Abstract

In order to ensure accuracy for positioning two molding members spaced from each other and an outer lens disposed in an opening between the two molding members, a vehicle lighting device includes: a first molding member; a second molding member that is formed separately from the first molding member and is spaced from the first molding member through an opening; and an outer lens, disposed in the opening, having a transmissive surface through which lamp light is transmitted from a depth side toward a front side. The first molding member and the second molding member each have a molding-side positioning portion configured to be positioned relative to the transmissive surface of the outer lens. The outer lens has a first lens-side positioning portion configured to be positioned relative to the first molding member and a second lens-side positioning portion configured to be positioned relative to the second molding member.

First claim

The invention claimed is:

1. A vehicle lighting device comprising:
a first molding member;
a second molding member that is formed separately from the first molding member and is spaced from the first molding member through an opening; and
an outer lens disposed in the opening, the outer lens having a transmissive surface through which lamp light is transmitted from a depth side toward a front side, wherein
the first molding member and the second molding member each have a molding-side positioning portion configured to be positioned relative to the transmissive surface of the outer lens, and
the outer lens has a first lens-side positioning portion configured to be positioned relative to the first molding member and a second lens-side positioning portion configured to be positioned relative to the second molding member.

2. The vehicle lighting device according to claim 1 , wherein
the first molding member and the second molding member each have a plate-shaped molding body portion that is exposed, and a protrusion protruding from an edge portion of the molding body portion on the opening side toward the depth side, and
the molding-side positioning portion is disposed at a front end portion of the protrusion or on a back surface side opposite to a surface of the protrusion on the opening side.

3. The vehicle lighting device according to claim 2 , wherein a surface of the molding body portion and the surface of the protrusion on the opening side are plated.

4. The vehicle lighting device according to claim 1 , wherein
the outer lens has a flange portion protruding from an outer edge of the transmissive surface in a direction away from the opening, and
the first lens-side positioning portion and the second lens-side positioning portion are disposed at the flange portion.

5. The vehicle lighting device according to claim 1 , wherein
the outer lens includes a transparent portion including the transmissive surface, and a non-transparent portion that blocks the lamp light, and
the first lens-side positioning portion and the second lens-side positioning portion are disposed at the non-transparent portion.

6. The vehicle lighting device according to claim 1 , wherein
the molding-side positioning portion of the first molding member and the first lens-side positioning portion of the outer lens are positioned relative to each other by a recess-protrusion interlocking structure, and
the molding-side positioning portion of the second molding member and the second lens-side positioning portion of the outer lens are positioned relative to each other by a recess-protrusion interlocking structure.

7. The vehicle lighting device according to claim 1 , comprising
a lamp housing to which the outer lens and a light source for emitting the lamp light are attached; and
a bracket to which the first molding member, the second molding member, and the lamp housing are attached, the bracket disposed at a vehicle body.
