PROBLEM TO BE SOLVED: To provide a resolver rotor capable of reducing press-fit stress generated in the resolver rotor and capable of sufficiently securing press-fit area of the resolver rotor to a shaft.SOLUTION: A resolver rotor 50 of a resolver 15 for detecting a rotation angle of a shaft 8 of a motor 1 includes: an annular rotor body 21 to be press-fit to an outer peripheral surface of the shaft 8; a plurality of protrusion parts 22 formed on an outer peripheral surface 21a of the rotor body 21 equally in a peripheral direction and protruded to the diameter-direction outside; positioning holes 23 formed at least alternately on the plurality of protrusion parts 22; and notch parts 24 formed on positions facing the positioning holes 23 on an inner peripheral surface 21b of the rotor body 21. |
