[0004]

In the case of a steel-made roof panel, the heat generated by the room lamp can be diffused by the steel-made roof panel itself, so that the heat of the room lamp affects the roof panel. It can hardly be given. However, in the case of the resin roof panel, since the thermal conductivity is small and the linear expansion coefficient is large, if the resin roof panel is locally heated by the heat of the room lamp, there is a possibility that local deformation or residual deformation may occur. For this reason, in the case of a resin roof panel, it is necessary to suppress the local deformation by thickening so as not to impair the appearance quality,
There was a limit to weight reduction while using a resin roof panel.

It is mounted on the roof frame main body 1 composed of the bow roof unit 13 and is fixed with an adhesive or a bolt and nut (not shown).

The structure around the lamp mounting portion 23 is shown in FIG.
3A showing a cross section of a portion IIIa of FIG. 3A, and a cross section taken along the line IVa-IVa of FIG.
(A). Also, the lamp mounting part 2 of FIG.
5 is a cross-sectional view of a portion indicated by Va in FIG.
(A). Further, a cross section taken along the line VIa-VIa in FIG. 1 is as shown in FIG.

First, as shown in FIGS. 3A and 4A,
The lamp mounting portion 23 has a room lamp 27 as a lamp.
Is mounted close to the resin roof. The room lamp 27 has a lamp portion 27a as a light source attached to a housing 27b, and a lens 27c provided on a lower surface of the housing 27b. The bow roof part 1
3, a lamp mounting hole 29 is provided in the mounting portion 23, and the housing portion 27b of the room lamp 27 is fixed to the lamp mounting hole 29.

The lamp mounting hole 29 is provided with a lamp blocking portion 31 for covering the resin roof panel side. The lamp cutoff section 31 is formed integrally with the bow roof section 13 and is formed of a casting of a light metal such as an aluminum alloy or a magnesium alloy made of the same material as the bow roof section 13.

The lamp blocking section 31 comprises a top plate 31a and front and rear left and right walls 31b, 31c, 31d and 31e. The top plate 31 a is
The front and rear left and right walls 31b, 31c, 31d and 31e are positioned to cover the upper side of the room lamp 27 and cover the front and rear and left and right of the room lamp 27. 33 is a roof trim.

FIG. 3 (b) shows a cross section at the same place as that of FIG. 3 (a), and shows a structure in which the lamp cutoff section 31 is not provided in the lamp mounting hole 29.
FIG. 3B shows a cross section taken along the line IVb-IVb.
FIG. 4 (b) corresponding to FIG. 4 (a).

The lamp 27 of the room lamp 27
When the lamp a is turned on, heat is generated, and when the lamp blocking portion 31 is not provided in the lamp mounting hole 29 as shown in FIGS. 3B and 4B, the resin roof panel 3 is locally heated by the heat. Local deformation and residual deformation 3a may occur to impair the aesthetic appearance of the outer surface, particularly when both are close to each other. Therefore, such local deformation 3
It is necessary to make the resin roof panel 3 thick so as not to cause a and the like.

On the other hand, as shown in FIGS. 3 (a) and 4 (a),
When the lamp cutoff section 31 is provided, and the lamp cutoff section 31 and the bow roof section 13 are made of light metal having good thermal conductivity, the heat generated by the lamp section 27a is first cut off by the top plate 31a of the lamp cutoff section 31, and the resin is removed. Direct transmission to the roof panel 3 side can be suppressed.

Further, the heat conducted to the top plate 31a of the lamp cutoff unit 31 is conducted from the top plate 31a to the bow roof unit 13 via the front and rear left and right walls 31b, 31c, 31d and 31e with good thermal conductivity. Furthermore, it is diffused as a whole to the left and right side roof rail portions 5 and 7.

Due to such diffusion of heat, the resin roof panel 3 expands as a whole as shown at 3b, and local deformation and residual deformation can be prevented. Therefore, even if the resin roof panel 3 is not made thick, local deformation and residual deformation of the resin roof panel 3 are prevented, and the appearance of the outer surface is not spoiled.

As shown in FIG. 5A, a map lamp 37 is mounted on the lamp mounting portion 25 of the front roof rail 9 in a lamp mounting hole 35 as a lamp. In the lamp mounting portion 25, the lamp mounting portion 2 is also used.

The lamp cut-off portion 39 is formed integrally with the front roof rail portion 9 and is formed integrally with a light metal such as an aluminum alloy or a magnesium alloy which is the same material as the front roof rail portion 9 and has a high thermal conductivity.

The map lamp 37 has a ramp portion 37a.
And a housing portion 37b, a lens portion 37c, and the like. Reference numeral 41 denotes a front window panel.

FIG. 5 (b) shows a structure in which the lamp cutoff portion 39 is not provided in the lamp mounting hole 9 which is open in the same cross section as FIG. 5 (a). Also in this portion, when the lamp portion 37a of the map lamp 37 is turned on, if the lamp cutoff portion 39 is not provided, there is a possibility that local deformation 3c or the like of the resin roof panel 3 may occur due to heat generation. In order to prevent the deformation 3c, the resin roof panel 3 needs to be formed thick.

On the other hand, when the lamp cut-off portion 39 is provided as shown in FIG. 5A, heat is generated by the lamp cut-off portion 39 as in the description of FIGS. 3A and 4A. The resin roof panel 3 is shielded and diffused entirely from the lamp blocking part 39 to the bow roof part 13 side, so that the deformation of the resin roof panel 3 can also be the entire deformation 3d.

Accordingly, the thermal stress of the resin roof panel 3 is small, no residual deformation occurs, and the appearance of the outer surface is not spoiled. Further, since the lamp blocking portion 39 is formed integrally with the front roof rail portion 9, manufacture and assembly are extremely easy.

As shown in FIG. 6A, a duct 43 for a vehicle air conditioner is provided in the side roof rail 5 portion. The interior of the duct 43 is covered with a garnish 45, and a duct blocking part 47 is provided above the duct 43.

The outer portion 5b of the roof side rail 5 is also formed of a light metal casting material having good thermal conductivity, such as an aluminum alloy or a magnesium alloy.

FIG. 6B shows a cross section at the same location as FIG. 6A, and shows a structure in which the duct blocking portion 47 is not provided. Therefore, as shown in FIG. 6B, when the vehicle is parked under hot weather in summer, when the cooling air of the air conditioner is drawn from the duct 43 to the vehicle interior side, the duct 43 and the resin roof panel 3 are The resin roof panel 3 may be locally deformed 3e due to a large temperature difference therebetween, and the resin roof panel 3 needs to be formed thick to prevent the local deformation 3e.

On the other hand, when the duct shut-off portion 47 is provided as shown in FIG. 6 (a), the low temperature of the duct 43 is shut off from the resin roof panel 3 and the duct shut-off having a good thermal conductivity. The portion 47 is transmitted to the inner portion 5a and the outer portion 5b of the roof side rail 5 and is diffused entirely, so that the resin roof panel 3 is entirely deformed like 3f, and the thermal stress is small. It does not cause residual deformation and does not impair the appearance of the outer surface.

In the example shown in FIG. 6, the duct 43 of the vehicle air conditioner is attached to the side roof rail 5, but the duct is extended to the front roof rail 9, the rear roof rail 11, the bow roof rail 13, and the like. The same can be applied to the case of setting.

9a and the front and rear left and right walls 49b, 49c, 49d, 49e, and due to its high thermal conductivity, are immediately transmitted and diffused to the flange 49g side. Also, heat is conducted from the fixed wall 49f to the bow roof portion 13 having the same high thermal conductivity, and the heat is diffused as a whole.

Therefore, in the present embodiment, substantially the same functions and effects as those of the first embodiment can be obtained. Further, in the present embodiment, since the lamp blocking portion 49 is formed of a material having a higher thermal conductivity than the bow roof portion 13,
