PROBLEM TO BE SOLVED: To provide a magnetic wheel with a guiding characteristic capable of following a curved running way having a specified radius of curvature excellently by providing it with a permanent magnet and a yoke which is formed to have a curved attraction face for passing the magnetic flux generated by the permanent magnet. SOLUTION: This wheel 1 is constructed to move freely in the perpendicular direction while being attracted to an outer circumferential surface 5a of a ferromagnetic pipelike rail 5. A shaft fixing flange 8 is provided in the wheel 1 around a wheel 9 connected to a motor 10, and on the outer circumferential side of the flange 8 an insulative vibration absorbing member 7 and a non- magnetic conduction spacer 12 is arranged. The spacer 12 is arranged on both sides through a protruding part 4b of a center yoke formed of a ferromagnetic Fe alloy, and a left part thereof extends to one side surface of the wheel 1 so that it gives a current collecting function to side wheels 6, 6. A ring-shaped permanent magnets 11, 11 are arranged at a lower outer surface and sandwitchedly fixed. |
