A headrest device (10, 50) comprising: a headrest stay (16, 16') that is coupled to an upper end portion of a seatback (14) of a vehicle seat (12), and that supports a headrest pad (18); an internal structure (22) that is embedded inside the headrest pad, that is supported from a rear by the headrest stay, and that supports a head (H) of an occupant (24) from the rear during a vehicle rear-on collision via a support face (22A) that is formed at a front face of the internal structure; and a forward projection portion (17, 52) that is configured by a portion of the headrest stay that projects forward, that is disposed at an upper side or a lower side of the support face (22A) within the headrest pad (18), and that reduces or eliminates tilting backward or tilting forward of the head (H) supported by the support face, by pivoting about the support face as a pivoting centre. |
