DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 4, the lower surface of the roof panel of the bus 10 is covered with a main ceiling 11, and a sub ceiling 12 is provided at a predetermined distance below the main ceiling 11 at the rear end of the passenger compartment. The sub-ceiling 12 protrudes toward the center of the passenger compartment, and is formed so as to rise so that a peripheral edge thereof is separated from the main ceiling 11 by a predetermined gap 13.

As shown in detail in FIGS. 1 and 2, the upper edge of the raised sub-ceiling 12 is mounted on the sub-ceiling 12 such that a light transmitting member 14 described later is attached to the sub-ceiling 12 so as to close the gap 13. It is formed by bending inward of the sub ceiling 12 so that the surface of the transmission member 14 and the outer surface of the sub ceiling 12 are substantially flush with each other. On the inner side surface of the sub ceiling 12, a light source mounting portion 12a extending substantially horizontally inward and a ceiling mounting portion 12b rising from the tip of the mounting portion 12a and abutting on the main ceiling 11 are integrated with the sub ceiling 12. Is formed. An illuminating lamp 16 is provided at a position on the light source mounting portion 12a that is not visible from the passenger compartment. The sub ceiling 12 is mounted at a predetermined position by fixing the upper end of the ceiling mounting portion 12b to the main ceiling 11 with bolts 15. Can be

A pair of luggage shelves 17, 17 are respectively provided to extend toward the center of the cabin along both side edges of the cabin lower than the main ceiling 11, and at the rear end of the luggage shelves 17, 17. A pair of speakers 18 and 18 are placed. The gap 13 is formed so that both ends thereof are curved toward one side surface of the speakers 18. 27 is a rear windshield glass, and 28 is a side windshield glass (FIGS. 3 and 4).

A characteristic configuration of this embodiment is that a light transmitting member 14 having a claw 19 which is engaged with an edge of the gap 13 and having both ends screwed to the sub ceiling 12 is attached so as to close the gap 13. (FIGS. 1 and 2). In this example, the light transmitting member 14 is a lens formed of a transparent acrylic resin, and both ends of the light transmitting member 14 are curved toward the pair of speakers 18 and 18 and abut on one side surface of each of the speakers 18 (see FIG. 3 and FIG. 4). Holes 14b are formed at both ends of the light transmitting member 14, respectively.

The claw 19 is formed of a resin, and is fixed to a back surface of the light transmitting member 14 via a pin 14a.
And an elastically deformable 2 formed integrally with the base 19a.
It has book locking portions 19b, 19b. A light transmitting member 14 is attached to the sub ceiling 12 so as to close the gap 13, and the upper end of the ceiling mounting portion 12 b facing the claw 19 is engaged with the light transmitting member 14 along the lower surface of the main ceiling 11. The stopper 21 is fixed by the pin 22. The distal end of the locked member 21 is bent downward so as to face the bent upper edge of the sub ceiling 12. Locking portions 19b, 19b of claws 19
Are locked between the upper edge of the sub ceiling 12 and the tip of the locked member 21 (FIG. 2).

A bracket 23 facing the light transmitting member 14 is fixed to the ceiling mounting portion 12b facing the hole 14b of the light transmitting member 14 with the light transmitting member 14 mounted in the gap 13. A nut 26 to which the pan head screw 24 is screwed is welded to the surface opposite to the surface facing the light transmitting member 14 (FIG. 1).

The light transmitting member 14 of the indirect lighting apparatus thus configured is temporarily fixed at a predetermined position by locking the claws 19 at the edges of the gap 13. The light transmitting member 14 is securely attached to the sub ceiling 12 by inserting the pan screw 24 into the hole 14b and screwing it into the nut 26 welded to the bracket 23. As a result, since the gap 13 is closed by the light transmitting member 14, it is possible to prevent a passenger from inserting his / her hand into the inside of the sub ceiling 12 from the gap 13, pushing a foreign object, or invading dust.

The light emitted from the illumination lamp 16 is reflected by the main ceiling 11 and passes through the light transmitting member 14 or the light transmitting member 14
The vehicle is illuminated by being reflected by the main ceiling 11 after passing through the vehicle, and the luminous light illuminates the vehicle interior, so that the function of indirectly illuminating the vehicle interior is not impaired.

The sub-ceiling at the front end of the cabin is provided at a predetermined distance below the main ceiling in substantially the same manner as the sub-ceiling at the rear end of the cabin, extends toward the center of the cabin, and has a peripheral edge formed with the main ceiling. It is formed upright so as to leave a predetermined distance. The sub-ceilings may be provided at both the front end and the rear end of the passenger compartment. Further, in the above embodiment, both ends of the light transmitting member are screwed to the sub ceiling via the bracket, but the invention is not limited thereto, and the light transmitting member may be screwed to the main ceiling via the bracket. In this case, the bracket is fixed to the main ceiling, and both ends of the light transmitting member are screwed to the bracket. Further, in the above embodiment, a lens formed of a transparent acrylic resin is used as the light transmitting member, but another member may be used as long as it can transmit light.
