ABSTRACT:
A conveyor device is formed with roller units arranged continuously on conveyor frames (10, 10′). Each of the roller units includes a rotating body (110) having a cylindrical part (111) rotatably supported around a predetermined axis (A) and being rotationally driven, a roller (120) rotatably supported by an outer periphery of the cylindrical part to carry an object being conveyed on the outer peripheral surface thereof, a pair of thrust plates (140, 150) arranged so as to be capable of pressing both side surfaces of the roller while holding the roller therebetween and rotating integrally with the cylindrical part; and a pressing force adjusting mechanism (160, 170, 180, 190) arranged inside the cylindrical part to adjust a pressing force with which the paired thrust plates press the roller while holding the roller therebetween.
