A light source portion 31 in which a substrate penetrating portion 314 is formed connecting a region in which the element 310 is not mounted and a non-mounting surface 313 which is the other surface on the opposite side of the mounting surface 312, and a pedestal main portion 320 in which the light source portion 31 is arranged are provided. In addition, the pedestal main portion 320 has a region corresponding to the substrate penetrating portion 314 on the first surface 321 facing the non-mounting surface 313 of the pedestal main portion 320 and a second surface 322 opposite to the first surface 321. A pedestal 32 having a holding portion passage hole which is a connecting pedestal penetrating portion and a spring receiver 36 as a substrate holder arranged on the second surface 322 are provided, and the spring receiver 36 is provided on the second surface 322. The engaging portion 363 that engages with the pedestal main portion 320 by sliding along the pedestal, and the substrate penetrating portion as it slides while being inserted into the holding portion passing hole and the substrate penetrating portion 314 from the side of the second surface 322. It has a substrate holding portion 370 that moves 314 and overlaps a region other than the substrate penetrating portion 314 of the substrate 311 in a direction intersecting the second surface 322 in a state where the engaging portion 363 is engaged to the pedestal main portion 320. Therefore, it functions as a board holder. Therefore, even when the substrate 311 is separated from the pedestal 32, the substrate 311 is held by the substrate holding portion 370 of the spring receiver 36, so that the substrate 311 does not fall off toward the cover 70.

Further, the spring receiver 36 slides along the second surface 322 to engage with the pedestal main portion 320, and the holding portion passing hole and the substrate penetrating portion 314 from the side of the second surface 322. As the substrate 311 slides along the second surface 322 in the state of being inserted into and, the relative position with the substrate penetrating portion 314 changes, and the substrate 311 is in a state where the engaging portion 363 is attached to the pedestal main portion 320. Since it has a substrate holding portion 370 that overlaps a region other than the substrate penetrating portion 314 in the above and the direction intersecting the second surface 322, it functions as a substrate holder. Therefore, even when the substrate 311 is separated from the pedestal 32, the substrate 311 is held by the substrate holding portion 370 of the spring receiver 36, so that the substrate 311 does not fall off toward the cover 70.

The substrate penetrating portion 314 is formed so as to follow the sliding direction of the spring receiver 36 that functions as the substrate holder. Therefore, the sliding of the spring receiver 36 and the movement of the substrate holding portion 370 included in the spring receiver 36 are not hindered, and the spring receiver 36 slides smoothly along the second surface 322, and the spring receiver 36 slides smoothly. The 36 can be engaged with the pedestal main portion 320 without burden.

Further, the substrate penetrating portion 314 is formed corresponding to the sliding distance (length) of the spring receiver 36 that functions as the substrate holder. Therefore, with the spring receiver 36 engaged to the pedestal main portion 320, the substrate holding portion 370 of the spring receiver 36 intersects the second surface 322 with a region other than the substrate penetration portion 314 of the substrate 311. Even when the substrate 311 is separated from the pedestal 32, the substrate 311 is held by the substrate holding portion 370 of the spring receiver 36, so that the substrate 311 does not fall off toward the cover 70.

The substrate penetrating portion 314 is formed so as to follow the sliding direction of the substrate 311. Therefore, in a state where the spring receiver 36 functioning as the substrate holder is engaged with the pedestal main portion 320, the direction in which the substrate holder 370 intersects the region other than the substrate penetration portion 314 of the substrate 311 and the second surface 322. The substrate 311 can be slid so as to overlap with. That is, since the substrate 311 can be installed on the pedestal 32 after the spring receiver 36 that functions as the substrate holder is attached to the pedestal main portion 320, the light source unit 30 is not restricted by the assembly procedure.

Further, the substrate penetrating portion 314 is formed corresponding to the distance (length) in which the substrate 311 slides. Therefore, after the spring receiver 36 that functions as the substrate holder is engaged with the pedestal main portion 320, the substrate 311 is slid, and in a state where this sliding is completed, the substrate holder 370 that the spring receiver 36 has is , The substrate 311 overlaps the region other than the substrate penetrating portion 314 in the direction intersecting the second surface 322, and the substrate 311 has the substrate that the spring receiver 36 has even when it is separated from the pedestal 32 in the state where the sliding is completed. Since it is held by the holding portion 370, it does not fall off toward the cover 70.

The substrate penetrating portion 314 is formed corresponding to the shape of the substrate holding portion 370 in the direction in which the substrate holding portion 370 is inserted. Therefore, the substrate holding portion 370 is not hindered from being inserted into the substrate holding portion insertion hole 3232, and the substrate holding portion 370 can be smoothly inserted into the substrate holding portion insertion hole 3232.

Further, in the spring receiver 36 that functions as a substrate holder, the engagement portion 362 and the substrate holder 370 are integrally formed. Therefore, it is not necessary to separately provide the spring receiver 36 attached to the pedestal and the substrate holder, and the light source unit has a simple structure, so that the material cost can be reduced. Further, since only the spring receiver 36 that functions as the substrate holder is attached to the pedestal, the manufacturing cost can be reduced.
