不斉形状を良好に目隠しすることができる。 FIG. 6 shows a door trim 30 formed through the above-described molding process. That is, in this case, the armrest protruding portion 30 is formed along the shape of the mold surface 11a of the lower mold and the mold surface 13a of the second mold 13.
It is composed of upper and lower epidermis 31 and 32 with a as a boundary. Moreover, the above-mentioned protrusion 14 is provided at the joining edge.
A linear groove 14' corresponding to the area will be formed, but by attaching a decorative band such as a bead to this part in a later process, the asymmetric shape of the bonded part or the inside of the groove will be changed. The asymmetric shape caused by the leaked foam resin can be effectively concealed.
