<P>PROBLEM TO BE SOLVED: To provide a rotor capable of suppressing damage of a magnet subjected to a coating process. <P>SOLUTION: The magnet 34 comprises: a permanent magnet material 34a and a plating part 34b formed by applying a plating treatment on an outer surface of the permanent magnet material 34a. A through-hole 36 of a rotor core 33 comprises: an outer protrusion 40 which contacts with the magnet 34 at an outside in a radial direction and an inner protrusion 41 which contacts with the magnet 34 at an inside in the radial direction. The outer protrusion 40 and the inner protrusion 41 are formed in such a manner as to press-fit the magnet 34 at a plating margin portion of the plating part 34b and formed at a position where the outer protrusion 40 and the inner protrusion 41 do not face each other in a contact direction with the magnet 34. <P>COPYRIGHT: (C)2013,JPO&INPIT |
