Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a guide support portion of a sunroof that slidably guides and supports a sunroof in an automobile having a sunroof.

(Prior Art) A vehicle with a sunroof that can open and close a roof opening by a sunroof that can slide forward and backward is disclosed in Japanese Patent Laid-Open No. 63-24272.
As widely known in Japanese Patent Publication No. 0, etc., front roof rails are formed by front rails arranged in the front-rear direction on both sides of the roof opening, and at the rear of the roof opening of the roof. The rear rail constitutes a rear roof rail, and these roof rails guide and support the sunroof so that the sunroof can be slid back and forth via the respective support arms.

(Problems to be solved by the invention) However, in the above-mentioned conventional example, the roof rails on the front side are individually attached to the roof portion, and the assembly of the constituent members on the front side is not achieved, so that the work efficiency is improved. There is a problem that improvement is difficult.

The factor that hinders the assembly is that it is difficult to assemble the assembly in which the left and right roof rails are assembled into the roof opening by accurately determining the distance between the roof rail and both sides of the roof opening. This is also because it is difficult to use a housing member of the assembly that has high rigidity and little bending in order to avoid weight increase.

If the distance between the two is not accurate, the distance between one side of the sunroof and one side of the roof located behind the opening is insufficient when sliding in a lifted state, and there is the problem of interference. Also, in order to avoid this situation, there is a waste of having to set a large lift-up amount. Further, there is a problem that the pressure contact force with respect to the weather strip on both sides of the sunroof varies when the roof opening is closed.

The present invention has been made in view of the above-mentioned conventional example, and an object thereof is to provide a structure of a guide support portion of a sunroof capable of solving the above-mentioned problems and realizing an assembly of a roof rail.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a roof opening provided in a vehicle body roof, and sunroofs covering the roof opening are provided along both side edges of the roof opening. Guided by the roof rail, the sunroof is movable between a roof opening lid closing position and a vehicle body roof rear lid closing position behind it, and moves from the roof opening lid closing position to the vehicle body roof rear lid closing position. When the sunroof is configured to be lifted up at this time, the sunroof is formed in a shape in which both side portions are bent so as to hang down so that the cross-sectional shape thereof follows the cross-sectional shape of the rear portion of the vehicle body roof, and the roof rail is a frame-shaped housing The assembly body assembled on both sides of the roof assembly is assembled on the roof opening, and the positioning portions abutting on both side surfaces of the assembly body are positioned on the roof opening. It is characterized in that it is provided on both sides of the mouth.

(Operation) In the above configuration, the positioning portions provided on both sides of the roof opening are brought into contact with both side surfaces of the assembly,
Since the positioning of the roof rail with respect to the side portion can be performed directly on the basis of the roof, the mounting position of the sun roof guided and supported by the assembly can be accurately set.

As a result, even if the lift-up amount of the sunroof is suppressed to the necessary minimum, it is possible to avoid the interference between both sides of the sunroof and the both sides of the rear part of the vehicle body roof located behind the opening when sliding in the lifted-up state. With
When the roof opening is closed, the pressure contact force to the weather strips on both sides of the sunroof can be made uniform so that the operation of the sunroof can be performed lightly.

Even if the guide support portion of the sunroof is assembled, the mounting position of the sunroof with respect to the roof portion can be accurately set as described above. Therefore, the effect of assembly, that is, when the guide support portion is assembled to the roof portion, can be obtained. The effect of improving workability can be obtained.
