Description of the Related Art Japanese Unexamined Patent Publication No. 59-11012 discloses a method in which a layer made of an elastomer or semi-rigid urethane is completed at a predetermined portion of the surface of a seat cushion and then a stock solution of a soft foam of a main part is foamed. JP-A-62-18
No. 4816 has a method for manufacturing a different-hardness seat cushion body in which a soft sheet is installed on the side wall portion on the peripheral edge side of the seat cushion body and a urethane foam having a high hardness is applied to the surface thereof to prevent the urethane from spilling. Also, JP-A-61-2
There is one in which a high hardness urethane is prevented from entering a low hardness main portion by using a shielding plate of No. 83512.

などの問題点があった。In spray (spraying) foaming, a high-pressure foaming machine is not particularly used because the polyurethane foaming stock solution is scattered when urethane is applied. In addition, since a high-pressure foaming machine discharges a large amount, a large amount is scattered. When applying the polyurethane foaming undiluted solution with a spraying device, injecting it with the nozzle of the stirrer causes a lot of scattering, and the high hardness urethane scatters and adheres to the soft (flexible) layer of the low hardness part, making it feel lumpy. There are problems such as poor riding comfort. It is difficult to prevent urethane from scattering with the current mixing head (stirring equipment) of the foaming machine. There was a problem that the low-pressure type stirring equipment did not scatter, but it did not turn around easily and could not spray vertical surfaces.
