Abstract

A method of assembling a vehicle back door includes forming a chamber by joining, with an adhesive, an inner panel made of resin to an outer panel made of resin; and inserting a first holding jig inside the chamber through a hole formed in the outer panel and allowing the adhesive to harden in a state in which a joint portion between the inner panel and the outer panel is sandwiched between and held by the first holding jig and a second holding jig placed outside the chamber.

First claim

What is claimed is:

1 . A method of assembling a vehicle back door, the method comprising:
forming a chamber by joining, with an adhesive, an inner panel made of resin to an outer panel made of resin; and inserting a first holding jig inside the chamber through a hole formed in the outer panel and allowing the adhesive to harden in a state in which a joint portion between the inner panel and the outer panel is sandwiched between and held by the first holding jig and a second holding jig placed outside the chamber.

2 . The method according to claim 1 , wherein:
the hole has a central axis and the joint portion is located on one axial direction side of the hole, and inserting the first holding jig comprises inserting the first holding jig inside the chamber in such a way that the first holding jig extends along the axial direction of the hole.

3 . The method according to claim 1 , further comprising joining a rear window glass to an outside of the outer panel so as to cover the hole with the rear window glass.

4 . The method according to claim 2 , further comprising joining a rear window glass to an outside of the outer panel so as to cover the hole with the rear window glass.

5 . The method according to claim 1 , wherein the inner panel defines an opening over which a vehicle rear window is to be installed.

6 . The method according to claim 5 , wherein the outer panel includes left and right panels that are separately adhered to the inner panel.

7 . The method according to claim 1 , wherein the outer panel includes left and right panels that are separately adhered to the inner panel.

8 . A method of assembling a vehicle back door, the method comprising:
joining, with an adhesive, an inner panel made of resin to an outer panel made of resin so as to form a hollow chamber between the inner and outer panels, the adhesive being applied at a joint portion of the inner and outer panels; and inserting a distal end of a first holding jig through a hole formed in the outer panel until the distal end contacts the joint portion inside the hollow chamber, and allowing the adhesive to harden in a state in which the joint portion is sandwiched between and held by the first holding jig and a second holding jig which contacts the joint portion outside the chamber.

9 . The method according to claim 8 , wherein:
the hole has a central axis and the joint portion is located on a side of the chamber located across the chamber from the hole, and inserting the distal end of the first holding jig comprises inserting the distal end of the first holding jig into the chamber in such a way that the first holding jig extends along an axial direction of the hole.

10 . The method according to claim 8 , further comprising joining a rear window glass to an outside of the outer panel so as to cover the hole with the rear window glass.

11 . The method according to claim 9 , further comprising joining a rear window glass to an outside of the outer panel so as to cover the hole with the rear window glass.

12 . The method according to claim 8 , wherein the inner panel defines an opening over which a vehicle rear window is to be installed.

13 . The method according to claim 12 , wherein the outer panel includes left and right panels that are separately adhered to the inner panel.

14 . The method according to claim 8 , wherein the outer panel includes left and right panels that are separately adhered to the inner panel.

15 . A vehicle back door comprising:
an inner panel made of resin; an outer panel made of resin; and a rear window glass, wherein the inner panel and the outer panel enclose a hollow chamber in a joined state, the rear window glass is joined to a vehicle outside of the outer panel, and at least one hole is formed in the outer panel on a side of the hollow chamber which is opposite to a joint portion between the inner panel and the outer panel, the at least one hole being covered by the rear window glass.

16 . The vehicle back door according to claim 15 , wherein black paint is provided on an inside surface of the rear window glass at a location opposing the at least one hole of the outer panel.
