ABSTRACT:
There are provided linear section moving chain conveyors for moving carrier trucks on linear sections of a guide rail, curvilinear section moving chain conveyors for moving the carrier trucks on curvilinear sections of a guide rail, and conveyance interval variable portions for moving the carrier trucks on borders between the linear sections and the curvilinear sections while gradually varying the interval between the carrier trucks. When the carrier trucks are moved from a linear section to the following curvilinear section, spiral screws of the conveyance interval variable portions gradually widen the intervals between the carrier trucks, and when the carrier trucks are moved from a curvilinear section to the following linear section, the screws gradually narrow the intervals between the carrier trucks.
