A window shade device includes a windup device that winds up a window shade to be drawn/housed, a guide and support mechanism that includes a guide rail including a guide path and a movable member configured to move along the guide rail, and an arm that is coupled to the window shade and is supported by the movable member so as to change its posture. A first gear is provided to the arm, and a second gear is provided to at least a part of the guide path. A deceleration gear mechanism configured to mesh with the first gear and the second gear decelerates and transfers the rotational movement upon meshing with the second gear as the rotational movement for causing the arm to change its posture upon meshing with the first gear.
