Abstract
A vehicular lighting tool has an emission part, an inner lens located on a rear side of the emission part, and an outer lens located on a rear side of the inner lens, the outer lens has a guide convex portion and a positioning convex portion protruding forward, the inner lens has a guide hole and a positioning hole, the guide convex portion is inserted into the guide hole in a state in which a gap is provided in a leftward/rightward direction, and the inner lens is positioned in the leftward/rightward direction by the positioning convex portion being inserted into the positioning hole.
Claims8
A vehicular lighting tool that is located on a rear end portion of a vehicle and that is configured to emit light to a side behind the vehicle, the vehicular lighting tool comprising:
- an emission part configured to emit light to a rear side;
- an inner lens that is located on a rear side of the emission part and that is extending in a leftward/rightward direction;
- and
- an outer lens that is located on a rear side of the inner lens and that is extending in the leftward/rightward direction,
- wherein the outer lens comprises:
- a guide convex portion and a positioning convex portion that are arranged in the leftward/rightward direction and protruding forward;
- sidewall portions extending forward from end portions of the outer lens in the leftward/rightward direction, respectively;
- and
- inward protruding parts protruding inward in the leftward/rightward direction from end portions of the sidewall portions on the front side,
- wherein the inner lens comprises:
- a fixing part fixed to the outer lens;
- and
- a guide hole and a positioning hole passing through the inner lens in a forward/rearward direction of the vehicle,
- wherein end portions of the inner lens in the leftward/rightward direction face the sidewall portions with a gap therebetween and overlap the inward protruding parts in the forward/rearward direction,
- the guide convex portion is inserted into the guide hole in a state in which gaps are provided in the leftward/rightward direction, and
- the inner lens is positioned in the leftward/rightward direction with respect to the outer lens by the positioning convex portion being inserted into the positioning hole.
A method of manufacturing a vehicular lighting tool that is located on a rear end portion of a vehicle and that is configured to emit light to a side behind the vehicle, the method comprising:
- a lens assembly process of fixing an inner lens, which is extending in a leftward/rightward direction, to an outer lens which is located on a rear side of the inner lens and which is extending in the leftward/rightward direction,
- wherein the outer lens comprises:
- a guide convex portion and a positioning convex portion that are arranged in the leftward/rightward direction and protruding forward;
- sidewall portions extending forward from end portions of the outer lens in the leftward/rightward direction, respectively;
- and
- inward protruding parts protruding inward in the leftward/rightward direction from end portions of the sidewall portions on the front side,
- wherein the inner lens comprises:
- a guide hole and a positioning hole passing through the inner lens in a forward/rearward direction of the vehicle,
- wherein the guide convex portion is located at a first side in the leftward/rightward direction with respect to the positioning convex portion,
- wherein the lens assembly process comprises:
- a first process of making a first end portion, which is located on the first side of the inner lens, to face an inner side surface of the sidewall portion and inserting the guide convex portion into the guide hole in a state in which the first end portion is located on a front side of a second end portion located on a second side which is opposite to the first side,
- a second process of moving the second end portion to a rear side while maintaining a state in which the guide convex portion is inserted into the guide hole, and inserting the positioning convex portion into the positioning hole;
- and
- a third process of fixing the inner lens to the outer lens,
- wherein, in the first process, the guide convex portion is inserted into the guide hole in a state in which a gap is provided in the leftward/rightward direction, and
- in the second process, by inserting the positioning convex portion into the positioning hole, the inner lens is positioned with respect to the outer lens in the leftward/rightward direction.
