PROBLEM TO BE SOLVED: To increase the rigidity of a partition wall, which divides a light chamber, in a longitudinal direction of a section through the wall. SOLUTION: A horizontal part 151, 331, 153, and 333 which increase the rigidity of a partition wall 32 in a vertical direction, which is an elongated portion in a nearly perpendicular direction (horizontal direction) to a longitudinal direction (vertical direction) of a section through the partition wall 32, are provided in a partition seal recessed part 15 of a lamp housing 1 and a partition seal projecting part 33 of an inner panel 3. As a result, the horizontal part 151, 331, 153, and 333, which increase the rigidity of the partition wall 32 in a vertical direction, eliminate the danger of the partition wall 32 becoming rickety due to a vibration in a vertical direction. |
