Claim Text:
1. A headrest device comprising: a headrest stay that is coupled to an upper end portion of a seatback of a vehicle seat, and that supports a headrest pad; an internal structure that is made of foam, that is embedded inside the headrest pad, and that is supported from a rear by the headrest stay, the internal structure having a support face facing a vehicle front direction when the seatback is in an upright position so as to support the head of the occupant from the rear during a vehicle rear-on collision; and a forward projection portion that is configured by a portion of the headrest stay that projects in the vehicle front direction above the internal structure, and that suppresses the head supported by the support face from tilting backward, which is caused by the head by pivoting about the support face as a pivoting center, wherein a front end portion of the forward projection portion projects further in the vehicle front direction than the entire support face of the internal structure when the seatback is in the upright position, and the forward projection portion is a same rigid body as the headrest stay.
