Abstract
There is provided a resolver rotor in a resolver provided to a rotating electrical machine. The resolver rotor is formed from an annular body. A phase determination hole for setting a relative position to a shaft of a motor is provided at a near outer peripheral portion of the resolver rotor. A virtual circle is set which comes into contact with a section of the phase determination hole at a proximal end to an inside diameter of the resolver rotor, and has a center point coincident with the center of the resolver rotor. A pair of hole portions are arranged at portions extending from the virtual circle to an outside diameter side of the resolver rotor while taking in the virtual circle.
