Abstract
A manufacturing method of a seat structure member includes forming a protrusion that protrudes inward on an inside surface of a portion that forms a foaming chamber for a seat pad, on one die and another die that form the foaming chamber. Applying, to a cover, a region that will not be integrated with the seat pad when the seat pad is foam molded, at a location on the cover that corresponds to a location of the protrusion when placing the cover on the inside surface of the foaming chamber. The method further includes arranging the cover following a shape of the protrusion and foam molding the seat pad and forming a space of a recessed portion between the seat pad and the cover, by releasing the one die and the other die after foam molding the seat pad.
