PROBLEM TO BE SOLVED: To provide a method of manufacturing vehicle closure parts, and the vehicle closure parts which prevent electrochemical corrosion in a hemming processing portion between different types of metals, and prevent water-insoluble sealer from oozing out. SOLUTION: In a vehicle door 1, the water-insoluble sealer 8 and water-soluble sealer 7 are arranged and applied onto opposed surfaces of an outer panel 2 and an inner panel 3 made of different metal plate materials so that the water-soluble sealer 7 is located closer to an end portion of the outer panel 2 than the water-insoluble sealer 8. After temporarily connecting them to each other, the end portion 2a of the outer panel 2 is folded back to include an end portion of the inner panel 3, followed by hemming processing. Additionally, the water-soluble sealer 7 is expanded toward a folded-back portion 6 folded back in the hemming processing. Then, the water-soluble sealer 7 oozing out from the end portion of the outer panel 2 is removed by water-washing. Thereafter, a coating sealer 9 is applied to the vicinity of the end portion of the outer panel 2 from which the water-soluble sealer 7 is removed by water-washing. COPYRIGHT: (C)2011,JPO&INPIT |
