  If the light source unit 2 of the present embodiment is configured as described above, when the seal member 9 is inserted into the boss 514, the air inside the boss 514 can escape to the outside of the boss 514 through the vent hole 900. it can. In addition, it is preferable that the inner diameter of the air hole 900 is set to a size (for example, about 0.5 mm) that does not allow rainwater to enter the air hole 900 due to the surface tension of water.

  Further, as shown in FIG. 14B, the seal member 9 is preferably provided with check valves 901 at both ends of the vent hole 900 so that the vent hole 900 can be opened and closed. When the sealing member 9 is inserted into the boss 514, these check valves 901 can release air inside the boss 514 from the vent hole 900 by opening toward the outside of the boss 514. On the other hand, after the seal member 9 is inserted into the boss 514, the check valve 901 does not open toward the inside of the boss 514 even under atmospheric pressure. The possibility of intrusion can be reduced.

  By the way, in the light source unit 2 of this embodiment, the connecting member 82 of the fixture 8 prevents the seal member 9 from coming out from the opening of the boss 514. However, as shown in FIG. 15A, a plate member 515 is attached to the bottom wall 510 of the end member 51, and the plate member 515 may prevent the seal member 9 from coming out of the opening of the boss 514. The plate member 515 is preferably formed of a synthetic resin material into a rectangular flat plate shape. On the other hand, a plurality of protrusions 516 are preferably provided around the opening of the boss 514 in the bottom wall 510. And the front-end | tip part of the processus | protrusion 516 is penetrated by the some through-hole 5150 provided in the board | plate material 515, respectively. The tip portion of each protrusion 516 is formed wider than the inner diameter of the through hole 5150. Therefore, when the tip portion of each protrusion 5156 passes through the through hole 5150, the plate material 515 is prevented from coming off by each protrusion 5156.

  Alternatively, as illustrated in FIG. 15B, a protrusion 5100 that protrudes inward may be provided on the periphery of the opening of the boss 514 in the bottom wall 510. The protrusion 5100 is preferably formed in an annular shape having an inner diameter slightly smaller than the outer diameter of the main body 90 of the seal member 9. Therefore, the main body 90 of the seal member 9 inserted into the boss 514 is prevented from coming off by the protrusion 5100. In addition, it is preferable that the protrusion 5100 is configured to gradually narrow the inner diameter from the outside to the inside of the boss 514.
