DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle roof structure.

[0002]

2. Description of the Related Art In vehicles such as passenger cars and hood trucks, a roof structure (roof structure) called a roof structure with drip channels is usually employed.

The roof structure with a drip channel is as shown in FIGS.

That is, in the door opening 2 in the vehicle body 1 shown in FIG. 6, a drip channel 4 is attached to a side outer member 3 forming a side surface of a vehicle compartment (spot welding portion 5), as shown in FIG. A roof member 6 forming a roof is placed on the side outer member 3 from directly above, and the roof member 6 is fixed to the drip channel 4 (spot welding portion 7).

In the pillar portion 8 shown in FIG. 6, as shown in FIGS. 8 and 9, the roof member 6 is put on the side outer member 3 from directly above and the wrap portion 9 with the side outer member 3 is formed. The roof member 6 is joined by brazing or arc brazing.

In the drawings, reference numeral 10 denotes a side inner member.

According to such a configuration, since the roof member 6 and the side outer member 3 are vertically divided by the pillar portion 8, the roof member 6 is structurally placed on the side outer member 3.
There is no hindrance when covering the head from directly above.

However, the roof member 6 and the side outer member 3 overlap at the side edge of the roof to form a double structure, leading to an increase in weight and cost, while the drip channel 4 is required to mount the roof member 6. And troublesome work such as brazing and arc brazing are required.

Therefore, in recent years, a roof structure called a drip channelless roof structure which eliminates the double structure at the side edge portion of the roof and eliminates the need for the drip channel 4 has been adopted.

[0010] The drip channelless roof structure comprises:
As shown in FIGS. 10 to 14, the boundary 13 between the roof member 11 and the side outer member 12 is moved toward the center of the roof 14, and one of the groove side wall 15 and the groove bottom is formed at the boundary 13 on the roof member 11 side. 16 and the other groove side wall portion 17 and the groove bottom portion 18 are formed at the boundary portion 13 on the side outer member 12 side, so that the groove bottom portion 16 of the roof member 11 is located above the groove bottom portion 18 of the side outer member 12. To form a groove 20 (extending in the full length of the roof portion in this example) extending substantially in the front-rear direction 19 of the vehicle.
6 and 18 are spot-welded, and the groove 20 is filled with a rubber or resin molding (not shown) to hide the boundary portion 13.

As described above, by adopting the drip channelless roof structure, the double structure at the side edge portion of the roof can be eliminated, and the drip channel 4 can be eliminated, so that labor such as brazing and arc brazing can be reduced. Work can be eliminated.

However, the drip channelless roof structure has the following problems.

That is, in a vehicle, a window glass (especially a window glass 21 which is substantially perpendicular to a rear portion of a bonnet truck) is usually attached to a front portion and a rear portion. FIG.
1, window glass 2 as shown in FIG. 13 and FIG.
1 to bend the inner bent portions 22 and 2 for fitting glass
3 and falling portions 24, 25 for supporting the glass must be formed, and the front ends of the roof member 11 and the side outer member 12 are also provided at the front ends of the roof member 11 and the side outer member 12.
Inner bent portion 2 for fitting a window glass as shown in FIG.
2 ', 23' and falling portions 24 ', 2 for supporting glass
5 'must be formed.

Since these are inevitably formed below the general surface forming portions 28, 29 and 28 ', 29' of the roof 14, the roof member 11 is intended to be mounted from directly above. In this case, as shown in FIG. 14, the hidden surface forming portion 26 particularly at the rear end of the roof member 11
There is a high possibility that the roof member 11 will not be able to be attached due to interference with the general surface forming portion 29 of the side outer member 12 arranged below (interference amount L).

The hidden surface forming portion 26 'at the front end of the roof member 11 also interferes with the general surface forming portion 29' of the side outer member 12 disposed therebelow. Since the interference amount L at the end is relatively small, the front end of the roof member 11 can be attached to and attached to the side outer member 12 by bending of the inner bent portion 22 ′.

Therefore, as shown in FIG. 15, the inner bent portion 22 and a part of the falling portion 24 in the hidden surface forming portion 26 of the roof member 11 do not interfere with the general surface forming portion 29 of the side outer member 12. The roof member 11 is mounted on the side outer member 12 from directly above.

[0017]

As described above, the inner bent portion 22 and a part of the falling portion 24 in the hidden surface forming portion 26 of the roof member 11 do not interfere with the general surface forming portion 29 of the side outer member 12. In the case of cutting, as shown in FIG. 15, a gap of dimension c is formed between the hidden surface forming portion 26 of the roof member 11 and the hidden surface forming portion 27 of the side outer member 12. It is necessary to fill the hole with the putty sealer 30 so that rainwater or the like does not enter, but it is difficult to attach such a putty sealer 30 and it cannot be said that it is sufficient from the viewpoint of reliability, and the appearance is deteriorated. Had disadvantages.

In view of such circumstances, the present invention allows the roof member to be positioned directly above the side outer member without creating a gap between the hidden surface forming portion of the roof member and the hidden surface forming portion of the side outer member. An object of the present invention is to provide a vehicle roof structure that can be put on and attached, can make it unnecessary to attach a putty sealer or the like, can surely prevent intrusion of rainwater or the like, and can avoid poor appearance.
