Patent ID: 10843251

Abstract:
In a method for joining members of the present invention, a B-pillar, a rocker, a side panel served as frame members of a vehicle body, and an elastic body are provided. The B-pillar includes a tubular portion and an extension portion extended from the tubular portion. The rocker includes a first hole portion. The side panel includes a support portion. Next, the tubular portion of the B-pillar is inserted into the first hole portion of the rocker. The elastic body is inserted into the tubular portion of the rocker. The elastic body is pressurized in an axial line L1 direction of the tubular portion of the B-pillar to be expanded outward in a radial direction of the axial line L1, so that the tubular portion of the B-pillar is expanded and deformed to be joined to the first hole portion of the rocker by press-fitting. Further, the extension portion of the B-pillar and the support portion of the side panel are joined by a method different from joining by press-fitting.
