<Conventional technology> Automotive lighting equipment installed inside the car, such as high-mounted stop lamps and interior lamps, does not need to be waterproof, and it also reduces material costs and improves moldability and assembly workability. It is preferable that the vehicle mounting surface side, such as the bottom of the cover, be open. However, as shown in FIG. 5, if the bottom part (vehicle body mounting surface side) 1a of the cover 1 is opened continuously from the front opening, the lens 2 or lens mounting frame 3 attached to the front opening of the cover 1 will be removed. is engaged and supported only by the upper wall 1b of the front opening, especially against loads (vibrations) in the vertical direction; Now, the upper wall 1 of cover 1
Since the engaging protrusion 21 protruding from the lens or lens mounting frame 3 is simply engaged with the engaging opening 20 formed in b, the lens or lens mounting frame may be moved from the front opening of the cover due to external vibrations, etc. There was a problem in that it was easy to fall off, and there was also a problem in that light leaked from the engaging portion to the outside.

<Problems to be solved by the invention> The present invention was made in view of these conventional problems.Even if the bottom of the cover (on the side where the vehicle body is attached) is opened continuously with the front opening, the lens cannot be removed. Alternatively, to provide an automobile lamp in which a lens mounting frame can be securely attached to a front opening of a cover, and there is no risk of light leaking to the outside from the engagement portion between the front opening of the cover and the lens or the lens mounting frame. This is what I am trying to do.

<Means for Solving the Problems> The automotive lamp of the present invention that achieves the above purpose includes installing a resin lens or lens mounting frame in the front opening of a resin cover, and connecting the cover and the lens or lens mounting frame. In the automotive lighting device, the bulb is installed in a room defined by: the bottom of the cover is opened continuously with the front opening, and the front opening edge of the cover and the lens or lens attachment. An engaging wall and a fitting recess that engage with each other are formed on the peripheral edge of the frame, and a plurality of cuts are formed in the engaging wall to form a plurality of elastic engaging pieces, and the fitting recess is formed with a plurality of cuts. The groove is characterized in that a locking protrusion that engages with the elastic engagement piece is provided on the inner surface of the outer wall constituting the groove.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The cover 1 is molded into a desired shape using a resin material, and the bottom part 1a, which is the side to which the vehicle body is attached, is formed in an open shape so as to be continuous with the front opening, and the lens 2 is directly attached to the front opening.

Alternatively, an engaging wall 7 and a fitting groove 8 that engage with each other are formed on the peripheral edge of the lens mounting frame 3, and a plurality of cuts 9 are formed in the engaging wall 7 to provide a plurality of elastic engagements. A locking protrusion 11 that engages with the elastic engagement piece 10 is provided on the inner surface of the outer wall 8a constituting the fitting groove 8. That is, when the lens 2 is directly attached to the front opening of the cover 1 without using the lens attachment frame 3, it is attached to the front opening edge of the cover 1 and the periphery of the lens 2, and when the lens attachment frame 3 is used, is an engagement wall 7 that engages with the front opening edge of the cover 1 and the periphery of the lens mounting frame 3, respectively.
According to the illustrated embodiment, an engaging wall 7 is extended to the edge of the upper wall 1b constituting the front opening of the cover 1, and a fitting groove 8 is formed in the lens mounting frame 3. An example in which a fitting groove 8 is formed on the upper periphery will be described. That is, the engagement wall 7 is formed to protrude forward in an appropriate width along the edge of the upper wall 1b constituting the front opening of the cover 1. A plurality of elastic engagement pieces 10 that engage with the elastic engagement pieces 11 are formed. At this time, an engaging pawl 10a is formed protruding from the tip of each elastic engaging piece 10, and cuts 9 are formed on both left and right sides of each elastic engaging piece 10 to make the elastic engaging piece 10 flexible. This imparts springiness. Furthermore, the fitting groove 8 has an outer wall 8a that also serves as the outer peripheral wall of the lens mounting frame 3, and an inner wall 8b that also serves as a light leakage prevention wall that is parallel to the outer wall 8a and has a sufficiently wide projecting width than the outer wall 8a. With that said,
The outer wall 8a of the fitting groove 8 is formed into a groove having approximately the same length as the entire length of the engaging wall 7 and slightly wider than the wall thickness of the engaging wall 7 and having a substantially U-shaped cross section.
A locking protrusion 11 is formed protrudingly on the inner surface to engage the engaging claw 10a protrudingly provided on the elastic engaging piece 10 of the engaging wall 7, and the inner wall 8b is provided with the elastic engaging piece 10 of the engaging wall 7. An elastic engagement piece 10 is located at a position corresponding to the piece 10.
A slightly wider notch 12 is formed. By forming this notch 12, the engagement wall 7
