DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a lamp mounted on a vehicle such as an automobile, and more particularly to a lamp suitable for mounting a lamp mounted on a corner of a vehicle body such as a turn signal lamp or a side lamp. Mounting structure.

[0002]

2. Description of the Related Art Various types of lamps are mounted on the body of an automobile. For example, a relatively heavy lamp such as a headlamp is fixed by fastening fixing bolts to the body. In general, headlamps have a relatively large mounting space, so the fixing bolts are placed inside the hood or on the back of the bumper so that the fixing bolts cannot be seen from the outside. It is relatively easy to improve the surrounding appearance.

[0003] Also, relatively small lamps such as turn signal lamps and side lamps provided at the front or rear corners of the vehicle body can be fixed by fastening fixing bolts to the vehicle body side. However, the area around the mounting portion of such lamps is often narrow, and if the mounting structure is designed in consideration of the fastening workability of the fixing bolt, it becomes difficult to treat the fixing bolt so that it cannot be seen from the outside. Conversely, if the fixing bolt is treated so as not to be seen from the outside, the fastening workability of the fixing bolt is reduced.

Incidentally, relatively small lamps such as turn signal lamps and side lamps are lightweight, so that the mounting structure thereof can be made relatively simple. Therefore, various mounting structures for such a relatively small lamp have been proposed. For example, Japanese Utility Model Publication No. 2-112225 (hereinafter referred to as a first prior art) discloses a side lamp installed between a headlamp and a vehicle body fender outside the headlamp, in which a fixing bracket is provided on an upper portion on the back side of the sidelamp. Attach the fixing bracket to the upper bracket on the headlamp side with screws, attach an elastic pressing piece that elastically contacts the inner surface of the vehicle body fender on the upper rear side of the side lamp, and bend the tip part on the lower rear side of the side lamp An elastic connecting piece formed and elastically urged toward the headlamp side is attached, a bent end portion of the elastic connecting piece is engaged with an engaging hole of a lower bracket on the headlamp side, and a lower part of the side lamp is further attached to the body fender. Discloses a mounting structure for a side lamp for an automobile, which is fixed with screws.

According to this technique, it is possible to easily and quickly attach and detach the side lamp, and to improve the appearance from the front of the lamp because bolts and screws are not visible on the front of the lamp. become. Japanese Utility Model Publication No. 4-6347 (hereinafter referred to as a second prior art) discloses a turn signal lamp which is mounted so as to fit into an opening formed in a vehicle body. And a peripheral portion of the opening is elastically held by the first leaf spring and the back surface of the turn signal lamp.
A second leaf spring, which is bent at the other end on the back side of the turn signal lamp, is provided, and the bent portion of the second leaf spring is elastically deformed to enter the opening while slidingly contacting the periphery of the opening. A technique has been disclosed in which a free end of a bent portion is inserted into a hole formed in a peripheral portion of the opening and locked to attach a turn signal lamp to a vehicle body.

According to this technique, the turn signal lamp can be mounted very simply and quickly using a leaf spring without using a bolt, and the appearance around the lamp can be improved. become.

[0007]

However, in the case of the first prior art, since the mounting structure such as mounting via a plurality of brackets is complicated, the accuracy of the shape and mounting of each bracket and the like is required. Even if the accuracy is high and there is no problem in mounting the lamp, the error in the mounting position of the lamp is likely to be large, and the appearance may be deteriorated. Further, since screws are visible on the side of the lamp, there is a problem that the appearance from the side of the lamp is impaired.

Further, in the case of the second prior art, the lamp can be easily and quickly mounted, and the appearance around the lamp is improved. However, since the mounting structure is constituted only by the leaf spring, it is difficult to secure the supporting rigidity of the lamp. In addition, the error in the mounting position of the lamp is likely to be large, which may cause a deterioration in appearance. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and can easily and quickly mount a lamp with sufficient support rigidity, and further enhance the accuracy of the lamp mounting position to improve the appearance around the lamp. It is an object of the present invention to provide a lamp mounting structure that can be used.

[0009]

Therefore, in the lamp mounting structure according to the first aspect of the present invention, a fitting portion provided at one end of the lamp casing on the back surface side of the lamp is connected to the first lamp mounting portion on the vehicle body side. The lamp is attached to the vehicle body by engaging a locked portion provided on the other end side of the lamp casing with a second lamp mounting portion on the vehicle body side. At this time, the abutting portion provided on the locked portion is brought into contact with a rib protruding from the second lamp mounting portion and extending in the height direction of the vehicle body. The portion is provided with a height regulating guide extending in a direction substantially perpendicular to the longitudinal direction of the rib, so that the contact portion is restricted from moving in the height direction of the vehicle body by the height regulating guide. Become like
