Abstract

PROBLEM TO BE SOLVED: To prevent the generation of wind noise and to improve water discharging performance without increasing a cost for manufacturing a metallic mould. SOLUTION: A drain hole 15 is provided in a part 10 close to a vehicle rear side of the parting line PL of a mirror housing 1 in the parting direction of a first metallic mould 41. Thus, since the necessity of a third metallic mould for forming the drain hole 15 is eliminated only by forming a projecting part 40 for forming the drain hole 15 in the first metallic mould 41, a cost for manufacturing a metallic molud for forming the mirror housing 1 is not increased. Also, since no vertical surfaces opposite the advancing direction of a vehicle are formed in the drain hole 15, the incursion of wind through the drain hole 15 into the mirror housing 1 is prevented during vehicle running. Thus, the generation of a wind cutting sound is prevented, and water discharging performance is improved.
