PURPOSE:To eliminate troubles such as an ripple phenomenon and falling-off, etc., of a decorative molding by allowing a buffer material to be interposed between grooves for mounting the molding and a resin mold. CONSTITUTION:In a state where a decorative molding 11 is mounted on an arm rest 10, right and left mounting backlashes are eliminated by a buffer material 14, and any extrusion due to deviation, etc., of the molding 11 is previously prevented. And, although the arm rest 10 is subjected to thermal expansion or contraction along its lengthwise direction, the width of a mounting hole 13 is wider than that of a tongue piece part 12a of a mounting clip 12 in a mounting groove 10a on the surface side, so that a joining part therebetween is slided in responce to its thermal expansion or contraction. Further, on both sides of the arm rest 10, the buffer material 14 is interposed into a gap part therebetween. Accordingly, the difference of thermal expansion or contraction between the arm rest 10 and the decorative molding 11 are absorbed in this elastic deformation. |
