PROBLEM TO BE SOLVED: To obtain a resin outer plate member for vehicle and a vehicle back door by which a dimensional difference between a resin member and a fiber-reinforced resin member which is generated by thermal expansion can be absorbed in the case where the members are joined.SOLUTION: A protrusion 44 is provided in a door outer panel 24. Thus, the protrusion 44 is compressed along a surface direction of the door outer panel 24 when the door outer panel 24 is thermally expanded, a gap 50 in the protrusion 44 is designed to be crushed. Specifically, compressive deformation of the protrusion 44 absorbs a dimensional difference generated between the door outer panel 24 and a door inner panel 22 along the surface direction of the door outer panel is absorbed. In short, according to this embodiment, in the case where the door outer panel 24 formed of a resin member and the door inner panel 22 formed of a fiber-reinforced resin member are joined to each other, a dimensional difference between the door outer panel 24 and the door inner panel 22 generated by thermal expansion can be absorbed. |
