PROBLEM TO BE SOLVED: To provide a seat for a vehicle capable of actuating a headrest quickly in the event of collision. SOLUTION: A headrest driving mechanism 70 installed in a seat back 12 is equipped with a long hole bracket 51 having a guide hole 50, a sliding member 58 movable along the guide hole 50 between the first and the second position, a pressure receiving member 67, an engaging member 75 having a hook part 81, and a tensile spring 77. The engaging member 75 has a hook part 81 which is able to restrain the sliding member 58 in the first position. The tensile spring 77 energizes the sliding member 58 toward the second position. When the occupant pushes the pressure receiving member 67 backward to cause the hook part 81 to be set off from the sliding member 58, the member 58 moves along the guide hole 50 toward the second position owing to the tension of the spring 77, and the headrest body 14 inclines to the front while it moves upward.
