PROBLEM TO BE SOLVED: To provide a non-contact power transmission interruption apparatus in which the impact or wear does not occur and which has no transmission loss. SOLUTION: This non-contact power transmission interruption apparatus comprises: an input shaft coil 4 attached on an input shaft 2; an output shaft coil 5 attached on an output shaft 3 which is arranged so as to be coaxial with the input shaft 2; a power supply circuit 6 which applies a current on either one of the input shaft coil 4 or the output shaft coil 5; a takeout circuit 7 for taking out an inductive power from the remaining one of the input shaft coil 4 or the output shaft coil 5; an outer yoke 8 which is attached on the input shaft 2 so as to introduce magnetic lines of force to the input shaft coil 4 and covers the outer periphery of the output shaft 3; and an inner yoke 9 which is attached on the output shaft 3 so as to introduce magnetic lines of force to the output shaft coil 5 and faces the outer yoke 8 from the inner periphery. In the inner yoke 9, one part thereof is configured to be movable so that a gap between the inner yoke 9 and the outer yoke 8 is narrowed according to increase in rotational speed of the output shaft 3.
