Abstract: An incident intensity L is categorized into a low illuminance range A1 for immediately moving a sun visor body toward a retracted position, a high illuminance range A2 for immediately moving the sun visor body in a target direction set based on an incident angle, and an intermediate illuminance range A3 set between the two regions A1 and A2. When the incident intensity is in the region A3 and after the target position is continuously set closer to the retracted position or the projected position than the present position for a predetermined time, the sun visor body moves toward the target position. That is, there is a range between an illuminance threshold L1 for immediately moving the sun visor body toward the retracted position and an illuminance threshold L2 for immediately moving the sun visor body in the target direction based on the incident angle.

Abstract: In a swinging apparatus (rotatively moving and swinging apparatus), a swing arm 51 positions a rotatively moving pedestal 45 and a cushion base 51. The swing arm 51 is swung around a driving shaft 60 to swing the cushion base 51, that is, to elevate or lower the cushion base 51 and to move it forward or backward. The cushion base 51 supports a seat portion 30. When the seat is in a forward position in which it is directed toward the front of the vehicle, the swing arm 55 diagonally connects the members 51 and 45 together (Z type). This prevents, in the forward position, the swing arm 55 from extending upward from the cushion base 51 or the rotatively moving pedestal 45 from extending laterally from the seat portion 30. Therefore, the size of the apparatus can be reduced across the width and height.
