Description

  The present invention relates to a windable sunshade device that blocks a daylighting portion of a sunroof, and more particularly to a sunshade device for a vehicle such as an automobile that can store a sunshade member (hereinafter referred to as a shade) small.

  Some vehicles equipped with a sunroof for daylighting are equipped with a sunshade device as a sunshade for blocking direct sunlight. This sunshade device has a problem that when the shade is pulled out under the daylighting part of the sunroof, the shade hangs down, and the overhead space of the passenger, particularly the passenger, becomes narrow. Therefore, a sunshade device has been proposed in which a leaf spring curved upward is attached to the shade (see, for example, Patent Document 1). In this sunshade device, a plurality of leaf springs are attached to the shade at predetermined intervals in parallel to the winding shaft. The shade is bent upward by this leaf spring.

Further, a sunshade device has been proposed in which a winding shaft that winds up a shade is curved upward, and a curved member that is curved upward is provided in a shade drawer portion that faces the winding shaft (see, for example, Patent Document 2). ). In this sunshade device, a member that is curved before and after the shade is provided, and the shade is curved upward by always pulling the shade by the winding shaft.
