Description

[Detailed explanation of the invention] This invention aims to preserve the shape of vehicle lighting equipment, especially the rim part, and aims to prevent deformation of the lighting equipment itself and improve its appearance by adjusting the appearance. The purpose is to

Regarding the conventional shape-retaining means used in this type of vehicle lamp, as shown in the cross-sectional view of the main part in FIG. The rim R is integrally formed with a V-shaped top, and the leg l of the lens L is pressed into contact with the gasket g loaded in the groove C to maintain the sealing. Like V
Since it has a folded shape, it is mechanically weak, and after casting in the manufacturing process, the outside of the rim R portion deforms as shown by the dotted line and the symbol R' in the figure, spoiling its appearance.

However, in order to prevent such adverse effects from cancer, a plurality of plate-shaped ribs Rb are integrally molded in the rim R at appropriate intervals from the front to the back in the figure. After construction, rim R along rib Rb
Sink marks occur on the outside of the product, creating a line-shaped depression that spoils the appearance. However, without the rib Rb, as mentioned above, the rim R would be mechanically weak, the tip would swing and deform, giving it a delicate feel, and the product itself would lose reliability. There are drawbacks.

The present invention aims to solve the above-mentioned drawbacks by simple means, and the specific structure of an embodiment thereof will be described in detail below with reference to FIG. 2. Note that the same parts as shown in FIG. 1 are given the same reference numerals, and redundant explanations will be omitted.

In FIG. 2, K is a substantially T-shaped locking piece that is made of the same resin as the lamp body B and is separate from the lamp body, and its tip t is in contact with the inner bottom of the rim R. , its both ends t' are formed so as to come into contact with the outside of the lamp body B and the inside of the end of the rim R.

The present invention has the above-mentioned configuration.Next, we will discuss the mounting mode and the operation and effect of the lens L.
It is best to assemble the lamp body B to the lamp body B in the conventional manner, and insert the locking piece K from the rear of the rim R so that its tip t fits into the bottom of the rim. Both ends t' of the piece K are elastically abutted against the inside of the opening of the rim R so that the rim is maintained in its normal shape. In this way, the required number of locking pieces K may be loaded.

According to the present invention, as described above, the operation is extremely simple and the workability is good, and the shape of the locking piece K is T-shaped, and the opening of the rim is formed at both ends t and t'. Since the inner side is elastically held in contact and the tip t is fitted and fixed to the bottom of the rim R, so to speak, it is configured to make three-point contact, so after loading, it maintains stable mechanical strength for a long time. Not only can the rim be sufficiently maintained, but also the deformation that occurs after casting can be corrected, and as a matter of course, there is no sink mark that occurs on the outside of the rim R as seen in conventional types. , will be effective enough to achieve the purpose of this proposal.

Note that if there is a risk that the locking piece K during loading may move due to vibrations during transportation, the locking piece K will be moved as shown by dotted lines in FIG. A protrusion t″ is provided on one side of the tip t of the
Correspondingly, it is preferable to form an engagement hole h on the outer periphery of the lamp body B, and by doing so, the loading of the locking piece K becomes even stronger.
