PROBLEM TO BE SOLVED: To prevent the marks of air vent holes from attracting public attention in ordinary use embodiment by a method wherein the positions of the air vent holes are gathered only to the side of a molding. SOLUTION: A front part outside 1 is made into a non-coated specular surface having the center-line mean roughness Ra of 0.1μm or less, the 60 degree specular gloss of 90% or more. A rear part outside 2 is a face, the insertion of a jig or the like in which is set forth as a premise. A the same time, an inner layer is a portion for retaining various mechanical strengths of this molding A. In addition, a plurality of marks 8 of air vent holes are present discontinuously in a side cutting-up line 10 in the side face part 3 of a local curved surface part 9, which connects the front part outside 1 and a side part outside 3, at a position shifting to the front part outside 1 from a parting line 7. As a result, the roll as air venting is fully performed, resulting in developing no hindering of the non-coated specularity of the front part outside 1. |
