A retarder-equipped rotating electrical machine includes a rotor, a stator, and a retarder rotor. The stator has teeth at regular intervals in a circumferential direction. One ends of the teeth are disposed to face the rotor. The retarder rotor has a magnetic member continuously in the circumferential direction. The retarder rotor is disposed to face the other ends of the teeth of the stator and configured to rotate integrally with the rotor. A rotor-to-stator pole piece portion having pole pieces at regular intervals in the circumferential direction is disposed between the rotor and the stator. A stator-to-retarder rotor pole piece portion having pole pieces at regular intervals in the circumferential direction is disposed between the stator and the retarder rotor. Both pole piece portions are moved in the circumferential direction to switch between an operation as a motor or generator and an operation as a retarder.
