ABSTRACT:
Left side panels and right side panel are produced in a left side panel production line and a right side panel production line, respectively By vertical lifters, each left side panel and each right side panel are lifted at the delivery stations and then transferred to runners at work transfer positions. The runner with the left side panel held thereon travels along a rail while the runner with the right side panel held thereon travels along a rail. Both runners are stopped at a standby position and then conveyed to a runner transfer position simultaneously. The runners with the left and right side panels held thereon, respectively, are loaded on the traverser and then conveyed to a drop lifter arranged above a main body assembly line. The left and right side panels are transferred to the drop lifter. The drop lifter then descends and feeds the left and right side panels simultaneously on opposite sides of a floor panel in the main body assembly line.
