A seat pad with improved thermal comfort and improved vibration absorptivity and a seat pad manufacturing method for easily obtaining the seat pad are provided. In the seat pad (), when a surface portion () up to 10 mm from a surface () is cut out and the air permeability ARof the surface portion () is measured in compliance with JIS K 6400, the air permeability ARis more than 5 cc/cm/sec and 25 cc/cm/sec or less. The seat pad manufacturing method is a seat pad manufacturing method for obtaining the seat pad () by supplying a molding material into a molding die and performing foam molding. As the molding die, a molding die an inner surface of which is covered with polystyrene or polyethylene is used.

To provide a component-temporarily holding member and a component mounting jig that do not require removal of a component installation jig after a foamed resin molding is demolded. In a component-temporarily holding memberhaving a temporary holding partfor temporarily holding a componenthaving a locking partlockable to another member when mounting the componentby locking the locking partin a component mounting positionof a forming diefor a foamed resin molding, the holding force of the temporary holding partis less than the force with which the locking partis locked in the component mounting position

The present invention is an apparatus for manufacturing a foam molded product in which a foam molded product (A,B) is formed by integrally adhering together a foam body () that is formed by the foaming of a foaming raw material, and an air-permeable component (). A cavity () is provided between a plurality of mold components () and is defined by respective cavity surfaces () of the mold components ().

Method of manufacturing foam molded product, apparatus for manufacturing foam molded product, and foam molded product

The present invention is a method of manufacturing a foam molded product in which a foam molded product (A,B) is formed by integrally adhering together a foam body () that is formed by the foaming of a foaming raw material, and an air-permeable component () using an apparatus for manufacturing a foam molded product (A,B) that is provided with a cavity () between a plurality of mold components () that is defined by respective cavity surfaces () of the mold components ().

A mold for foam molding which can sufficiently prevent burrs from being formed on a molded product, and a foam molding method using the mold are provided. A grooveinto which a packing seal is to be fitted is formed in a mating surfaceof a lower moldso as to extend around a cavity. The groovehas a deep groove portionwhich is deeply recessed from the mating surface, and a shallow groove portionwhich is located on the cavityside with respect to the deep groove portionand which continues to the deep groove portion. A portion of the mating surfacethat extends from its edge on the cavityside down to the groove 6 has a width 'a' of from 0.1 mm to 10 mm. A packing sealhas a base portionwhich is inserted into the deep groove portion, and an overhang portionwhich continues to the base portionand is engaged with the shallow groove portion
