PROBLEM TO BE SOLVED: To provide a vehicular seat capable of effectively reducing impact applied to an occupant in a rear collision independently of a headrest, by increasing a sinking-in (moving) distance of the body to the seat back side in the rear collision. SOLUTION: This vehicular seat S has a seat back frame 1, a headrest S3, a pressure receiving member 20 movable independently of the headrest S3 and a rotary member 30 arranged on at least one side in a side part on both sides of the seat back frame 1. Though the rotary member 30 can move by a predetermined impact load independently of the headrest S3, the rotary member 30 is connected to an energizing means 35 for energizing the pressure receiving member 20 to the front side of the seat back frame 1 via connecting members 21 and 22, and is constituted so as to include a range where force for returning the rotary member 30 to an initial state becomes largest in ordinary sitting and becomes small when the rotary member 30 can move by the rear collision.
