When the sliding contact with the opening edge is released, it is elastically restored and engaged with the flange portion 15 to attach the shade 23 to the light source 11 (see FIG. 7).

  In a state where the shade 23 is attached to the light source 11, the light source 11 can be removed from the shade 23 by elastically deforming the locking portion 30 b toward the base end portion 30 a and moving the light source 11 backward. Therefore, in a state where the locking portion 30 b is engaged with the flange portion 15, the shade 23 is attached to the light source 11 in a detachable state.

  Next, the shade 23 is fixed to the reflector 7 and at the same time, the connector 16 is detachably coupled to the reflector 7 (see FIG. 8). The fixing of the shade 23 to the reflector 7 and the connection of the connector 16 to the reflector 7 are performed by inserting each part of the shade 23 and the light source 11 into the insertion hole 7a of the reflector 7 from the rear as follows.

  When the shade 23 and the light source 11 are inserted into the insertion hole 7a from the rear, the fixing projections 9 and 9 of the reflector 7 are inserted into the fitting holes 24b and 24b formed in the held portion 24, respectively, and arranged. The mounting walls 10, 10, 10 of the reflector 7 are inserted into the holes 24a.

  When the fixing protrusion 9 is inserted into the fitting hole 24b, the fitting protrusions 27, 27,... Are slidably contacted with the outer peripheral surface of the fixing protrusion 9, as shown in FIG. The pieces 27, 27,... Are spread and the bending rate with respect to the base surface portion 28 is increased.

The forward movement of the shade 23 and the light source 11 relative to the reflector 7 is restricted, and the shade 23 and the light source 11 are positioned with respect to the reflector 7. At this time, the light source 11 is held in a state where the flange portion 15 is in contact with the rear surface of the reflector 7.

  As described above, when the shade 23 is fixed to the reflector 7 and the connector 16 holding the light source 11 is coupled to the reflector 7, a connection plug (not shown) connected to a power supply circuit (not shown) is used for connecting the connector 16. Connected to the protrusion 18. When power is supplied from the power supply circuit to the light source 11 via the connection terminals 14 a, 14 a, and 14 a, light is emitted from the light emitting portion provided in the outer tube 12 of the light source 11, and the emitted light is reflected by the reflector 7. The light is reflected by the surface 7b, transmitted through the cover 3, and irradiated forward.

  In the vehicle headlamp 1 described above, the engagement between the locking portion 30b of the shade 23 and the flange portion 15 of the light source 11 is released, and the elastic deformation portions 21 and 21 of the connector 16 and the mounting wall 10 of the reflector 7 are provided. By releasing the engagement with 10, the light source 11 and the connector 16 can be easily detached from the shade 23 and the reflector 7 (see FIG. 14).

  This is because the front edge of the fitting protrusions 27, 27,... Has a force in a direction to bite into the outer peripheral surface of the fixing protrusion 9, so that the shade 23 remains fixed to the reflector 7. This is because only the light source 11 can be removed in this state.

  In the above example, the fixing protrusions 9 and 9 are provided in the reflector 7 and the fitting hole 24b is formed in the shade 23 to fix the shade 23 to the reflector 7.

Conversely, the attached portion is provided in the light source and the shade is attached to the shade. It is also possible to attach the shade to the light source by forming an attachment hole.

  As described above, in the vehicle headlamp 1, the shade 23 is fixed to the reflector 7 at the same time when each part of the shade 23 and the light source 11 is inserted from the insertion hole 7 a of the reflector 7. At the same time, since the connector 16 that holds the light source 11 is coupled to the reflector 7 and the light source 11 is assembled to the reflector 7, workability in the work of assembling the light source 11 to the reflector 7 can be improved.

  Further, since the shade 23 is fixed to the reflector 7 simultaneously with the assembly of the light source 11, the workability in the assembly operation of the shade 23 to the reflector 7 can be improved in addition to the assembly operation of the light source 11 to the reflector 7. it can.

  In particular, the above-described assembly of each part with respect to the reflector 7 can be performed by inserting each part of the shade 23 and the light source 11 from the insertion hole 7a of the reflector 7, so that it is mechanically performed by a robot or the like regardless of manual work. It is possible to improve the work efficiency.

  Further, since the light source 11 can be removed without removing the shade 23 from the reflector 7, the light source 11 can be easily replaced.

  Furthermore, since the attachment and removal of the connector 16 to and from the reflector 7 are performed by elastically deforming the elastic deformation portions 21 and 21, the attachment and removal of the connector 16 from the reflector 7 can be easily performed.

  In addition, the shade 23 is fixed to the reflector 7 by inserting the fixing protrusions 9 and 9 into the fitting holes 24b and 24b, respectively. Therefore, the shade 23 is used without using a means such as adhesion or welding. Can be firmly and securely fixed to the reflector 7.
