  • Publication number: 20200017154
    Abstract: Manufacturing costs of a resin back door are reduced. After an adhesive is applied to an inner panel, the inner panel and outer panels are placed on top of each other, and relative positions between the outer panel and the inner panel are held by pressing an upper surface portion (first area) of the outer panel in a vehicle body vertical direction by using pressing members (first jigs) and pressing a spoiler (second area) of the outer panel in a vehicle body front-back direction by using pressing members (second jigs). Thereafter, the second jigs are removed from the outer panel, and the inner panel and the outer panel are heated while the upper surface portion of the outer panel is being pressed by the first jigs, thereby curing the adhesive.
