ABSTRACT:
A vehicle door, wherein a drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires are laid are provided at upper and lower sides of a base panel. The glass plate is moved up and down by driving the wires, and the glass plate is prevented from moving in a vehicle inward direction when the door is closed. Wire fixing portions are prevented from being damaged by large upward and downward stroke movements of the glass plate Furthermore, the wires are prevented from slackening when the wires are driven and stopped by providing a supporting rod along a path of upward and downward movement of the glass plate, and a contact member which has no contact with the supporting rod. Trumpet-shaped guide portions are provided at hole edges of the wire fixing portions, and the V-shaped circumferential surfaces of a tensioner eliminates slack in the wires.
