PROBLEM TO BE SOLVED: To provide a roller type conveyer having a non-contact type power transmission system using magnetic force, capable of increasing a roller effective width if the conveyor width is the same, and preventing dirt, rust and the like in a driven magnetic wheel. SOLUTION: Conveyance rollers B in which a permanent magnet ring 3 is engaged and fixed at the inside of a cylindrical body 2 which is constructed by a non-magnetic element, bearings 4 are fitted and fixed at the inside on both sides in an axial direction of the cylindrical body, and a spindle 5 is engaged over the bearings on both the sides so that the cylindrical body may be rotated freely are disposed at a frame A at a prescribed interval in parallel to constitute a conveyance surface, and a driving magnetic wheel 6 at a position mating with the permanent magnet of the conveyance rollers of the conveyance surface is made to cross an outer periphery surface of the roller in a non-contact state to be approximated and disposed so as to be rotated freely, thus rotating the conveyance roller by rotating the driving magnetic wheel directly or indirectly.
