Abstract

A vehicle structure includes: an exterior member for a vehicle; and a strippable coating film formed by applying an easily strippable coating material to the exterior member. The coating film includes a design portion formed to cover an outer surface of the exterior member, and a non-design portion continuous with the design portion, the non-design portion being formed to cover at least a side end portion of the exterior member. A film serving as a starting point from which the coating film is stripped off is provided between the exterior member and the non-design portion such that the film is exposed from an edge of the non-design portion.

First claim

What is claimed is:

1. A vehicle structure, comprising:
an exterior member for a vehicle, wherein the exterior member includes:
a first exterior member including a fender panel, and
a second exterior member adjacent to the first exterior member, the second exterior member including a bumper cover;

a strippable coating film on the first exterior member, wherein the strippable coating film includes:
a design portion covering an outer surface of the first exterior member, and
a non-design portion continuous with the design portion, the non-design portion covering at least the outer surface at a side end portion of the first exterior member where the first exterior member and the second exterior member overlap each other; and

an additional film, serving as a starting point from which the strippable coating film is stripped off, wherein the additional film includes:
a lamination part provided between the first exterior member and the non-design portion, and
an exposed part being exposed from an edge of the non-design portion, the exposed part extending from the edge to the second exterior member and being stuck to the second exterior member, wherein

the additional film is transparent,
the strippable coating film includes urethane-based resin or acrylic resin as a main material, and
an adhesive force between the lamination part and the non-design portion is larger than an adhesive force between the strippable coating film and the first exterior member.

2. The vehicle structure according to claim 1 , wherein
the second exterior member is an elastically deformable member.

3. The vehicle structure according to claim 1 , wherein
the additional film has a surface roughness larger than a surface roughness of the first exterior member.

4. The vehicle structure according to claim 1 , further comprising:
a clear layer on an outer side of the strippable coating film.

5. The vehicle structure according to claim 4 , wherein
the additional film has a surface roughness larger than a surface roughness of the first exterior member.

6. A vehicle structure, comprising:
a fender panel;
a bumper cover;
a strippable coating film on the fender panel, wherein the strippable coating film includes:
a first portion covering an outer surface of the fender panel, and
a second portion continuous with the first portion, the second portion covering the outer surface of the fender panel at a portion of the fender panel where the fender panel and the bumper cover overlap each other while being spaced from each other by a gap; and

an additional film, serving as a starting point from which the strippable coating film is to be stripped off, wherein the additional film includes:
a lamination part between the fender panel and the second portion of the strippable coating film, and
an exposed part exposed from an edge of the second portion of the strippable coating film, wherein

the exposed part extends from the edge of the second portion of the strippable coating film, across the gap between the fender panel and the bumper cover, to the bumper cover where the exposed part is stuck to the bumper cover,
the additional film is transparent,
the strippable coating film includes urethane-based resin or acrylic resin as a main material, and
an adhesive force between the lamination part and the second portion of the strippable coating film is larger than an adhesive force between the first portion of the strippable coating film and the fender panel.

7. The vehicle structure according to claim 6 , wherein
the additional film has a surface roughness larger than a surface roughness of the fender panel.

8. The vehicle structure according to claim 6 , further comprising:
a clear layer on an outer side of the strippable coating film.

9. The vehicle structure according to claim 8 , wherein
the additional film has a surface roughness larger than a surface roughness of the fender panel.
