Claims

[Scope of utility model registration claim] In addition to dividing the engine room and the passenger compartment,
The panel on the passenger compartment side of the darts panel is molded to match the shape of the panel surface on the passenger compartment side of the darts panel, and has a through hole through which a connecting part for connecting equipment on the engine room side and equipment on the passenger compartment side passes through. A darts panel insulator that is attached to a surface is made of a thin vinyl chloride plate and a urethane foam layered on one side of the thin vinyl chloride plate. A female mold which is preformed and has a recess having a diameter larger than the hole diameter at a position corresponding to the position of the hole in the thin vinyl chloride sheet, and the above of the datshi panel that protrudes into the inside of the hole in the thin vinyl chloride sheet. The vinyl chloride thin plate is placed between a male mold having a protrusion having a diameter smaller than the through hole, and urethane resin is injected between the vinyl chloride thin plate and the male mold to cause foaming. A sealing portion is formed on the thin vinyl chloride plate, extending from one side of the sheet through the inner peripheral surface of the hole to the other side, and the sealing portion is brought into close contact with the connecting part by its own elasticity. Datsushi panel insulator.
