Next, the present invention will be described in detail with reference to an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 denotes a vehicular lamp, and a housing 2 of the vehicular lamp 1 is formed in a pipe shape, and a cap body 3a and a leg 3b are respectively provided at openings 2a at both ends. This is similar to the conventional example in that the seal 3 is attached to both the housing 2 and the cap 3 so that the seal packing 4 is sandwiched between the housing 2 and the cap 3 for waterproofing.

Therefore, for example, if the inside diameter of the housing 2 is a perfect circle, three places at 120 ° intervals or four places at 90 ° intervals, and if the inside diameter of the housing 2 is rectangular, two places on each long side. It is provided at an appropriate position and in an appropriate number, such as a total of six places, one place on each short side, thereby achieving the purpose.

At this time, the leg 3b is in contact with the opening 2a of the cap body 3a so that the center axis X of the housing 2 is
Since the direction is kept parallel, the positioning projection 3c may be used only for maintaining the interval between the housing 2 and the leg 3b. Therefore, the length in the direction of the central axis X is not so large. Therefore, it is not necessary to cover the entire length of the leg portion 3b, and the leg portion 3b is formed as a very short one long enough to achieve the above-mentioned purpose.

With the above construction, when the housing 2 and the cap 3 are mounted, the gap between the inner diameter of the housing 2 and the leg portion 3b becomes uniform, so that the seal packing 4 sandwiched between the two is provided. The amount of compression of the convex portion 4a is also uniform over the entire circumference, thereby completely eliminating the cause of the deterioration of the waterproof performance, such as a partial compression amount shortage. Note that even when external stresses in different directions are applied to the housing 2 and the cap 3, there is no displacement due to the contact between the positioning protrusions 3 c and the waterproof effect is not impaired.

As described above, according to the present invention, according to the present invention, positioning protrusions for contacting the inner diameter of the housing are provided on the legs of the cap so as to make the gap between the housing and the legs uniform. A window portion is provided at a position corresponding to the positioning protrusion, so that the waterproof structure of the vehicular lamp is provided, for example, the cross-sectional shape of the housing, a manufacturing error, or both of the housing and the cap due to the application of external stress during use. The reduction in the waterproof effect due to the eccentricity is completely prevented by the action of maintaining the uniform distance between the two by the positioning projections, thereby eliminating the occurrence of water intrusion and improving the reliability of this type of vehicle lamp. This has an extremely excellent effect on the improvement of.
