Abstract: 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.

Abstract: A vehicular lamp in which a weld surface of a weld portion provided on a translucent cover is pressed against a surface to be welded that is formed on a lamp housing, and the translucent cover and the lamp housing are welded by a laser light irradiated from a welding head on the weld portion. The welding head is moved, during the method of making the lamp, along the weld surface, and the angle of the welding head while moving is varied depending on the orientation of the weld surface so that the orientation angle variation amount of the weld surface is set to be equal to or less than 0.5 deg/mm for areas which are adjacent in the moving direction of the welding head.
