There is provided a rotor for a rotary electrical machine for improving mechanical strength of the rotor against centrifugal force. The rotary electrical machine is provided with a stator, and a rotor disposed with a gap from the stator, which has a rotor core. The rotor includes a magnet insertion hole, and a permanent magnet inserted into the magnet insertion hole. A clearance part is formed at a position of the magnet insertion hole corresponding to a corner of the inserted permanent magnet, which has a facing surface that is formed to face a surface of the permanent magnet via a gap. The facing surface of the clearance part has inflection points so that each of obtuse angles is formed by the two facing surfaces contiguous with the inflection points.
