摘要 <p>A rotor of a rotating electrical machine includes a rotor core which includes an annular core plate formed by coupling a plurality of arc shaped core plate pieces. Multiple core plates are stacked together. A circumferential position of a seam formed by coupling the core plate pieces is alternately displaced for every predetermined number of core plates in a stacking direction of the core plates. A bar-shaped member is inserted in a plurality of through holes formed in the respective core plate pieces and aligned in the stacking direction. Both side surfaces of the rotor core in the stacking direction are interposed between end plates, the end plates contact the core plates, and the end plates do not contact the bar-shaped member at least on a radially outside of the bar-shaped member, which is a side in a direction of a centrifugal force that acts on the bar-shaped member.</p>
