Definitions

- the in-vehicle light source unit described in Patent Document 1 below is known.
- the light emitting diode and the projection lens as the light emitting unit and the optical unit are supported by a metal light source support block, and a plurality of light source support blocks are supported by a common metal support member. It is configured. Therefore, in the technique of Patent Document 1, the heat generated by each light emitting diode is transmitted to the metal support member through the metal light source support block with good thermal conductivity, and the temperature rise of the light emitting diode is suppressed. It is configured as follows.
- the lower end surface of the light source support block is configured to be fixed to a metal support member in order to improve thermal conductivity (paragraph 0043 of Patent Document 1). . Therefore, in the technique of Patent Document 1, when one or both of the light source support block and the metal support member are deformed due to an external force or temperature change, one deformation is transmitted to the other, and the other is deformed such as warping. The deformation is restrained by the other and stress is generated, and there is a possibility that deformation such as warpage occurs in one. When deformation such as warpage occurs, the optical axis of the optical unit may be shaken. In particular, when one or both of the light source support block and the metal support member are reduced in weight, the light source support block and the metal support member are easily deformed, and the optical axis of the optical unit is likely to be shaken.

- the in-vehicle light source unit includes a light emitting unit, an optical unit that guides light from the light emitting unit, an optical support unit that supports the optical unit, a metal support unit, the metal support unit, and the optical unit.
- a fixing portion that partially fixes the support portion to each other; and a sliding portion that supports the metal support portion and the optical support portion so as to be partially slidable with respect to each other.
- the metal support portion and the optical support portion are slidable with each other in a predetermined sliding direction, and are provided on both sides of one side and the other side of the predetermined support direction orthogonal to the sliding direction.
- the optical support unit is supported with respect to the metal support unit, and the metal support unit is supported with respect to the optical support unit.
- the sliding portion slides in a predetermined sliding direction, It is possible to escape the deformation in the sliding direction. Therefore, it is possible to suppress the generation of stress due to the restraint of deformation and deformation such as warpage, and it is possible to suppress deformation of the other due to deformation in one sliding direction.
- the metal support portion and the optical support portion are configured to mutually support the metal support portion and the optical support portion on both sides of the support direction orthogonal to the slide direction. It is possible to suppress deformation such as warpage in the support direction in the optical part and the optical support part. Therefore, even if one or both of the metal support portion and the optical support portion are deformed due to an external force or a temperature change, it is possible to suppress the occurrence of shake of the optical axis of the optical portion.
