A cover has a breathable first portion arranged on a seating side of a seat structure member, a second portion that is laminated to the first portion and inhibits penetration of resin foam material, and a passage portion through which air passes that is provided on the second portion. A protruding portion is arranged face-to-face with the passage portion while the cover is arranged in a cavity, and the cushion is formed with an interposed member that is less rigid than the cover being interposed between the passage portion and the protruding portion. |
