<P>PROBLEM TO BE SOLVED: To improve detection accuracy of a rotational-position in a structure for fixing rotational-position detection rotor, where the rotational-position detection rotor is caulked and fixed to a shaft. <P>SOLUTION: A resolver rotor fixing structure includes a resolver rotor 28 having, on its outer circumference, an outer detection face 42 for detecting the rotational position; and a rotor shaft to which the resolver rotor 28 is fitted. The resolver rotor 28 is caulked and fixed to the rotor shaft with a caulking section provided to the rotor shaft. A slit 56 is formed to a position radially outside than a contact section at a position axially matching the contact point with the caulking section in an axial end at the caulking section side of the resolver rotor 28. <P>COPYRIGHT: (C)2012,JPO&INPIT |
