What is claimed is: 1 . A headrest for a vehicle, comprising: a stay; a headrest body supported by the stay; and a dynamic damper attached to the stay and embedded in the headrest body, wherein the dynamic damper includes: an attachment member having an attachment portion attached to the stay and an opening extending through the attachment member in a front-back direction; an elastic member fixed along its entire perimeter by an edge of the opening and placed in the opening; and a weight embedded in the elastic member and placed in the opening, the attachment member includes a front-side divided body and a back-side divided body placed on a back side of the front-side divided body, and the elastic member is sandwiched between the front-side divided body and the back-side divided body from both sides in the front-back direction, so that the elastic member is fixed along its entire perimeter by the edge. 2 . The headrest according to claim 1 , wherein the front-back direction is a front-rear direction or a left-right direction of the vehicle. 3 . The headrest according to claim 1 , wherein the elastic member includes a front-side elastic body and a back-side elastic body placed on a back side of the front-side elastic body, the weight is sandwiched between the front-side elastic body and the back-side elastic body from both sides in the front-back direction, so that the weight is placed along a boundary plane between the front-side elastic body and the back-side elastic body, and a clearance is defined between the weight and the front-side and back-side elastic bodies along the boundary plane. 4 . The headrest according to claim 3 , wherein the elastic member having the weight embedded therein and the stay are sandwiched between the front-side divided body and the back-side divided body from both sides in the front-back direction, so that the elastic member is fixed along its entire perimeter by the edge and the attachment portion is attached to the stay. 5 . The headrest according to claim 4 , wherein the stay includes a pair of legs extending in an up-down direction and a connecting portion connecting upper ends of the pair of legs, the attachment member is interposed between the pair of legs, and a pair of slit portions opening downward are defined between the attachment member and the pair of legs. 6 . The headrest according to claim 1 , further comprising: a restricting portion that restricts displacement of the weight in the front-back direction. 7 . The headrest according to claim 6 , wherein the restricting portion is a pair of connecting members that are placed on the attachment member on both sides of the opening in the front-back direction so as to extend across the opening. 8 . The headrest according to claim 6 , wherein the restricting portion is a pair of film members that cover the elastic member from both sides in the front-back direction. 9 . The headrest according to claim 6 , wherein the headrest body includes a cushion member made of resin foam, and the restricting portion is a pair of impregnated layers formed by impregnating front and back surfaces of the elastic member with a raw material of the cushion member. 10 . A seat comprising the headrest according to claim 1 .
