Abstract: A rotor is provided with: a rotor core (32); a plurality of permanent magnets (33); a substantially tubular magnet cover (71); and a load reception block (70). The rotor core (32) rotates integrally with a rotary shaft of a motor. The permanent magnets (33) are arranged on the outer peripheral part of the rotor core (32). The magnet cover (71) covers the exterior of the plurality of permanent magnets (33) and the rotor core (32), and has a flange part which is bent radially inward at the end along a rotation axis. The load reception block (70) is disposed between the flange part and the end surface of the rotor core (32) in a direction along the rotation axis, and abuts against the flange part and the rotor core (32).
