Then, each of the lamps 4 attached to the socket 5 is inserted into the lamp mounting hole 22 from the direction of the rear part 21, and the socket 5 is removably fitted into the lamp mounting hole 22, so that a large number of lamps 4 are arranged in a row. It is provided inside the lamp housing 2.

The printed circuit board 6 is attached to the back surface of the rear part 21 in the longitudinal direction, and is provided in a long length corresponding to the lamp housing 2, and has a large number of holes corresponding to the lamp mounting holes 22. There are several.

When the socket 5 is fitted into the lamp mounting hole 22, the 7 langes 50 at the rear end of the socket press the printed circuit board 6 toward the rear section 21, and the printed circuit board 6 is held between the socket 5 and the rear section 21. It is. Furthermore, the lamp 4 and the printed circuit board 6 are connected by the printed circuit board 6 and the flange 50 coming into contact with each other.

One end of the connection terminal 7 is press-fitted into a mounting hole a provided in the rear part 21, and the other end is bullet-shaped so that it can be detachably connected to the harness of the vehicle. . When press-fitting and fixing the connection terminal 7,
Both of the printed circuit boards 6 are press-fitted into the mounting holes a and connected to the printed circuit boards 6, and the printed circuit boards 6 are fixed to the rear part by the connecting terminals 7. Note that the printed circuit board may be soldered to the connection terminal instead of being press-fitted into the mounting hole. Furthermore, the printed circuit board may be fixed by heat crimping at a predetermined location at the rear.

A jetty 23 that surrounds the rear portion 21 is integrally provided on the outer peripheral edge of the rear portion 21 of the lamp housing 2, and a recessed portion is surrounded.

The gasket 8 is provided in a long length corresponding to the lamp housing 2, and is fitted into the recess formed around the lamp housing 2 to hide the socket 5 and the printed circuit board 6, that is, the rear portion 21, and The connection terminals 7 are inserted into the respective holes 80, and the area around the connection terminals 7 is sealed. A plurality of protrusions 81 extending in the circumferential direction are formed on the circumferential surface of the packing 8, and the cross-sectional shape of the curved surface is provided in a sawtooth shape.
