PROBLEM TO BE SOLVED: To prevent electrolytic corrosion from occurring when a metallic handle seat cover is attached to a door provided with a metal door surface, thereby to prevent paint peeling and corrosion of the door surface itself due to wetting by water droplets and deterioration of the paint on the door surface to prevent appearance failure around the base portion of the door handle.SOLUTION: A flange portion is molded of an insulating resin, and provided with a base plate, and a flange portion extending outward in a radial direction from an end portion on a rear surface side of an outer peripheral surface of a base plate, the flange portion being possible to effectively suppress occurrence of appearance defect due to electrolytic corrosion, by provision of the door handle seat characterized by being located between the rear face end of the metal handle base cover fitted along the outer peripheral surface of the base plate and a door face.SELECTED DRAWING: Figure 1
【課題】 金属製の扉面を備えた扉に対して金属製のハンドル座カバーを取り付けた際に、電食が発生し、水滴による濡れや扉面への塗装の劣化によって、塗装剥がれや扉面そのものの腐食を進行させ、扉用ハンドルの付け根部分周辺の外観不良を引き起こす原因となっていた。【解決手段】 絶縁性の樹脂によって成形され、基板と、前記基板の外周面の背面側端部から径方向外方に延出してなる鍔部と、を備え、前記鍔部は、前記基板の外周面に沿って嵌着された金属製のハンドル座カバーの背面端と前記扉面との間に位置することを特徴とする扉用ハンドル座の提供によって、電食による外観不良の発生を効果的に抑制することができる。【選択図】 図１
