DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sun roof deflector structure having a rectifying body which can be displaced up and down at a front edge of an opening of a fixed roof which can be freely opened and closed by a slide panel.

[0002]

2. Description of the Related Art In a sunroof having an openable and closable opening in a fixed roof of an automobile, an arrangement for suppressing wind noise generated when the vehicle is running with the opening being opened and wind entrainment into a vehicle interior. Deflectors are known in which a fluid is provided at the leading edge of the opening. In this type of deflector, the rectifier body stored below the slide panel is displaced to an operating position in conjunction with the slide panel when the opening is opened, so that the rectifier body itself can be tilted up and down, or a tilt arm is provided. A configuration is adopted in which the rectifier can be moved up and down through the intermediary.

[0003]

However, as described above, in order to vertically displace the straightening body between the storage position below the slide panel and the operating position at the front edge of the opening, it is necessary to provide the straightening body in the fixed roof. It is convenient to support the rectifier body on the frame for supporting the slide panel. At this time, it is necessary to connect the rectifier body to the frame with sufficient strength so that vibration does not occur due to wind pressure at the operating position. is there. For this reason, it is difficult to simplify the mounting structure of the rectifier to the frame, and it has not been possible to sufficiently satisfy the demands for reducing the number of assembling steps and miniaturization.

[0004] The present invention has been devised to solve such problems of the prior art, and its main objects are as follows.
It is an object of the present invention to provide a deflector structure that is configured to be easily incorporated into a sunroof and to be reduced in size.

[0005]

In order to achieve the above object, according to the present invention, a deflector structure of a sunroof is provided with an insertion groove 9 for inserting a driving push-pull cable, and a slider provided on a slide panel. At the front ends of a pair of left and right side frame members 4 integrally formed with a guide groove 10 for sliding sliding and a side drainage groove 11 for discharging rainwater out of the vehicle. The rectifier 2
4 were integrally connected via a hinge part.

[0006] According to this, by attaching a shield in which a rectifier is integrally provided in advance to the frame, the rectifier is also incorporated into the frame at the same time. The number of steps for incorporating the fluid can be reduced, and the configuration can be simplified to reduce the size. In addition, since the shield is firmly connected to the frame in order to obtain the required effect of preventing flooding, the rectifier can be supported with sufficient strength.

In particular, it is preferable that the shield and the rectifier are integrally formed of a highly flexible synthetic resin material in a state where they are connected to each other via a thin portion 29 as a hinge portion. According to this, it is possible to reduce the weight and the manufacturing cost.

In the above-mentioned shield, since the left and right separate members are provided separately from each other, it is desirable that the rectifier is also a separate right and left member so as not to increase the number of manufacturing steps. Also,
The shield prevents water from penetrating into the insertion groove and the guide groove as described above. This is because the side frame member is formed by extrusion molding of an aluminum alloy material. When all of the drain grooves are open at the cut end face, rainwater from the front drain grooves of the front frame member flows into the guide grooves and the insertion grooves, or falls from the corners on the front edge side of the openings. An object of the present invention is to avoid malfunctions caused by water droplets entering the guide groove and the insertion groove from the upper surface.
