Abstract

Provided is a headrest that is capable of improving the rigidity of a headrest frame and preventing the leakage of a foaming agent upon integral foam formation of the headrest. The headrest, which is disposed on the upper part of a seatback and includes a headrest frame inside the headrest, includes a retaining portion of a headrest stay guide in the headrest frame. Further, the headrest is configured in a manner that a headrest skin is sandwiched between the headrest stay guide and the headrest frame.
