  In addition, although the thing light-molded in the block shape separately from the holder 3 was illustrated as the light guide 13, the optical fiber can also be used.
  Further, the structure in which the light emitting unit 10L is configured by the light emitting surface 13a of the light guide 13 is illustrated, but the light source 11 is directly disposed in the gap 4 without using the light guide 13 in the optical system. 11 itself may be the light emitting unit 10L.
  In the structure of the first embodiment, as shown in FIG. 3, the holder 3 has a recess 5 for housing and arranging the lamp unit 10, and therefore the mirror body 2 is not bonded to a portion corresponding to the recess 5. An area arises.
  Therefore, in the second embodiment shown in FIG. 4, the opening of the recess 5 is closed with a lid 9, and the lid 9 and a general part of the holder 3 (a flat part not provided with the recess 5). The mirror body 2 is bonded and fixed.
  In the present embodiment, the lid 9 is integrally formed with a block-shaped light guide 13 formed separately from the holder 3.
  Therefore, according to the configuration of the second embodiment, a decrease in the bonding area between the mirror body 2 and the holder 3 due to the presence of the concave portion 5 of the holder 3 can be compensated by the lid 9. Adhesion quality can be improved.
  Further, by integrally forming the lid 9 on the light guide 13, the opening of the recess 5 can be closed by the lid 9 simultaneously with the assembly of the light guide 13 to the recess 5. There is no bulk.
  The arrangement of the lid 9 is not limited to this embodiment, and it is of course possible to form the lid 9 separately from the light guide 13 and close the opening of the recess 5.
  For example, as described above, when the block-shaped light guide 13 is integrally formed with the holder 3 by two-color molding, or when an optical fiber is used as the light guide 13, the lid 9 is formed as a separate body and the recess is formed as a recess. 5 is provided to cover the opening.
  In this case, the lid 9 is fixed to the peripheral edge of the opening of the concave portion 5, which is a welding means such as vibration welding, ultrasonic welding, laser welding, hot plate welding, or adhesive, hot melt, double-sided adhesive tape. Adhering means such as, or a fixing means using a rubber seal ring can be selectively employed.
