Also in this configuration, the lead wire for electrically connecting the lamp holder 3 and the lamp unit 4 is not necessary, and the conductive leaf spring 100 is simply attached to the lamp body 5 for attachment and manufacturing of soldering or molding. No steps are required, and the configuration and manufacturing can be simplified.

Further, as a structure for fitting the lamp unit 4 into the lamp holder 3 and preventing the lamp unit 3 from coming off, a concave hole 37 having an opening dimension smaller than the depth dimension is formed in the lamp holder 3 as shown in FIG. The arrow-shaped fastener 59 may be provided so as to project from the rear surface of the lamp body 5, and the fastener 59 may be press-fitted into the recess 37. Of course, the structure of the lance 36 and the structure of the fastener 59 may be used together.

Alternatively, as shown in FIG. 10, projections 63 are integrally formed on the upper surface and the lower surface of the lens 6 of the lamp unit 4 at a plurality of positions in the length direction. The protrusions 63 are alternately arranged in the length direction of the lens 6 on the upper surface and the lower surface.
As shown in FIG. 1 in an enlarged cross-sectional view taken along the line BB of FIG. 10, the lens 6 is formed into a plate-like shape protruding above and below the lens 6 with a required thickness, and its front side is tapered with a relatively large slope. Face 63
and a tapered surface 63b having a small slope on the back side. In addition, contact portions 514 that are oriented in the vertical direction are formed on the upper side and the lower side of the back surface of the lamp body 5. On the other hand, the lamp holder 3 is provided so as to project its upper and lower edges to the front, and the projection 63 is provided inside the upper and lower edges thereof.
