Abstract

A vehicle light source unit includes an optical supporting portion that supports the optical portion, a metal-made supporting portion, a fixing portion that fixes the metal-made supporting portion and the optical supporting portion in a partial and mutual manner, and a sliding portion that slidably supports the metal-made supporting portion and the optical supporting portion in a partial and mutual manner; the sliding portion is configured in such a way that the metal-made supporting portion and the optical supporting portion can slide on each other in a sliding direction and in such a way as to not only support the optical supporting portion against the metal-made supporting portion but also support the metal-made supporting portion against the optical supporting portion, toward the both sides of a supporting direction that are perpendicular to the sliding direction.

First claim

The invention claimed is:

1. A vehicle light source unit comprising:
a light-emitting portion;
a heat radiation portion that is fixed to the light-emitting portion;
an optical portion that guides light from the light-emitting portion;
an optical supporting portion that supports the optical portion;
a metal-made supporting portion;
a fixing portion that fixes the metal-made supporting portion and the optical supporting portion in a partial and mutual manner; and
a sliding portion that slidably supports the metal-made supporting portion and the optical supporting portion in a partial and mutual manner,
wherein the sliding portion is configured in such a way that the metal-made supporting portion and the optical supporting portion can slide on each other in a predetermined sliding direction and in such a way as to not only support the optical supporting portion against the metal-made supporting portion but also support the metal-made supporting portion against the optical supporting portion, toward one and the other sides of a predetermined supporting direction that is perpendicular to the sliding direction.

2. The vehicle light source unit according to claim 1 , wherein the optical supporting portion is made of resin.

3. The vehicle light source unit according to claim 1 , wherein the sliding portion is disposed at an end portion of the optical supporting portion.

4. The vehicle light source unit according to claim 1 ,
wherein one the fixing portion is provided, and
wherein a plurality of the sliding portions are provided.

5. The vehicle light source unit according to claim 1 , wherein the sliding direction is substantially parallel to the longitudinal direction of the optical supporting portion.

6. The vehicle light source unit according to claim 1 , wherein the metal-made supporting portion is coupled with a base portion by an angle-variable coupling portion that can adjust a mounting angle of the metal-made supporting portion with respect to the base portion.

7. The vehicle light source unit according to claim 1 , wherein the sliding direction is substantially perpendicular to the optical axis direction of the optical portion.

8. The vehicle light source unit according to claim 1 , wherein the supporting direction is substantially parallel to the optical axis direction of the optical portion.

9. The vehicle light source unit according to claim 1 , wherein the sliding portion has a gap in the direction intersecting the sliding direction and is slidable by a distance corresponding to the gap in the direction along which the gap is provided.

10. The vehicle light source unit according to claim 1 ,
wherein one the fixing portion is provided,
wherein a plurality of the sliding portions are provided and arranged radially around the fixing portion, and
wherein the respective sliding directions of the sliding portions are substantially parallel to the radial direction around the fixing portion.

11. The vehicle light source unit according to claim 1 , wherein the light-emitting portion is fixed to the metal-made supporting portion without the intermediary of the optical supporting portion.

12. The vehicle light source unit according to claim 1 ,
wherein the sliding portion has a sliding groove portion that is groove-shaped and provided at any one of the metal-made supporting portion and the optical supporting portion and a sliding protrusion portion that is protrusion-shaped, provided at the other one of the metal-made supporting portion and the optical supporting portion, and slidably inserted into the sliding groove portion, and
wherein the sliding direction is the extending direction of the sliding groove portion and the supporting direction is the transverse direction of the sliding groove portion.

13. The vehicle light source unit according to claim 1 , wherein at the metal-made supporting portion, the sliding portion has a sliding surface that extends in the sliding direction and faces toward one side in the supporting direction and a sliding surface that faces toward the other side in the supporting direction, and at the optical supporting portion, the sliding portion has two sliding surfaces that face the respective sliding surfaces of a member at the metal-made supporting portion.

14. The vehicle light source unit according to claim 1 ,
wherein the sliding portion has a columnar portion that is columnar and provided at any one of the metal-made supporting portion and the optical supporting portion and a tubular portion that is tubular, provided at the other one of the metal-made supporting portion and the optical supporting portion, and slidably fits with the columnar portion, and
wherein the sliding direction is the axle direction of the columnar portion and the supporting direction is the radial direction of the columnar portion.

15. The vehicle light source unit according to claim 1 ,
wherein the sliding portion has a headed screw that is fixed to any one of the metal-made supporting portion and the optical supporting portion and a transversely long through-hole portion that is provided in the other one thereof and whose through-hole through which the headed screw passes is elongated in the transverse direction perpendicular to the penetration direction of the headed screw, and
wherein the sliding direction is the transverse direction and the supporting direction is the penetration direction.

16. The vehicle light source unit according to claim 1 , wherein the metal-made supporting portion is supported through the intermediary of an elastic member.

17. The vehicle light source unit according to claim 1 , wherein the sliding part, at the optical supporting portion, of the sliding portion is made of metal.

18. The vehicle light source unit according to claim 1 , wherein the sliding part, at the optical supporting portion, in the sliding portion is a part of a metal portion inserted into and molded with the optical supporting portion made of resin.

19. The vehicle light source unit according to claim 1 , wherein the optical portion has a long shape in the horizontal direction, and
wherein the sliding direction is substantially parallel to the horizontal direction.
