Abstract:
This rotating electric machine is so formed that the length from an end portion of a rotor core closer to a rotating shaft support portion to a portion first coming into contact with the rotating shaft support portion when a rotating shaft portion is inserted into the rotating shaft support portion is larger than the length from an end portion of the rotating shaft support portion closer to a stator to an end portion of a stator core opposite to the rotating shaft support portion.
