PROBLEM TO BE SOLVED: To reduce a cost by arranging a guide rail, a timing belt, a driving timing pulley and a carrier plate in a prescribed state. SOLUTION: The end part of a timing belt 2 is fixed to the lengthwise directional both end parts of a lifting guide rail 1. Next, a carrier plate 6 on which a window panel is installed is vertically slidably installed on the rail 1, and after fixing the driving part composed of a rotary drum 8 rotated at a reduced speed by a motor 7 and a timing pulley 9 coaxially integrally arranged on the drum 8, the belt 2 and the pulley 9 are meshed with each other. Next, the belt 2 and the pulley 9 are arranged between a pair of pulley 3 to secure a movement of the carrier plate 6. Therefore, looseness of the timing belt 2 can be easily eliminated by adjusting a position when installing the driving part on the carrier plate 6, and since the timing belt 2 can be largely secured on a length error, a length adjustment can be obviated, and the number of bolts when incorporated into a door panel can be reduced. |
