To satisfy the requirements that a light-weight semitransparent or mesh-inclusive thin raw material is preferable for use in a blade 6 and a large folding fan-like member which is attached to a window glass of an automobile and forms a sunshade is necessary because this sunshade is used as the sunshade attached to the automobile.

When opening and closing a folding fan, force for pushing and widening other framework acts on the blade 6, and, on the contrary, force for contracting from a hollow shaft 1 acts to take a method in which force required for the necessity is entrusted to a guide panel 5. Consequently, force is not applied to the blade 6, and the raw material which is as thin as possible, is soft, and has no stiffness can be used in the blade 6. The guide panel 5 is made thick and strong to realize the larger folding fan-like member.
