Abstract:
1. A roller unit for forming a roller-type conveyor device in which rollers are arranged continuously on a conveyor frame, comprising: a rotating body that has a cylindrical part rotatably supported about a predetermined axis and is rotationally driven, the axis extending in an axial direction; a roller having an outer peripheral surface and two side surfaces, the roller being rotatably supported about the axis by an outer periphery of the cylindrical part to carry an object being conveyed on the outer peripheral surface of the roller, the side surfaces being at opposite ends of the roller in the axial direction; a pair of thrust plates that are arranged so as to be capable of pressing both side surfaces of the roller in the axial direction while holding the roller therebetween, and so as to rotate integrally with the cylindrical part; and a pressing force adjusting mechanism that is arranged inside the cylindrical part to adjust a pressing force with which the pair of thrust plates press the roller while holding the roller therebetween.
