VEHICLE SEAT

A seat back pad has a groove for tucking a skin material therein, formed at borders between a central portion and side portions . A hole (slot hole ) is formed in a bottom of the groove along the groove . A tuck-in wire for tucking the skin material in includes a plurality of tuck-in portions A provided along the groove , and a connecting portion (detour portion B) detouring around the hole and connecting the tuck-in portions A. With this configuration, when an upper body of an occupant P subsides into a seat back S in a rear-end collision of a vehicle, the central portion , defined by the groove as a border, is easily and sufficiently moved rearward relative to the left and right side portions Furthermore, the tuck-in wire is not exposed through the hole, and thus adhesion between the seat back pad and the tuck-in wire can be improved.
