Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp provided with an elastic protector along a lamp mounting opening of a vehicle body.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
There is a vehicle lamp including a headlamp 2 and a front turn signal lamp 3 adjacent to the headlamp 2 in front of (not shown).

The front turn signal lamp 3 is shown in FIG.
As shown in (B), the housing 4 and the lens 5 that closes the front opening 4 a of the housing 4 are provided.

The housing 4 follows the opening shape of the lamp mounting opening 7 formed by the edge portion 6a of the fender panel 6 and a bumper (not shown). Further, in the housing 4, a bent flange portion 4c forming a groove portion 4b along the front opening 4a and a flange portion 4d extending along the edge portion 6a and protruding outward from the tip of the bent flange portion 4c. And are formed.

An elastic protector 9 made of an elastic material such as rubber is fixed to the flange portion 4d via an adhesive agent 8.

The elastic protector 9 closes the space S between the edge portion 6a and the front turn signal lamp 3 to improve the appearance and prevent water droplets from entering the vehicle body 1.

Therefore, since the elastic protector 9 surely closes the space S even when an error occurs in the dimension of the lamp mounting opening 7 due to an error in the molding of the fender panel 6, the space S can be closed. The size and the shape are formed in consideration of the case where the dimensional error occurs in the widening direction, and the elasticity is set in consideration of the case where the dimensional error occurs in the narrowing direction of the space S.

On the other hand, in the lens 5, the leg portion 5a protruding from the inner surface of the lens 5 faces the groove portion 4b of the housing 4, and the groove portion 4b is formed.
It is held in the housing 4 in a state in which it is in contact with a sealing material 10 such as a hot melt material filled in the housing 4 to ensure hermeticity.

[0009]

By the way, in the front turn signal lamp 3 as the vehicular lamp constructed as described above, the elastic protector 9 is fixed to the flange portion 4d via the adhesive 8. .

Therefore, there are many work steps such as a work step of applying the adhesive 8 to the flange portion 4d or the elastic protector 9, a work step of mounting the elastic protector 9 on the flange portion 4d, and a work step of putting the adhesive 8 into a coin. Moreover, not only is it time consuming and the working cost rises, but also an expensive adhesive 8 has to be used to bond different materials such as the housing 4 which is a resin and the elastic protector 9 which is a rubber, There has been a problem that the material cost also rises.

Further, the allowable range of the elastic protector 9 with respect to the dimensional error of the fender panel 6 becomes narrow depending on its size, shape and elasticity, and moreover,
When the space S is narrowed due to a dimensional error of the fender panel 6, the contact portion with the edge portion 6a is crushed and a bead-shaped raised portion P is generated, resulting in a problem that the appearance is impaired.

The present invention has been made in view of the above circumstances, and it is inexpensive and surely closes the space between the lamp body and the lamp mounting opening and improves the appearance even when a dimensional error occurs. It is an object of the present invention to provide a vehicular lamp capable of achieving the above.
