Abstract: A magnet-type transportation system of a car-side primary type includes a rail of a magnetic material, fixedly laid down along a traveling track, and a power car capable of self-movement by a plurality of wheels adapted to roll over the traveling track. The power car includes a plurality of magnet belt conveyor units, each having a magnet belt extended in an endless manner around a driving wheel and a driven wheel. The power car also includes a power unit and a power transfer/transmission mechanism for driving each conveyor unit. The power car is adapted so that the magnet belts mounted thereon are magnetically attracted to the rail.
