Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile sun roof structure.

[0002]

2. Description of the Related Art In many automobiles, a roof panel is provided with a roof opening, and the roof opening is opened and closed by a movable roof. The following roof openings are formed in the roof panel. That is, there is a pair of left and right roof openings in which the front and rear sides and the inner end side in the vehicle width direction are closed, while the front portion of the roof panel is opened outward in the vehicle width direction, respectively. See Kaihei 3-10933).

Such a roof opening is also called a T-bar roof, and since the outer end side in the vehicle width direction of the roof opening is opened, a feeling of release close to that of an opener can be obtained. .. The front edge portion of the pair of left and right roof openings is constituted by the front header, the rear edge portion thereof is constituted by the front edge portion of the rear portion of the roof panel, and the vehicle width direction inner end side edge is constituted by the front header. It is composed of a central connecting portion that connects the vehicle width direction intermediate portion with the roof panel rear portion.

The pair of left and right roof openings as described above are often opened and closed by using detachable roofs which are independently configured on the left and right sides. It is also performed to open and close the pair of left and right roof openings by moving one movable roof having a covering size in the front-rear direction.

In order to open and close such a pair of left and right roof openings with one large movable roof, it is necessary to smoothly guide the movable roof in the front-rear direction.
It has also been proposed to fix guide rails on the left and right end portions of the rear panel of the panel and to slide and guide the movable roof in the front-rear direction by the pair of left and right guide rails.

[0006]

By the way, when the movable roof is of the electric type, it is desired that the motor as a drive source is arranged on the front upper surface of the rear portion of the roof panel. In this case, since the motor is located behind the movable roof in the closed position, the motor is exposed to the outside as it is.

Therefore, it is an object of the present invention to presume that a pair of left and right roof openings are simultaneously opened and closed by one movable roof, and a motor is provided on the front upper surface of the rear portion of the roof panel. It is an object of the present invention to provide a sunroof structure for an automobile in which the appearance from the outside can be improved even when the vehicle is arranged.

In order to achieve the above object, the present invention has the following structure. That is, a pair of left and right roof openings are formed in the front portion of the roof panel in the vehicle width direction outside, and the front and the rear are closed to form a pair of left and right roof openings. The pair of left and right roof openings are opened and closed by a movable roof having a height,
In a sun roof structure of an automobile, a pair of left and right guide rails for slidingly guiding the movable roof in the front-rear direction are fixed on both left and right ends of a rear portion of the roof panel,
A motor for opening and closing the movable roof is mounted on the rear portion of the roof panel, and the motor is moved upward by a cover panel extending between the pair of left and right guide rails. It is covered from the inside.

[0009]

With this structure, the mode can be improved.
Since the tar is covered by the cover panel from above and cannot be seen from the outside, it is preferable for improving the appearance.

Further, the cover panel has a large shape extending between the pair of left and right guide rails, that is, when it is viewed from the outside, it is substantially shaped to form the rear portion of the roof panel. It will be fine in terms of appearance as a whole. Further, since the cover panel is located higher than the roof panel, it is possible to make the cover panel and the movable roof in the closed position substantially flush with each other, that is, the movable roof. The height can be increased, which is also preferable in terms of ensuring head clearance.
