ABSTRACT:
To provide a conveyor belt which is light in weight, easy to clean, free from rust, and easy to manufacture, a plastic conveyor belt is formed in an endless shape, by sequentially coupling belt constituent units, each of which comprises a cranked connection piece formed by joining horizontal portions of two plates each having an L-shaped cross section such that vertical portions of the two plates are not located on the same side, a rod which is connected integrally with an inner vertical portion of the connection piece, and has a core-sheath structure consisting of a metal core portion and a plastic sheath portion, a connection shaft provided on one portion of the connection piece, and a connection piece having a connection hole formed in a portion of the connection piece where the connection shaft is not provided. The belt constituent units are coupled with each other by bringing the vertical portion of the connection piece into contact with a cranked stepped portion of another connection piece, and inserting the connection shaft into the connection hole such that the connection shaft is freely rotatable. The present invention also provides a conveyor apparatus comprising this conveyor belt and a sprocket.
