Rotor of rotary electrical machine and motor

A rotor of a rotary electrical machine, comprising:

• a rotor iron core having an axis line;
• and
• a plurality of magnets provided in the rotor iron core, wherein
• the rotor iron core includes first and second iron cores which are stacked mutually in a direction along the axis line;
• the first iron core includes a first iron core main body and a plurality of first projecting sections which project to a radial outer side from an outer circumferential section of the first iron core main body and are arranged at intervals apart from each other in a circumferential direction of the first iron core main body;
• the second iron core includes a second iron core main body, which overlaps with the first iron core main body, and a plurality of second projecting sections which project to a radial outer side from an outer circumferential section of the second iron core and are arranged at intervals apart from each other in a circumferential direction of the second iron core main body, in concordance with positions of the first projecting sections;
• in the rotor iron core, a rotor iron core main body is configured from the first and second iron core main bodies, and projections are configured by the first and second projecting sections which are aligned in a direction along the axis line;
• the magnets are provided in an outer circumferential section of the rotor iron core main body in a state of being arranged between the projections;
• when the rotor iron core is viewed along the axis line, portions of the second projecting sections protrude as extension parts outward in the circumferential direction, from the first projecting sections;
• when the rotor iron core is viewed along the axis line, radial-direction outer side end surfaces of the extension parts are smoothly continuous with radial-direction outer side end surfaces of the first projecting sections;
• and
• spaces are generated between the circumferential-direction end surfaces of the first projecting sections and the permanent magnets.
