DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp having an end rubber.

[0002]

2. Description of the Related Art Conventionally, in a vehicle lamp such as a rear combination lamp, in order to prevent the lamp from coming into contact with the vehicle body due to the vibration of the vehicle body when the lamp is assembled to the vehicle body, the noise is generated. There is known a device configured to interpose an end rubber between the lamp and a vehicle body. The end rubber is generally fixed to a peripheral portion of the lamp body, and is configured to be able to be somewhat elastically deformed when it comes into contact with the vehicle body.

[0003]

However, the lamp having the conventional end rubber mounting structure in which the end rubber is simply fixed to the peripheral portion of the lamp body has the following problems.

That is, as shown in FIG. 5, the end rubber 2 is fixed to the peripheral edge 6a of the lamp body 6 by bonding or the like. There is a problem that the end rubber 2 is easily peeled off from the lamp body peripheral portion 6a by the rain water, dust, and the like because the rain water, dust, and the like easily enter through the gap.

[0005] The present invention has been made in view of such circumstances, and when the lamp is mounted on a vehicle body,
It is an object of the present invention to provide a vehicular lamp capable of effectively preventing rainwater, dust, and the like from invading an end rubber fixing portion through a gap between a lens and a vehicle body.

[0006]

According to the present invention, the above object is achieved by devising the shape of the end rubber.

That is, according to the present invention, a lamp body having a front opening and a lamp body disposed in front of the lamp body and fixed to the lamp body around the front opening. In a vehicle lamp comprising a lens and an end rubber fixed to a peripheral portion of the lamp body, the end rubber contacts an outer end surface of a peripheral portion of the lens which faces the lamp body peripheral portion. It is provided so as to extend forward to a contact position.

The above-mentioned "end rubber" may be fixed to the entire periphery of the lamp body or may be fixed to a part of the lamp body as long as it is fixed to the peripheral portion of the lamp body. It may be.

The term "fixing" refers to fixing in a form that may be peeled off later, such as sticking, bonding, or sticking.

[0010]

As described above, in the vehicle lamp according to the present invention, the end rubber fixed to the peripheral edge of the lamp body has the end rubber on the outer peripheral surface of the peripheral edge of the lens facing the peripheral edge of the lamp body. Since it is provided so as to extend forward to the contact position, the end rubber fastening portion and the space in front of the lens are blocked by the end rubber, thereby preventing intrusion of rainwater, dust, etc. into the end rubber fastening portion. Will be done.

As described above, according to the present invention, it is possible to effectively prevent rainwater, dust and the like from entering the end rubber fastening portion through the gap between the lens and the vehicle body when the lamp is mounted on the vehicle body. can do. Thus, it is possible to minimize the occurrence of the problem that the end rubber peels off from the peripheral portion of the lamp body.

The above-mentioned "end rubber" has a specific structure provided that it is fixed to the peripheral portion of the lamp body and extends forward to a position in contact with the outer end surface of the peripheral portion of the lens. Although not particularly limited, as described in claim 2, the fixing is performed on the rear surface of the lamp body peripheral portion, and the end rubber is also brought into contact with the outer end surface of the lamp body peripheral portion. With this configuration, the end rubber fixing portion is double-blocked from the space in front of the lens by the outer end surface of the lens peripheral portion and the outer end surface of the lamp body peripheral portion. Intrusion into the fastening portion can be more effectively prevented.

[0013] In this case, as described in claim 3, the end rubber is formed with an engagement recess for engaging with a boundary corner portion between the outer end surface and the rear surface of the peripheral portion of the lamp body. For example, when the end rubber is fixed to the lamp body peripheral edge, the positioning of the end rubber with respect to the lamp body peripheral edge can be performed accurately and easily by engaging the engagement concave portion of the end rubber with the boundary corner portion of the lamp body peripheral edge. Thus, the end rubber fastening operation can be performed efficiently.

Further, as set forth in claim 4, the outer end face of the lamp body peripheral edge and the lens peripheral edge are formed stepwise, and a step corresponding to this step is formed on the end rubber. If formed, the path between the end rubber fastening portion and the space in front of the lens will be formed in a maze shape, so that entry of rainwater, dust, etc. into the end rubber fastening portion is further improved. Can be prevented.

[0015] In the above construction, as described in claim 5, if the end rubber is formed such that an extension extending outward from the lens is formed at an abutting portion of the end rubber in contact with the outer end surface of the lens. Since the elastic deformation of the end rubber at the contact portion can be relatively large, the risk of the lens being damaged by contact with the vehicle body can be reduced.

The shapes of the lamp body peripheral portion and the lens peripheral portion are not particularly limited, but both peripheral portions are formed in a flange shape extending substantially parallel to each other. And the fixing between the lamp body and the lens is performed such that a gap is formed between both peripheral edges thereof,
By employing the configuration of the present invention, the following operation and effect can be obtained in addition to the above operation and effect.

That is, when a gap is formed between the flange-shaped peripheral portions of the lamp body and the lens, rainwater, dust, and the like enter the gap between the both peripheral portions via the gap between the lens and the vehicle body. This causes the deterioration of the lamp and the appearance of the lamp. However, in the present invention, the gap between both peripheral portions and the space in front of the lens are formed by the end rubber contacting the outer end surface of the peripheral portion of the lens. And it is possible to effectively prevent rainwater, dust and the like from entering the gap.
