It is disclosed that the rail is simply slidably fitted to the rail through the shoe.

[Problems to be solved by the invention] However, in such a conventional technique, since the branch line of the curtain member is simply guided by the rail, it is difficult to sufficiently stretch the curtain member even if the curtain member is fully deployed. However, there is a problem that not only is it unpleasant due to the occurrence of noise, but also it is easy to rattle and an abnormal noise is generated to make the user uncomfortable.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a sunshade device which does not rattle during use and does not cause discomfort.

[Means for Solving the Problems] The gist of the present invention for achieving such an object is to: 1 In a sunshade device in which a foldable shade cloth is used to open and close an opening, A rail having a guide groove facing each other is provided, and the guided element is movably fitted in the guide groove of each rail, and in each rail, the guided element is sequentially connected by a link member to form a chain. A sunshade device in which an elastic body for preventing play is attached to at least one of adjacent link members when the chain is folded.

2 In a sunshade device in which the opening is opened and closed with a foldable shade cloth, rails having guide grooves facing each other are arranged on both side edges of the opening, and the guided element can be moved in the guide groove of each rail. In each rail, a guided member is sequentially connected by link members to form a chain, and a storage portion for accommodating the folded link member is provided at the end of each rail, and the guided member of the link member is The sunshade device is characterized in that an elastic body for preventing backlash that is received from the side is attached to a side wall of the housing portion.

[Operation] When the link member, which has been folded in the housing to close the opening, is extended and moved into the rail, the guided element moves in the guide groove of the rail, and the shade cloth is deployed.

When the chain extends completely and the shade cloth expands to the full opening,
The expanded link member is restrained by the guide groove of the rail, and the shade cloth is stretched.

On the contrary, when opening the opening, the chain is moved in the closing direction.
The link members are folded and superposed one after another in the storage part, and finally the opening is fully opened.

When the link member is folded and stored in the storage portion, at least one of the elastic members for preventing backlash is interposed between the adjacent link members, so rattling is suppressed and abnormal noise is generated. There is no.

Further, when the link member swings in the lateral direction, the elastic body for rattling mounted on the side wall of the storage section receives the guided element, so rattling is similarly suppressed, and abnormal noise is not generated. Absent.
