To enable the molding of a lid part by preventing inevitably occurring peculiar trouble when the bending ridgeline, which is formed by bending the terminal of the main body part constituting a long trim material to the back side of the main body part, has the shape crossing the axial line of the long trim material at a non-right angle.
When the bending scheduled part C' of the terminal of a molding main body 1 supported on the upper surface of a male mold F1 is housed in the lid part molding space V1 formed by the male mold F1 and a female mold F2 while bringing the bending scheduled part C' into contact with the female mold F2 to bend it to the back side of the terminal of the molding main body 1 on the way of the registration both molds F1 and F2, the polymer material of the bending scheduled part C' on the side forming an acute angle (α) along with the bending ridgeline (L0) is allowed to flow toward a side of an obtuse angle (β) to be molded.
