According to this method, the number of interior materials can be reduced by reducing the wall thickness of the hollow core material. In addition, since air pressure is applied from inside the hollow core material against the foaming pressure from the outside of the foamed synthetic resin, there is no possibility of the hollow core material being pushed (~ crushed or deformed). There is no risk of this, and when applied to a headrest, air can be press-fitted using the headrest stay, reducing the impact force on the rear seat occupant in the event of a collision with the rear seat occupant. It is possible to obtain a method for manufacturing a vehicle interior material having a hollow core material, which is excellent in safety and has a hollow core material.
