Further, the necessity of using a tool every time the valve 92a is exchanged not only gives the user of the vehicle a feeling that the operation is complicated, but also makes it difficult for the user of the vehicle to use this kind of tool. If the work is unfamiliar with the work, for example, the screws 94 are likely to be lost during the work, and there is also a problem that it is difficult to maintain the quality, and solving these points is an issue. Was.

[0007]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, a lamp guard and a reflector unit are detached from a housing when a housing is fixed to a vehicle body and a bulb is replaced. In the vehicle lighting device, the housing and the reflector unit are fixed by providing a housing portion hook on the housing side and a rubber packing on the back surface of the reflector unit. The unit hook is engaged with the front surface of the reflector unit, and the housing and the reflector unit are fixed to the lamp guard by providing a guard hook provided on the lamp guard side and engaged with the housing at a position overlapping the housing unit hook. At the same time, the housing The surface of the click-side solves the problem by providing a vehicle lamp, wherein the pressing rib for restricting the movement of the spreading direction of the housing portion a hook is provided.

[0008]

Next, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and 2 is a vehicle lamp according to the present invention. The vehicle lamp 1 is a reflector unit 3 in which a housing 2, a bulb 31, a reflecting mirror 32, and a lens 33 are assembled. When,
It is the same as the conventional example in that it is constituted by the lamp guard 4.

Further, the housing 2 is fixed to the vehicle body or the like, and when replacing the bulb 3a, the lamp guard is first removed, and then the reflector unit 3 is removed from the housing 2 as in the prior art. However, in the present invention, the housing 2 is provided with the housing portion hook 2a, and the housing 2 is attached to the reflector unit 3 by hooking.

At this time, the housing portion hook 2a
Is extended forward from the housing 2 and can be hooked on a unit hook 3a provided on the reflector unit 3. At the same time, a rubber packing 5 is provided on the back surface of the reflector unit 3. At the same time, a waterproof rib 2b is provided at a position corresponding to the rubber packing 5 of the housing 2.

When the housing hook 2a is hooked on the unit hook 3a, the waterproof rib 2b
Compresses the rubber packing 5, and the repulsive force of the rubber packing 5 further securely holds the housing 2 and the reflector unit 3, and furthermore, the housing 2 and the reflector unit 3. Waterproofing between them is also ensured.

Further, since the housing 2 and the reflector unit 3 are engaged with each other by the housing hooks 2a, no tools are required for removing the housing 2 and the reflector unit 3 and assembling them. Even a simple operator can easily replace the valve 31.

In addition to the above, in the present invention, the lamp guard 4
The guard hook 4a provided on the housing 2 is also devised. The guard hook 4a is hooked on a housing hook 2c provided on the back surface of the housing 2, and the lamp guard 4 is mounted. This is the same as the conventional example, but according to the present invention, the housing hook 2a
Are provided as overlapping positions.

A pressing rib 4b is provided on a surface of the guard hook 4a on the housing hook 2a side, and the pressing rib 4b projects toward the housing hook 2a. (The guard hook 4a side).

By forming the guard hooks 4a in this manner, if the housing hooks 2a are expanded due to the vibration or impact of the vehicle during traveling, the holding of the reflector unit 3 becomes insufficient and the falling off occurs. In the event that the housing portion hook 2a is
Since the movement in the spreading direction is restricted by a, the occurrence of the above-described dropping can be avoided.

Further, with the above-described structure, even if the housing portion hook 2a is not sufficiently engaged with the reflector unit 3 due to, for example, inexperience of an operator in replacement work of the bulb 31, the lamp guard 4 can be replaced. At the time of mounting, the housing portion hook 2a is pushed inward by the rib 4b of the guard portion hook 4a, whereby sufficient hooking is performed.

Further, according to the present invention, the mounting of the reflector unit 3 to the housing 2 and the mounting of the lamp guard 4 are all carried out by hooking both hooks 2a, 4a. Therefore, it is not necessary to secure a space for operating the tool, and therefore, the vehicle lamp 1 has a greater degree of freedom in selecting a position when mounted on the vehicle body.

[0018]

As described above, according to the present invention, the housing and the reflector unit are fixed by providing a housing part hook on the housing side and a rubber packing on the back surface of the reflector unit, and by using the elasticity of the rubber packing. The housing portion hook is engaged with the front surface of the reflector unit, and the housing and the reflector unit are fixed to the lamp guard by providing a guard portion hook provided on the lamp guard side and engaged with the housing at a position overlapping the housing portion hook. On the surface of the guard hook on the side of the housing hook, a holding rib for restricting the movement of the housing hook in the spreading direction is provided. Space for operating the tool beside the vehicle lamp It gives flexibility in the selection of the mounting positions reserved as required, in which excellent effects in improving the practicality.

Second, since the use of the above-mentioned tool is not required, even a person who is unfamiliar with this kind of work, such as a vehicle user, can perform only a simple work of hooking and removing both hooks. The operation can be simplified because the valve can be replaced, and the effect of improving the practicality can be obtained in this aspect as well. At the same time, the operation can be ensured by the holding rib.
