[0004]

As described above, the sunshade 101 is supported by four supporting members 103 at the front and rear. In addition, a biasing force is applied in the vehicle width direction (arrow) by the pair of supporting legs 109 so that the mounting can be performed without rattling.
Since the mounting member 3 is provided at four positions on the front, rear, left and right sides, the mounting operation is very troublesome, and the supporting member 103 of the sunshade 101 has a shape that correctly responds to vertical movement caused by vibration or the like. In some cases, the material may be cracked due to fatigue of the material when used for a long period of time.

Accordingly, an object of the present invention is to provide a sunshade support device for a sunroof which is excellent in assemblability and can provide stable support for a long period of time.

[0006]

To achieve the above object, the present invention provides a sunroof having a sunshade slidable back and forth along guide rails provided on both sides of a roof opening. At the front and rear of the side and at least one intermediate position, a mounting portion is provided, and the front and rear mounting portions are provided with mounting holes that open in the vehicle width direction, while along the longitudinal direction of the guide rail,
A spring body made of a long wire rod having front and rear portions having at least two projecting parts extending forward and backward toward the guide rail side is disposed, and both ends of the spring body are bent toward the mounting part side, and one of the bent ends is bent. The spring terminal portion is inserted into and supported by the mounting hole of the front mounting portion, and the other spring terminal portion is inserted into and supported by the mounting hole of the rear mounting portion. Corresponding to the insertion direction of the spring terminal portion, the spring terminal portion is engaged and supported by the intermediate mounting portion so as to prevent the inward movement in the vehicle width direction or the outward movement in the vehicle width direction. The guide rail is slidably engaged in a guide groove formed along the longitudinal direction of the guide rail.

[0007]

According to this sunroof sunshade support device, only two spring bodies are required on the left and right, and one bent spring terminal is provided in the mounting hole of the front mounting portion, and the other spring terminal is provided in the mounting hole of the rear. , And can be easily mounted by engaging and supporting an intermediate mounting portion between the overhanging portions.

Further, the sunshade can be supported by engaging the projecting portion of the spring body with the guide groove of the guide rail. At this time, it is surely supported by the urging force of the overhanging portion, and a reasonable supporting state can be stably obtained over a long period of time even in the vertical direction, as a matter of course, in the vehicle width direction.
