To reduce the cost of a conveyor device and improve reliability of the conveyor device by simplifying a mechanism for correcting meandering of a conveyor belt.

This device comprises: a starting end pulley arranged at a conveying starting end of a belt 4; an terminal end pulley 2 arranged at a conveying terminal end; a fulcrum point pulley 7 arranged on an inner face of an outward path of the belt 4; a driving pulley 3 arranged on an inner face of a returning path of the belt 4; a conveyor frame 8 rotatably pivoting the fulcrum point pulley 7 and the terminal end pulley 2; and a tilt mechanism 9 for swinging the conveyor frame 8 upward and downward around a center shaft of the fulcrum point pulley 7. A correction pulley 15 correcting meandering of the belt 4 is arranged at a position capable of deflecting and guiding the returning path of the belt 4 toward the driving pulley 3 within a total swing angle range of the conveyor frame 8, so that one correction pulley 15 can correct meandering of the belt 4 within a total swing angle range of the conveyor frame 8.
