  PROBLEM TO BE SOLVED: To improve the transmissivity of rotational torque by making the repulsion force and attraction force by magnetism act well.SOLUTION: In a transport device 1, rotating bodies 61, 62 formed in a conical trapezoid are coaxially arranged respectively on the outside circumferences of a drive shaft 20 and driven ones 30. N poles and S poles are magnetized alternately and at equal intervals on the inclined surfaces 63a, 64a of the rotating bodies 61, 62. The N poles and S poles of the rotating bodies 61, 62 are arranged radially from the shaft center. The N poles and S poles are arranged with the same intervals on the rotating bodies 61 provided on the drive shaft 20 and the rotating bodies 62 provided on the driven shafts 30. The inclined surfaces 63a of the rotating bodies 61 and those 64a of the rotating bodies 62 are arranged close to each other in a non-contact state. The magnetized rotating bodies 61 on the drive shaft are rotated and driven by a drive mechanism 40. When the rotating bodies on the driven shafts 30 are rotated by the magnetic action of the rotating bodies 61, rollers 10 fixed to the driven shafts 30 are rotated and an object P to be transported is carried.COPYRIGHT: (C)2007,JPO&INPIT
