PURPOSE:To prevent a load from being damaged in a locked-up state, by utilizing rotary magnets instead of gears and using the magnetic coupling of the magnets to transmit rotation to an output shaft without contact. CONSTITUTION:A rotor 2 and a rotary shaft 3 are attached to a stator 1. The driving force of the rotary shaft is transmitted to a load connecting shaft 9 through rotary members 4-7. N-poles and S-poles are alternately provided on the rotary members 4-7 in their circumferential direction so that the numbers of the magnetic poles of the rotary members are different from one another and the magnetic poles are located at almost equal intervals. As a result, the rotation of the rotor 2 is transmitted to an output shaft 9 while the rotation is speed-reduced depending on the number of the magnetic poles of the rotary members 4-7. |
