Abstract
A rotary electric machine equipped with a magnetic flux variable mechanism includes a case body, a mover moving upon receipt of centrifugal force, a magnetic flux short circuit member, a cam member, and biasing springs. The cam member includes a cam surface so as to face the mover and make contact with the mover, and the cam member converts a radial movement of the mover received by the cam surface into an axial movement of the magnetic flux short circuit member. The biasing springs give a biasing force to the magnetic flux short circuit member in a direction distanced from an axial end surface of the rotor core, so as to determine a position of the magnetic flux short circuit member along the axial direction in a state where the biasing force is balanced with the centrifugal force applied to the mover via the cam member.
