BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lamp provided with a resin inner lens disposed in a housing and a resin outer lens mounted on an opening on the front surface of the housing.

[0002]

2. Description of the Related Art Conventionally, a vehicle lamp shown in FIG. 2 is known. In FIG. 2, reference numeral 1 denotes a housing having a front opening, and the housing 1 is fixed to a vehicle body (not shown) by a fixture 2.

In the housing 1, a leg 4 for mounting the first inner lens 3 made of resin is formed. An outer peripheral wall 5 is formed outside the leg 4, and the leg 4 and the outer peripheral wall are formed. There is a concave portion for filling the hot melt 6 between them.

[0004] The first inner lens 3 is attached to the leg portion 4, and a rear leg portion 7 a provided on the rear surface of the second inner lens 7 made of resin is brought into contact with the first inner lens so as to contact the first inner lens. 3 is fixed to the leg 4. Then, the outer lens 8 made of resin is attached to the front opening of the housing 1 with its rear surface in contact with a leg 7 b provided on the front surface of the second inner lens 7, so that the second inner lens 7 is connected to the outer lens 8. It is sandwiched and fixed with the first inner lens 3.

Mounting of the outer lens 8 is performed by filling a concave portion between the leg portion 4 and the outer peripheral wall 5 with a hot melt 6 and inserting the leg portion 8a of the outer lens 8 into the hot melt 6. It is.

[0006]

However, in such a vehicle lamp, the second inner lens 7 is sandwiched between the outer lens 8 and the first inner lens 3, so that the second inner lens 7 is vibrated by the vehicle. The second inner lens 7 rubs against the outer lens 8 and the first inner lens 3. As a result, white powder of the resin is generated, and if the white powder adheres to the outer lens 8, the white powder can be seen through the outer lens 8. Further, if the white powder is generated for a long period of time, the inner surface of the outer lens 8 is covered with the white powder, so that there is a problem that the light distribution performance is deteriorated.

The present invention has been made in view of the above circumstances, and an object of the invention is to provide a vehicle lamp that does not generate resin white powder due to vehicle vibration.

[0008]

According to the present invention, in order to achieve the above object, a first and a second inner lens made of a resin disposed in a housing and a resin made of a resin attached to an opening on a front surface of the housing are provided. A vehicle lamp having an outer lens, wherein the first and second inner lenses are fixed to a housing by pressing the first and second inner lenses with the outer lens. And a soft member interposed between the first inner lens and the second inner lens.
Characterized in that it was.

[0009]

According to the present invention, a soft member is interposed between an outer lens and a second inner lens and between a first inner lens and a second inner lens, and the first and second inner lenses are formed by the outer lens. Since the lens is pressed, the second inner lens does not rub against the outer lens or the first inner lens due to the vibration of the vehicle, and the resin white powder is not generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle lamp according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a resin housing having an open front surface.
To be fixed to the vehicle body 12. A lamp (not shown) is mounted in a lamp room inside the housing 10.

A leg 14 for mounting the first inner lens 13 made of acrylic resin is formed in the housing 10, and an outer peripheral wall 15 is formed outside the leg 14 so as to surround the leg 14. A gap 17 for filling the hot melt 16 is formed between the outer peripheral wall 15 and the outer peripheral wall 15.

The front surface of the first inner lens 13 is pushed by a rear leg portion 18a provided on the rear surface of a second inner lens 18 made of acrylic resin, and the first inner lens 13 is fixed to the leg portion 14. The rear leg 18a may be formed in an annular shape or may be formed partially. A soft resin member (soft member) 20, such as rubber, is engaged with the rear leg portion 18a.
8a and the front surface of the first inner lens 13.

The resin member 20 includes a contact piece 20a that contacts the tip end surface of the rear leg 18a, and a contact piece 20b that is formed continuously with the contact piece 20a and contacts the outer peripheral surface of the rear leg 18a. Have.

A front leg portion 18b extending forward is formed on the front surface of the second inner lens 18, and a soft resin member 21 is engaged with the front leg portion 18b. The resin member 21 is interposed between the front leg portion 18b and the rear surface of the outer lens 22 made of acrylic resin.
The inner lens 18 is pressed by the outer lens 22 via the resin member 21.

The resin member 21 has a contact piece 21a that contacts the tip end surface of the front leg 18b, and a contact piece 21b that is formed continuously with the contact piece 21a and contacts the outer peripheral surface of the front leg 18b. I have.

A leg 22a is formed rearward at the peripheral end of the outer lens 22. The leg 22a is inserted into the gap 17 filled with the hot melt 16, and the hot melt 1
The outer lens 22 is attached to the housing 10 by the rim 23. Note that the legs 18a, 18b, 2
2a may be formed annularly or partially.

A soft resin member is provided between the rear leg portion 18a of the second inner lens 18 and the front surface of the first inner lens 13, and between the front leg portion 18b of the second inner lens 18 and the outer lens 22. Since the lenses 20 and 21 are interposed, the lenses 13, 18, and 22 do not rub against each other due to the vibration of the vehicle to generate white resin powder.

When assembling the lamp, after filling the gap 17 of the housing 10 with the hot melt 16, the outer lens 22 is attached to the housing 10. At this time, the inner diameter of the contact piece 21 b of the resin member 21 is adjusted. By setting the outer diameter of the tip of the front leg 18b of the second inner lens 18 to be slightly smaller than the outer diameter of the second inner lens 18,
Can be temporarily fixed to the outer lens 22, thereby facilitating assembly to the housing 10.

Incidentally, if the second inner lens 18 is not temporarily fixed to the outer lens 22, the second inner lens 18 is pressed by the outer lens 22 and is fixed to the housing 10, so that the outer lens 22 is The second inner lens 18 is likely to fall when attached to the lens 10. For this reason, it must be re-assembled every time it falls, and it takes a lot of time and effort to assemble it.

Although the above embodiment has been described with reference to the case where the number of inner lenses is two, it is needless to say that the invention may be applied to the case where the number of inner lenses is one.

[0022]

According to this invention, a soft member is interposed between the outer lens and the second inner lens, and between the first inner lens and the second inner lens, and the first and second inner lenses are separated by the outer lens. Since the second inner lens is pressed, the second inner lens does not rub against the outer lens or the first inner lens due to the vibration of the vehicle, and the resin white powder is not generated.
