Rotating electric machine

A rotating electric machine comprising:

• a rotor that is fixed to a rotation shaft;
• a stator that generates an alternating current as the rotor rotates;
• a frame member that holds the rotor and the stator;
• a rectifier that is fixed to an outer side of the frame member and constituting a rectification circuit that rectifies the alternating current generated by the stator;
• and
• an insulating cover that is provided so as to cover the rectifier, wherein
• the rectifier comprises a positive electrode side member that includes a positive electrode side rectification element connected to a power supply side, and a positive electrode side heat sink to which the positive electrode side rectification element is fixed and charged positively,
• the positive electrode side heat sink is disposed so as to face a non-positive electrode side member with a gap between the positive electrode side heat sink and the non-positive electrode side member, the non-positive electrode side member having a potential difference with respect to the positive electrode side heat sink, and
• the insulating cover includes at least one wall portion that extends in a direction in which the positive electrode side heat sink and the non-positive electrode side member are arranged, the at least one wall portion functioning as at least one easily deformable portion that, when the insulating cover is deformed by an external force, contacts with the non-positive electrode side member and enters the gap between the positive electrode side heat sink and the non-positive electrode side member.
