PROBLEM TO BE SOLVED: To provide a noncontact power feeding equipment capable of reducing induced current and improving efficiency of a system. SOLUTION: Along a moving line of a putting in/out device 10, an induction line 43 for making high frequency current supplied from an inverter M to flow is laid. The putting in/out device 10 is provided with a motor 29 for traveling to which power is fed from the induction line 43 by a noncontact via a pickup coil 55 and a crane controller 77 for driving the motor 29 for traveling, controlling moving of the putting in/out device 10 and outputting the moving state data. The inverter M is constituted so that a current value flowing in the induction line 43 may be changed based on the moving state data outputted by the controller 77. By the constitution, induced current required at the time of acceleration or deceleration of the motor 29 for traveling is supplied and induced current feeding power to the induction line 43 at the time of constant speed and a stop is reduced. As a result, an average value of current flowing in the induction line 43 can be reduced.
