PURPOSE: A belt conveyor is provided to improve the replacement workability of a central roller because the central roller rotates on a rotary shaft to prevent interference with a transfer belt. CONSTITUTION: A belt conveyor comprises a pair of fixed frame parts(10), coupling parts(20), rotation parts(30), a central roller part(40), and inclined roller parts(50). The fixed frame parts are arranged in the longitudinal direction of a transfer belt. The coupling parts are mounted on the fixed frame parts and are arranged to cross the transfer belt. The rotation parts are inserted into the coupling parts. The central roller part is mounted on the rotation parts and penetrates through the coupling parts so that the transfer belt can be supported. The inclined roller parts are mounted on the coupling parts and are arranged on both sides of the central roller part so that the transfer belt can be supported.
