Therefore, the conductors arranged on the wiring portion and the fixed pedestal portion at the time of wiring the conductors are welded outside the wiring portion, so that the resin in the socket mounting opening and the contact portion with the socket is not sealed. Inflow and the like are eliminated, and it is possible to prevent the socket from being unable to be attached and the contact failure. Further, since a predetermined position of the conductor can be firmly fixed by dissolving a necessary and sufficient resin, it is possible to reliably prevent the conductor from detaching from the wiring portion due to an insufficient amount of the dissolution or rattling of the socket. .

Further, according to the rear combination lamp of the present invention, a wiring portion formed annularly along the edge of the socket mounting opening, and a wiring groove for wiring a conductor on the wiring portion. Welding ribs for fixing the conductor at both ends of the wiring groove near the outside of the wiring portion are formed integrally with the lamp body, and after the conductor is wired from the wiring groove to the welding rib. Then, the conductor is fixed by welding the welding rib. Therefore, the conductor is welded to the welding rib near the outside of the wiring portion, so that the resin does not flow into the socket mounting opening or the contact portion with the socket, and it is possible to prevent the socket from being unable to be mounted or the contact failure. In addition, since the predetermined position of the conductor can be firmly fixed, detachment of the conductor from the wiring portion, rattling of the socket, and the like can be reliably prevented. Also,
Wired in a fixed state from the wiring groove to a preset position,
Wiring work becomes easier and assembling work can be automated, and only the conductors and lamp body are required for wiring, so the number of parts can be greatly reduced, and the cost is greatly reduced. Reduction can be achieved.

In the rear combination lamp, the conductor is a linear conductor, and a part of the conductor laid in the wiring groove is exposed above the wiring groove.
The conductor contact portion of the connection terminal mounted in the socket makes elastic contact with the conductor with the mounting of the connection terminal in the lamp mounting opening. Therefore,
By attaching the socket to the lamp mounting hole, the connection terminal is reliably brought into contact with the conductor, and moves while contacting the locking position, so that a highly reliable rear combination lamp without poor contact can be obtained. .

In the rear combination lamp, after the conductor is wired from the wiring groove to the welding rib,
A press-fit rib for press-fitting the conductor at a position where the conductor is wired is formed integrally with the lamp body. Accordingly, the conductor is securely wired at a predetermined position, which facilitates the wiring work, and the press-fit rib is formed integrally with the lamp body, so that the number of parts is not increased.

In the rear combination lamp, the wiring groove is provided substantially linearly on the wiring portion, and the conductor is wired substantially linearly between the welding ribs at both ends of the wiring groove. Therefore, by sandwiching and welding a substantially linear conductor in the wiring groove between the welding ribs, the conductor is wired in a substantially straight line at a preset position, and there is no extra length, and the conductive material is provided at the time of wiring. There is no displacement of the body, and wiring work becomes easy. Also, since there is no need to make the wiring machine perform a complicated operation, it is possible to automate the assembling work,
Processing time can be reduced.

Further, in the rear combination lamp, if the wiring groove is set to a depth at which the conductor can be wired while being floated from the bottom surface, the entire conductor in the wiring groove becomes elastic. . Therefore, by attaching the socket to the lamp mounting hole, the connection terminal provided on the socket surely comes into contact with the conductor, and moves while elastically contacting the locking position, so that a contact failure does not occur, and the rear combination lamp does not occur. Can be further improved.
