Vehicle lamp
A vehicle lamp 10 includes a lamp body 11 , a sealing material 42 , and a lens member 12 and a leg portion 41 . A groove portion 31 is formed in the lamp body 11 . The sealing material 42 is filled in the groove portion 31 . The leg portion 41 is provided on the lens member 12 . The leg portion 41 is inserted into the groove portion 31 to thereby fix the lamp body 11 and the lens member 12 together via the seal material 42 . A narrow portion 51 is provided at a bottom side of the groove portion 31 and a wide portion 52 is provided at an opening 35 side of the groove portion 31 . A gap of the wide portion 52 is wider than the gap of the narrow portion 51 . The amount of sealing material 42 used in vehicle lamp 10 is limited while ensuring an easy assemblage.
1. A vehicle lamp comprising:
a lamp body in which a groove portion is formed;
a sealing material
a lens member; and
a leg portion provided on the lens member, wherein the leg portion is inserted into the groove portion to thereby fix the lamp body and the lens member together via the sealing material, wherein a narrow portion is provided at a bottom side of the groove portion and a wide portion is provided at an opening side of the groove portion, and wherein a gap between the leg portion and a surface of the wide portion is wider than a gap between the leg portion and a surface of the narrow portion
wherein the narrow portion and the wide portion are connected by an inclined portion that is inclined so as to reduce a width of the groove portion from the wide portion towards the narrow portion,
wherein the sealing material is filled in the gap between the narrow portion and the leg portion, and is also filled in a part of a gap between the wide portion and the leg portion or a part of a gap between the inclined portion and the leg portion.
2. The vehicle lamp according to claim 1 , wherein the sealing material is a moisture-curable adhesive.
3. The vehicle lamp according to claim 2 , wherein a groove depth at the narrow portion is 3 mm or larger, and wherein a gap between the leg portion and the narrow portion is 0.1 mm or larger and 2.0 mm or smaller.
4. The vehicle lamp according to claim 1 , wherein a groove depth at the narrow portion is 3 mm or larger, and wherein a gap between the leg portion and the narrow portion is 0.1 mm or larger and 2.0 mm or smaller.
5. The vehicle lamp according to claim 1 , wherein a side wall of the wide portion extends linearly along a first discrete length of a depth of the groove portion, wherein a side wall of the of the narrow portion extends linearly along a second discrete length of the depth of the groove portion.
6. The vehicle lamp according to claim 5 wherein a side wall of the inclined portion extends angularly along a third discrete length of the depth of the groove portion so as to reduce the width of the groove portion from the wide portion towards the narrow portion.
7. The vehicle lamp according to claim 1 , wherein a first side wall of the narrow portion extends linearly along a first length of a depth of the groove portion, wherein a second side wall of the of the narrow portion extends linearly along a second discrete length of the depth of the groove portion, wherein the first discrete length and the second discrete lengths are different lengths.
8. The vehicle lamp according to claim 7 , wherein the first side wall of the narrow portion and the second side wall of the narrow portion are disposed on opposing sides of the leg portion.
