There is a risk that this will be omitted.

In view of the above circumstances, the present invention allows for easy installation of the screw mounting and good workability, and after installation, the headlamp unit can be reliably fitted into the mounting hole and fixed to the mounting base. The object is to provide an advantageous headlamp mounting device.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings of FIGS. 3 to 7.

In this example, as shown in FIG. 3, the headlight unit 1 is supported at three locations on the mounting base 2, two of which are supported by the headlight mounting device 3 of the present invention, and the other one is supported by the headlight mounting device 3 of the present invention. This is an example in which a coil spring 4 stretched between the headlamp unit 1 and the mounting base 2 is used.

To be more specific, as shown in FIGS. 4 and 5, the headlight unit 1 includes a sealed beam lamp 11 and this lamp 1.

are formed in two places.

In this example, the mounting base 2 is a housing fixed to a vehicle body.

Of course, the mounting base 2 may be the vehicle body itself.

Attachment holes 21 are provided on the periphery of the attachment base 2 at positions corresponding to the ear pieces 14 described above.

The mounting hole 21 includes a rectangular large diameter hole 22 and a rectangular small diameter hole 2.
3 are arranged in series, and an engagement hole 24 is provided near the attachment hole 21.

Further, a hook portion 25 on the periphery of the coil spring 4 is hooked by a hook portion (not shown) of the coil spring 4.

The mounting device 3 described above includes an adjustment screw 30 and a screw mounting 33 made of synthetic resin.

The adjustment screw 30 has a head 31 at one end, and a collar 32 slightly spaced apart from the head 31.

The head 31 of the adjustment screw 30 is locked to the lug 14 of the mounting ring 13, and
The other end of the adjustment screw 30 is threaded into a screw mounting 33 attached to the mounting base 2.

Therefore, when the adjustment screw 30 is rotated, the lug 14 can swing between the head 31 and the collar 32, so that the optical axis of the headlamp unit 1 can be adjusted.

The screw mounting 33 has a flange portion 35 attached to one end side of the main body portion 34, as shown in FIG.
It consists of

The main body part 34 has a rectangular shape that can be inserted into the large diameter hole 22, and has an insertion hole 36 and a groove part 37 for attachment to the mounting base 2.

The insertion hole 36 gradually widens on the flange portion 35 side,
The adjusting screw 30 can be easily inserted into the housing, and there are four vertical protrusions 36a.

Further, although the groove portions 37 are formed on two opposing sides of the main body portion 34, they may be formed on the entire circumference of the main body portion 34.

Next, the flange portion 35 will be described.
A protruding piece 38 is integrally extended therein, and the protruding piece 38 has a locking protrusion 39, and the locking protrusion 39 is connected to the engaging hole 24.
By fitting into the screw mounting hole 21, the screw mounting 33 is prevented from being removed from the mounting hole 21.

To be more specific, the protruding piece 38 is made thinner than the flange portion 35, giving the protruding piece 38 flexibility.

To attach the screw mounting 33 thus formed to the mounting hole 21 of the mounting base 2, insert the main body 34 of the screw mounting 33 into the large diameter hole 22 as shown in the illustration in FIG. ) and protrusion 3
8 is bent upward and moved in the direction of the arrow to fit into the small diameter hole 23 in the groove 37 of the main body part 34.
4 is held between the mounting base 2.

Then, the locking protrusion 39 of the projecting piece 38 is fitted into and engaged with the engagement hole 24 of the mounting base 2 to prevent the main body portion 34 from moving toward the large diameter hole 22 side.

When the adjustment screw 30 is screwed into the insertion hole 36 of the screw mounting 33 installed in this way, the thread groove is formed in the protrusion 36a, the adjustment screw 30 is screwed into the main body 34, and the adjustment screw 30 The notch 14a of the ear piece 14 is inserted between the head and the collar 31 to engage the head with the ear piece 14, and the headlamp unit 1 is attached to the mounting base 2.

Therefore, since the screw mounting 33 is fixed after being installed in the mounting hole 21, there is no possibility of rattling caused by vibration or movement of the main body 34 when adjusting the optical axis, so that it can be moved forward in the set direction. Lighting unit 1
can be adjusted.

Furthermore, even if the headlamp unit 1 becomes larger, the screw mounting 33 does not move, so the screw mounting 33 can be prevented from coming out from the mounting base 2.

In the above embodiment, the retaining part 24 is formed to be located in front of the small diameter hole 23, but it may be formed on the side of the small diameter hole or behind the large diameter hole. As another example of the through hole, for example, the hole may be formed into a recess into which the locking protrusion 39 is fitted and engaged.

As is clear from the above implementation, the present invention includes a screw mounting that fits into the mounting hole of the mounting base, and an adjustment screw that is threadedly engaged with the screw mounting and whose head is locked to the headlamp unit. In the headlamp mounting device, the mounting hole is configured by connecting a large diameter hole and a small diameter hole, and an engagement hole is provided near the mounting hole, and the screw mounting is engaged with a main body portion having a groove. a flange portion extending from a protrusion having a locking protrusion, the protrusion having the locking protrusion being thinner than the flange portion and having flexibility, and the protrusion being bent upward; Since the groove of the main body part is fitted into the smaller diameter hole than the large diameter hole, and the locking protrusion of the projecting piece is engaged with the engagement hole, screw mounting can be performed without the need for a full-sized jig or tool. The main body can be fitted into the mounting hole of the mounting base, resulting in good workability.Moreover, the fitted body does not move toward the large diameter hole, making it easy to set the headlight unit. The light can be adjusted in the desired direction to obtain appropriate light distribution.

Furthermore, even if the headlamp unit becomes larger, it can be reliably mounted on the mounting base, providing an advantageous effect.
