Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a sliding roof structure for a vehicle.

(Prior Art) For example, an external sliding roof structure is known as one of the sliding roof structures for vehicles. The external sliding roof structure includes an opening formed in the vehicle body, an opening/closing body that can freely open and close the opening, and a guide that guides the opening/closing movement of the opening/closing body, and the opening/closing body is moved above the roof through the guide. It slides to open the opening.

(Problems to be solved by the invention) However, in such a sliding roof structure,
For example, as schematically shown in FIGS. 5 and 6, if the guides 81 and 82 are provided only on the vehicle body side, the opening amount of the opening/closing body 83 will be the same as that between the rear stay 84 of the opening/closing body 83 and the fixed roof 85. Because of this restriction, the sliding roof structure cannot fully demonstrate its original functions of ventilation and lighting. Also, the seventh
For example, as shown schematically in FIG.
If the guide 91 is provided on the opening/closing body side, as in the sliding roof described in No. 57516, or the guide 92 is simply provided on the vehicle body side without being related to each other, the longitudinal stroke of the opening/closing body 93 will be the same as the guides 91, 9.
Therefore, in order to ensure a large length in front and back of the opening when the opening/closing body is opened, the guide 91 provided on the opening/closing body 93 needs to have a length that spans approximately the entire length of the opening/closing body. As a result, the weight on the opening/closing body 93 side increases, and in the open state where the opening/closing body is slid above the roof (Fig. 8), the rear part of the opening/closing body 93 vibrates due to vibrations during driving and becomes unstable. It becomes difficult to support and the opening/closing body 93
Due to the large weight of the vehicle, there is a problem in that the mechanism on the vehicle body side that supports it cannot be made lightweight and simple in structure.

The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to ensure a large longitudinal stroke of the opening/closing body and to increase the length of the opening longitudinally when the opening/closing body is opened. Furthermore, it is an object of the present invention to provide a sliding roof structure for a vehicle that can reduce the weight of an opening/closing body and a support mechanism for the opening/closing body.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes an opening formed in a vehicle body, an opening/closing body that can freely open and close the opening, and a closing body side guide rail provided on the opening/closing body side. , a vehicle body side guide rail provided on the vehicle body side, front and rear supports that support front and rear parts of the opening and closing body that are spaced apart from each other, and a tilt up mechanism that tilts up a rear part of the opening and closing body, and the front support. The lower end of the body is slidably engaged with the vehicle body side guide rail, and the rear support body is formed to extend in the longitudinal direction of the vehicle, and the front part of the rear support body is connected to the vehicle body side guide rail, The rear parts are slidably engaged with the opening/closing body side guide rails, and the opening/closing body is guided rearward via the vehicle body side guide rail and the front and rear supports with the rear part tilted up to open the opening. A sliding roof structure for a vehicle,
The opening/closing body side guide rail is formed to have a length from a location where the rear end of the rear support of the opening/closing body is located to a rear end of the opening/closing body when the opening is fully opened.
