PURPOSE: To be able to mold the molding of a structure having a gradual change part gradually varying at either the depth of a groove or the thickness of a swelled part or both via a mounting site by allowing a protruding piece to protrude from the side of the swelled part for forming a decorative part to provide the groove opened at the side at the rear side of the piece. CONSTITUTION: An extrusion opening 15 capable of extruding a side edge molding of the maximum sectional part of a molding is provided at a stationary molding die 14, and the shape itself of the opening 15 is altered by using two types of first and second moving molding dies 16, 17 movable along the direction perpendicular to the extruding direction of the molding, thereby varying the depth of the groove formed at the rear side of a groove lip or the thickness of the swelled part for forming a decorative part or the both. |
