いる。2. Description of the Related Art In general, a rear parcel for a vehicle has a surface material 1 such as a non-woven fabric or a woven fabric coated on a surface of a base material 2 made of a mixture of wood powder and synthetic resin as shown in FIGS. In order to increase the strength of the base material 2, the metal plate material 3 is attached to the back surface of the base material 2 to reinforce the base material 2 with the metal plate material 3.

れている。However, since this is extremely time-consuming, the skin material 1 and the base material 2
It is also practiced to insert-mold the metal plate material 3 when integrally molding with a molding die. In the insert molding, the through holes 4 are provided in the metal plate material 3 as shown in FIG. 7, and the molding material of the base material 2 is press-fitted into the through hole 4 to fix several parts of the metal plate material 3 by the bosses 5. It is supposed to be fixed.
