果を得るようになつている。<Prior art> As a vehicle lamp, a heat shield plate is provided on the inner wall of the resin cover body and housing that make up the lamp body to avoid damage to the cover body and housing due to the radiant heat of the lamp bulb. It is known that this was done. An example of a heat shield mounting structure is shown in FIG. 5. In this method, a projection 2 is integrally formed on the inner wall of a lamp body 1, a mounting hole 4 is formed in a heat shield plate 3, and after the projection 2 is inserted into the mounting hole 4, the penetrating end is heated or otherwise heated. The two are combined by crushing them into a shape. Furthermore, a pedestal portion 5 for receiving the heat shield plate 3 is formed on the outer periphery of the proximal end of the protrusion 2 . This pedestal part 5 fixes the heat shield plate 3 more strongly, and also functions as a spacer to separate the inner wall of the lamp body 1 and the heat shield plate 3, forming a gap between the two. It has come to have a high insulation effect.

る。 Further, FIG. 4 is a sectional view of a main part showing a mounting structure for a heat shield plate 17 according to another embodiment of the present invention.
The vehicle lamp according to this embodiment also has a structure substantially similar to that shown in FIG. 1, and the same members are denoted by the same reference numerals, and a description of the overall structure will be omitted. A spacer 22 is integrally formed on the periphery of the mounting hole 18 in the heat shield plate 17 . The spacer 22 is formed by burring and protrudes with a height corresponding to the distance between the cover body 11 and the heat shield plate 17 when they are joined.

い。 A protrusion 19 is formed on the cover body 11. When the protrusion 19 is inserted into the mounting hole 18 and the penetrating end is crushed, the spacer 22 is inserted into the inner wall of the cover body 11 and the penetrating end of the protrusion 19. It will be held between the Department and the Department. With this, heat shield plate 1
7 is properly fixed without causing any warping or the like. Moreover, since only the protrusions 19 are formed on the cover body 11, sink marks due to extreme thickening will not occur.

熱効果を高めることとなる。<Effects of the invention> According to the invention, since the heat shield plate can be fixed by being sandwiched around the entire periphery of the mounting hole, chattering noise due to warping or the like can be prevented, and a proper mounting state can be obtained. Further, there is no need to provide a pedestal section continuously at the base end of the protrusion, and sink marks due to excessive thickening can be prevented. In addition, by providing a bent part on the rear side of the lamp and forming an expanded part of the heat shield, the high-temperature air accumulated in the gap between the heat shield and the inner wall of the cover is diffused into the lamp chamber, improving the heat dissipation effect. It will increase it.
