５の後端から引出されたコードである。 Conventionally, in this type of vehicle lamp, the bulb and bulb socket are located approximately at the first position relative to the lamp body.
It was installed in the configuration shown in the figure. To briefly explain this, what is indicated by the reference numeral 1 in the figure is a lamp body whose inner surface is formed as a reflective surface, and the back side (upper part in the figure) of the lamp has a cylindrical shape with a bulb insertion hole 1a formed therein. A holder portion 2 is integrally formed. 3 is a bulb used as a light source for this lamp, in this case a halogen lamp that is even brighter than an incandescent bulb. This bulb 3 is provided with two terminals 3b on the end face of a base portion 3a at the rear end, and a flange portion fitted into the holder portion 2 of the lamp body 1 at a portion near the tip of the base portion 3a. 4, and a plurality of (three in this example) engaging protrusions 4a are provided protruding from the periphery (see FIG. 2). Reference numeral 5 denotes a cylindrical valve socket into which the mouthpiece 3a of the above-mentioned valve 3 is fitted and held, and an insulator and a coil spring (both not shown) are built inside the socket. Similar to the side flange portion 4, a flange portion 6 is integrally formed with locking protrusions 6a protruding from three locations on its periphery. Note that 7 in the figure is a cord drawn out from the rear end of the valve socket 5.

た。 However, in the conventional vehicle lamp having such a configuration, the holder portion 2 of the lamp body 1 has a locking groove 8 corresponding to the engaging projection 4a of the bulb 3, and a locking groove 8 corresponding to the locking projection 6a of the bulb socket 5. Since the J-slot 9 is formed, the molding die is not only complicated, but also the molding process is troublesome, and the strength of the holder portion 2 is also unfavorable. Also,
Since it is installed by rotating the valve socket 5, the valve 3 and valve socket 5
Positioning accuracy is also required, and there is also the risk that the engaging protrusion 4a on the valve 3 side will be inserted into the J slot 9 side, resulting in incorrect assembly.

のである。 The present invention was devised in view of these circumstances, and is achieved by simultaneously inserting the engaging protrusion on the bulb side and the locking protrusion on the bulb socket side into the holder part of the lamp body and rotating it by a predetermined angle. The simple and inexpensive structure of forming a J-slot-shaped locking groove that can lock both protrusions simplifies the structure of the mold for molding the holder part of the lamp body, making the molding process easy and improving strength. To provide a vehicular lamp which is excellent in terms of performance, is inexpensive in terms of cost, allows bulb assembly work to be performed extremely easily and reliably, and is free from the risk of causing problems such as incorrect assembly. .

Then, when the valve socket 5 is rotated by a predetermined angle while being pressed,
Slide the engaging protrusion 4a on the bulb 3 side on the inclined surface 11a of the locking groove 11, enter the groove 11, and insert it into the fitting groove 10a on the front side of the lamp out of the fitting part 10 formed at the terminal end of the groove 11. It will fit and be fixed in place. On the other hand, the locking protrusion 6a on the side of the bulb socket 5 similarly reaches the terminal end of the locking groove 11, and the fitting groove 10 formed on the rear end side of the lamp serves as a fitting portion 10.
b and is fixed in place. In this case, the locking groove 1
A pair of fitting grooves 10a and 10b forming a fitting part 10 at the terminal end of the bulb socket 1 are formed to face each other in the front-rear direction of the lamp, and the respective protrusions 4a and 6a are moved by the force of the spring in the bulb socket 5, respectively. Fitted into corresponding fitting grooves 10a and 10b.
