The vehicle seat according to claim 1 , wherein the dynamic damper is attached to the panel members in a state where tension is applied to the leg part. 3. The vehicle seat according to claim 1 , wherein: the panel members are press-formed products of a metallic sheet; and the panel members are joined to each other by welding or squeezing. 4. The vehicle seat according to claim 3 , wherein: the panel members are constituted by press-formed products that are folded up at an integral hinge and joined to each other; and the integral hinge is formed by connecting side parts of the press-formed products with each other. 5. A headrest for a vehicle seat, comprising: a stay forming a skeleton of the headrest; a pair of panel members that sandwich a part of the stay from front and rear or above and below and are joined to each other through outer peripheries so as to form a space inside; a cushion material formed so as to cover the panel members and the part of the stay; and a dynamic damper arranged inside the space, wherein: the dynamic damper includes a weight, and an elastic body that elastically supports the weight, the elastic body including a leg part extending in a direction away from the weight; and a part of the leg part is attached to the pair of panel members by being sandwiched by the pair of panel members. 6. The headrest according to claim 5 , wherein the dynamic damper is attached to the panel members in a state where tension is applied to the leg part. 7. The headrest according to claim 5 , wherein: the panel members are press-formed products of a metallic sheet; and the panel members are joined to each other by welding or squeezing. 8.
