PROBLEM TO BE SOLVED: To provide a comfortable feeling of coolness by arranging a regenerating agent pack, in which regenerating agents are stored, between the surface of the heat-contact side of a pad and a skin in a removable manner. SOLUTION: A regenerating agent pack 20 is formed by filling regenerating agents 21 in a bag 22 substantially at no space and melting and closing the opening of the bag. The frozen regenerating agent pack 20 is arranged in a regenerating agent pack placement area 16 on a pad 11 via the opening 17 of a headrest and a cover 18 is closed. In this way, the headrest grants a comfortable cool feeling to an occupant whose head is fitted thereto. The cool feeling lasts long until the regenerating agents 21 in the regenerating agent pack 20 are set back to be completely gelled. Since a skin 13 is provided with an opening 17 to allow the open/close of the regenerating agent pack placement area 16, the regenerating agent pack 20 in which the regenerating agents are gelled at a room temperature can be easily removed for replacement. |
