by the weak portion (). Moreover, due to the weak portion () continuously plastically deforming when the weak portion () is plastically deformed by the fastening bolt, the load imparted by the weak portion () to the seatback frame () can be efficiently absorbed.
