Abstract
A roller conveyor in which articles are supported by idler rollers carried by a main frame and conveyed as the idler rollers are driven into rotation. A plurality of first idler rollers are arranged in one of two side frames of the main frame. A plurality of second idler rollers capable of supporting articles in pair with the first idler rollers are arranged in the other side frame. Driving force for conveying articles is given to the first idler rollers only. The fact that first idler rollers and second idler rollers are separately arranged at opposite sides assures that the first and second idler rollers are of short and light construction.
