Resin molded member of vehicle lamp and vehicle lamp
A resin molded member for a vehicle lamp includes a first resin molded part, a second resin molded part, a bent resin molded part bent and molded to have a groove section between the first resin molded part and the second resin molded part, and a rib wall that is disposed inside the groove section and that is configured to connect between a first inclined wall and a second inclined wall which form the groove section of the bent resin molded part, wherein the rib wall is formed at a position overlapping with a gate mark which is formed on at least one of the first inclined wall and the second inclined wall through injection molding.
1. A resin molded member for a vehicle lamp obtained through injection molding, the resin molded member comprising:
a first resin molded part;
a second resin molded part;
a bent resin molded part bent and molded to have a groove section between the first resin molded part and the second resin molded part; and
a rib wall that is disposed inside the groove section and that is configured to connect between a first inclined wall and a second inclined wall which form the groove section of the bent resin molded part,
wherein the rib wall is formed at a position overlapping with a gate mark, and the gate mark is formed through injection molding on a surface opposite to a surface of either the first inclined wall or the second inclined wall that forms the groove section.
2. The resin molded member for a vehicle lamp according to claim 1 , wherein the rib wall is formed to protrude from a bottom surface of the groove section more than a position overlapping with the gate mark.
3. The resin molded member for a vehicle lamp according to claim 1 , wherein the rib wall is formed to protrude from a bottom surface of the groove section more than a folded section formed between the first inclined wall and the second inclined wall.
4. The resin molded member for a vehicle lamp according to claim 1 , wherein the bent resin molded part has a shape in which an opening angle at a position where the first inclined wall and the second inclined wall are connected to the rib wall is at least an acute angle.
5. The resin molded member for a vehicle lamp according to claim 1 , wherein the groove section is formed to extend in a direction crossing the rib wall.
6. The resin molded member for a vehicle lamp according to claim 1 , wherein the rib wall and gate mark are located in a plane such that resin travels from a gate along a linear path to the first resin molded part and second resin molded part during injection molding.
7. A vehicle lamp comprising the resin molded member according to claim 1 .
