The winding shaft 14 </ b> A extends along the width direction of the screen 12. A base end portion of the screen 12 is fixed to the winding shaft 14 </ b> A from one end in the width direction of the screen 12 to the other end.

  The winding shaft 14A is rotatably supported by a base member 22 extending from one end in the width direction of the screen 12 to the other end via a bearing portion 26F of a bracket 26 described later. The base member 22 is supported at both ends in the axial direction by brackets 26 as an example of a support, and is supported at the center in the axial direction by the bracket 36. The specific configuration of the base member 22, the bracket 26, and the bracket 36 will be described later.

  Further, the winding shaft 14A is always urged toward one side around its own axis by an urging means such as a spiral coil spring (not shown), and an external force that opposes the urging force of the urging means does not act. In the limit, the screen 12 is wound around the outer periphery of the winding shaft 14A by the biasing force of the biasing means.

  A screen support member 16 as an example of a support member that supports the front end portion of the screen 12 is fixed to the front end portion of the screen 12. The screen support member 16 extends along the width direction of the screen 12, and supports the screen 12 from one end to the other end in the width direction of the screen 12.

  A pair of guide members 18 for guiding the screen support member 16 to a deployment position where the screen 12 is deployed are disposed on one end side and the other end side in the longitudinal direction of the winding mechanism 14. The guide member 18 is supported by the base member 22 via a guide member support portion 26G of the bracket 26, and extends linearly in the drawing direction of the screen 12 along the side end portion of the screen 12.
