According to this configuration, even if the translucent cover 42, which is long in one direction, expands and contracts in the axial direction, the upper and lower water blocking members 70U and 70S do not protrude to the outside from the translucent cover 42, so that the water blocking is more reliable. Can be secured. Since the gap 73 is formed at the lower end of the lighting device L, the dew condensation generated inside the case 40 can be drained from the gap 73 at the lower end of the lighting device L.

The lighting device L is provided with an axial positioning portion for determining the vertical position of the light source unit 30 on the tip surface 67 of the lower insertion portion 66. According to this configuration, since the light source unit 30 is arranged above the lower insertion portion 66 in the vertical direction of the case 40, even if water enters the inside of the case 40 through the opening at the lower end portion of the case 40. , It is possible to make it difficult to reach the light source unit 30.

The case 40 of the lighting device L has a translucent cover 42 on the front side. The front end surface 67 of the lower insertion portion 66 is provided with a back surface 68R of a protruding portion 68 that determines the position of the light source unit 30 in the front and back directions. According to this configuration, the position of the light source unit 30 in the front and back directions is determined by the back surface 68R of the protrusion 68, so that the distance between the light source unit 30 and the translucent cover 42 can be kept constant.
