Interior parts such as the trunk side finisher and trunk rear finisher are installed to improve the appearance and design. Recently, there has been a tendency to reduce the weight and cost of parts. Even for this kind of interior parts, instead of the laminated structure, a single fibrous base material made of non-woven fabric or felt is cold. There is a tendency that a single structure that is compressed by a means such as a press or a hot press to form a component having a required shape is often used.

ようにしたものである。Means for Solving the Problems The present invention which achieves the above-mentioned object, comprises a method for producing an automobile interior part, which comprises compression-molding a fibrous base material such as a non-woven fabric or felt impregnated with a binder resin. The mold surface located on the product surface side is smooth
Surface and the convex surface is provided on the mold surface located on the back side of the product.
Using a press die, the outer peripheral edge portion to be subjected to trim cut processing during the compression molding is compressed more than the general portion to form a thin and flat cross-sectional shape, and the density of the general portion is reduced by this compression. 0.13 to 0.18 g / cm 3, and the density of the outer peripheral edge portion is increased to 0.36 to 0.90 g / cm 3 to impart rigidity at the time of cutting to the outer peripheral edge portion, and thereafter the outer peripheral edge portion. The part is cut to form a part having a required shape.
