DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. 1 and 2 show an embodiment of a vehicle room lamp device according to the present invention. FIG. 1 is a sectional view thereof, and FIG. 2 is an exploded perspective view of a main part thereof. FIG.
3 is an enlarged sectional view of a portion corresponding to the line AA in FIG. 3, as in FIG. Therefore, FIG.
In FIG. 2 and FIG. 2, the same reference numerals as in FIG. 3 indicate the same as those in FIG.

In FIG. 1 and FIG.
3 is equivalent to the room lamp 100 shown in FIG. 3, and includes a lamp housing 3 having a bulb 2 disposed therein, and a lens 4 attached to the front side of the lamp housing 3. It is composed of a body 5 and a bracket 6.

More specifically, the lamp housing 3 is made of resin and is formed in a box shape, and a flange-like portion 3b is integrally formed on a peripheral surface on a front end side of the main body portion 3a. Locking holes 7a and 7b are formed on a pair of opposing side surfaces of the main body 3a, respectively. The locking hole 7
As shown in FIG. 2, a and 7b are formed with their positions shifted from each other in the horizontal direction. The lens 4 is attached so that the front surface of the flange portion 3b of the lamp housing 3 is covered.

The lamp body 5 has a molded ceiling 102.
And a lamp mounting hole formed in the molded ceiling 102 with an inner diameter larger than the outer diameter of the main body portion 3a of the lamp body 5 and smaller than the outer appearance of the flange-shaped portion 3b. Reference numeral 8 is provided corresponding to a portion to which the lamp body 5 is attached. further,
In the molded ceiling 102, the entire periphery of the lamp mounting hole 8 protrudes upward, and a concave portion 9 (see FIG. 1) for embedding the lens 4 is formed in this portion.

The bracket 6 is used for integrating the lamp body 5 and the molded ceiling 102 and for attaching the integrated lamp body 5 and the molded ceiling 102 to the roof bow 101. And this bracket 6
Is formed by bending a metal-made elastic band-shaped material, and is formed by bending one end of the lamp body 5 at a substantially right angle in a state where it can be inserted into the locking holes 7a and 7b of the lamp body 5. 6
a and a clip 6b formed by forming a corner at the other end and bending it into a substantially rhombic cross section. Also,
The locking portion 6a has a projection 10 for obtaining a press-fit state when the locking portion 6a is inserted into the locking holes 7a and 7b of the lamp body 5, facing downward from the lower surface of the locking portion 6a. It is formed in a slightly protruding state.

On the other hand, an engagement hole 11 is formed at a position corresponding to the clip portion 6b on the roof bow 101 side to which the bracket 6 is attached.

Next, the procedure for mounting the lamp body 5 will be described. First, after the lamp body 5 is attached to the molded ceiling 102, the lamp body 5 and the roof bow 10 are mounted together with the molded ceiling 102.
In the case where the lamp body 5 is mounted on the molded ceiling 102, the main body 3a is inserted from below the molded ceiling 102 into the lamp mounting hole until the flange 3b is brought into contact with the lower surface of the molded ceiling 102. 8 Then, when the flange-shaped portion 3b comes into contact with the lower surface of the molded ceiling 102, the back surface of the molded ceiling 102 and the locking holes 7a, 7
b corresponds exactly.

Further, in this state, on the back side of the molded ceiling 102, the locking portions 6a are respectively pressed into the locking holes 7a and 7b, and the brackets 6 are attached with the clip portions 6b protruding upward. . Then,
The lamp body 5 is prevented from falling out of the molded ceiling 102, and the lamp body 5 is attached to the molded ceiling 102.

Next, after the lamp body 5 is electrically connected, the molded ceiling 102 to which the lamp body 5 is attached is strongly pressed against the roof bow 101 with the clip portion 6 corresponding to the engagement hole 11. Then, the clip portion 6 is engaged with the engagement hole 11 while elastically deforming the clip portion 6.
And is clip-engaged as shown in FIG.
Thereby, the lamp body 5 and the molded ceiling 102 are attached to the roof bow 101 via the bracket 6.

Therefore, in the structure of this embodiment, the brackets are provided on the rear surface side of the molded ceiling 102 at the locking holes 7a and 7b of the lamp body 5 protruding to the rear surface side of the molded ceiling 102 through the lamp mounting hole 8. When the engaging portion 6a of the lamp body 6 is engaged, the lamp body 5 is retained and held against the molded ceiling 102.
And the molded ceiling 102 are integrated. When the clip portion 6b of the bracket 6 is further inserted into the engagement hole 11 of the roof bow 101 to engage with the clip, the integrated lamp body 5 and the molded ceiling 102 are attached to the bracket 6
Can be attached to the roof bow 102 with one touch. And use this part as a temporary fixation of the molded ceiling to the roof,
Thereafter, when the molded ceiling is permanently fixed to the roof portion, the mounting work of the molded ceiling is simplified. In the case where the bulb 2 and the like are replaced after the assembly, although not shown, only the lens 4 can be removed and replaced.

[0026]

As described above, according to the automotive room lamp device of the present invention, the lamp body protruding from the rear side of the molded ceiling through the lamp mounting hole is provided with a bracket on the rear side of the molded ceiling. By engaging the locking part of
When the lamp body is retained and held against the molded ceiling, the lamp body and the molded ceiling are integrated via this bracket, and further, when the clip portion of the bracket is inserted into the engagement hole of the roof bow and engaged with the clip, Since the integrated lamp body and molded ceiling can be attached to the roof bow with one touch via this bracket, the work of assembling the lamp body and the molded ceiling into the roof can be simplified. Further, since the attachment of this portion can be used as a temporary fixation of the molded ceiling to the roof portion, it is possible to expect an effect such as an easy operation when the molded ceiling is permanently fixed to the roof portion.
