Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunshade guiding device for a sunroof for an automobile, in which a sunshade for opening a window formed on a vehicle body roof is guided by left and right guide rails so as to be movable back and forth.

[0002]

2. Description of the Related Art A sunshade for an automobile is usually provided with a sunshade. When the sunshade is moved forward or backward, a window opening formed in a vehicle body roof is opened and sunlight is emitted into a passenger compartment. When it is introduced to the other side and moved to the other side, the window opening is closed to block the sunlight (Japanese Utility Model Laid-Open No. 58-25722).
