1. A transport conveyor comprising:
a first pulley that rotates about a first rotating shaft;
a second pulley that rotates about a second rotating shaft;
a pair of frames that support the first rotating shaft and the second rotating shaft; and
a conveyor belt wound around, and extending between, the first pulley and the second pulley, wherein
at least one frame of the pair of frames is configured as an offset frame including offset supports, the offset supports supporting the first rotating shaft and the second rotating shaft at respective positions that are located inward of both ends of the conveyor belt in a width direction thereof,
the pair of frames include:
a pair of frame bodies including respective outer surfaces that are orthogonal to the first rotating shaft and the second rotating shaft; and
a pair of tension adjusters that are connected to the pair of frame bodies and that adjust tension of the conveyor belt by adjusting a distance between the first pulley and the second pulley,
the pair of tension adjusters are provided outward of the respective outer surfaces of the pair of frame bodies in the width direction of the conveyor belt, and
of the pair of tension adjusters, the tension adjuster provided on the offset frame side is positioned between one of the offset supports and an end of the offset frame side of the conveyor belt in the width direction thereof.
