PROBLEM TO BE SOLVED: To provide an appropriate shielded power coupling device adopting a shield surrounding only a portion when transferring power between relatively rotatable members or adopting a shield divided into a plurality of portion so as to form a gap allowing such relative rotation between the members.SOLUTION: The shielded power coupling device comprises: (a) an induction field generation element capable of converting power into an inductive coupling field; (b) an induction field reception element capable of converting the inductive coupling field into power; (c) an inductive coupling efficiency increase element capable of increasing inductive coupling between the induction field generation element and the inductive coupling field reception element; and (d) a shield around the inductive coupling efficiency increase element. When driving the shielded power coupling device at a power level exceeding 2.5 kW, the shield is capable of substantially removing leakage of electromagnetic radiation from the shielded power coupling device. |
