PROBLEM TO BE SOLVED: To provide a non-contact feeding method for transport cars in a transporting system in which the load change of the voltage of the primary side power supply is reduced to feed transport cars by a non-contact method. SOLUTION: This is a non-contact feeding method for transport cars 2a, 2b in a transporting system 1 in which, with a conductor 5 connected to a power supply 3 structuring the primary side, electric power is fed to transport cars 2a, 2b by a non-contact method via a secondary side pickup coil by using the phenomenon of electromagnetic induction caused by the current flowing in the primary side conductor 5. The reactance of the secondary side resonance circuit of the pickup coils mounted on the transport cars 2a, 2b is made to become inductive and capacitive for each transport car. As a result, the effect of a load for each transport car on the primary side power supply 3 is offset with each other.
