<p>The purpose of the present invention is to improve the accuracy and strength of a threaded section consisting of a resin, the threaded section supporting a winding shaft so that the winding shaft moves in the axial direction thereof. A window shade device for a vehicle is provided with a window shade, a winding shaft, a threaded support shaft which is an example of one of a pair of support shafts, and a pressing-side support shaft. A threaded hole is formed in at least one end of the winding shaft. The threaded support shaft consists of a resin, and a threaded section which engages with the threaded hole and a center hole which extends along the axis of the threaded section are formed in the threaded support shaft. A reinforcement shaft is inserted through the center hole. A pressing mechanism which presses the winding shaft in the winding direction is provided at at least one end of the winding shaft.</p> |
