When a step is formed at the outer end of the joint s1 by stacking the above, the air conditioner-side packing 150 that supports the device 160 side across the step is placed, and the device is added to the vicinity of the step from the device. The load is unevenly applied to the roof side, and the flange portion g1 of the frame-shaped member 120 and the peripheral edge a1 of the roof opening portion
The hot melt 130 that seals and tends to receive the load in an unstable state, and the peeling of the hot melt 130 proceeds over time, resulting in a decrease in the adhesion of the air conditioner side packing 150 to the roof 100. There is a possibility. Further, due to the step difference generated by the flange portion g1 of the frame-shaped member 120 and the hot melt 130, there is a possibility that the sealability may be impaired due to variations in the seal area of the air conditioner-side packing 150.

できる。According to a first aspect of the present invention, an opening is formed in a roof of a vehicle so as to connect an upper region of the roof and a vehicle interior, and an upward flange is formed to project at a peripheral edge of the opening. In the vehicle body structure, the upward flange is formed at the introduction portion of the duct inserted from the vehicle interior into the opening portion, and the flange portion extending from the lower end of the introduction portion is integrally joined to the lower surface of the opening peripheral edge, It is characterized in that a sealing material is applied to the joint portion. Thus, the groove formed between the peripheral edge of the opening of the roof and the wall surface of the upward flange is filled with the sealing material, and the sealing material flows toward the bottom of the groove by its own weight and is filled in the joint portion. The sealing material stays in the same portion, and the sealing property can be stably obtained. Moreover, the coating operation can be easily and reliably performed from the upper side of the peripheral edge of the opening.

この場合も、請求項１と同様の作用効果が得られる。According to a second aspect of the present invention, in the vehicle body structure according to the first aspect, the opening communicates the device mounted on the roof and the vehicle interior. In this case, since the duct side flange is integrally joined to the lower surface of the opening peripheral edge of the roof,
Since the step is removed from the upper surface of the periphery of the opening of the roof, the device side can be stably placed on the roof via its supporting member, for example, the air conditioner side packing, and the sealing area of the air conditioner side packing can be reduced. Variations are eliminated, and the sealability at the same part can be secured. Preferably, the device may be mounted on the roof via a frame-shaped packing member that surrounds the opening. In this case, the device is placed on the peripheral edge of the opening of the roof through the frame-shaped packing member, but since the step is removed from the upper surface of the peripheral edge of the opening, the sealing property of the frame-shaped packing member is improved, and The sealability does not vary due to changes in the load applied to the upper surface of the peripheral edge of the opening, and the sealability can be stably secured. Preferably, the device mounted on the roof may be an air conditioner or a CNG device,
Also in this case, the same effect as that of the first aspect can be obtained.

The lower surface of the roof panel 201 can be evenly contacted with good adhesion, and rainwater or the like flowing on the roof panel 201 side can be reliably sealed by the air conditioner side packing 23 and can be prevented from entering the suction opening 18 of the roof panel 201. Further, as in the conventional example shown in FIG.
Since 1 is located on the upper surface of the peripheral edge a of the opening, a step is generated above the joint, the hot melt 130 is laid across the step, and the air conditioner-side packing 150 is sealed as in the case where it is placed there. It is possible to eliminate that the area varies, the sealability of the air conditioner-side packing 150 deteriorates, and the sealability of the joint becomes unstable.
