Abstract: An axial-gap rotating electrical machine in which the distance of the air gap between a rotor and a stator can be accurately controlled is provided. A large diameter portion and a small diameter portion are formed on a rotating shaft and a stepped portion is formed therebetween. A rotor yoke is secured thereon and the position of the rotor is determined. The position of a bearing secured in a housing for rotatably supporting the rotating shaft is determined by a boss portion of the rotor yoke. The position of the housing is determined by the position of the bearing and the securing position of the stator is determined by a stepped portion formed on the inner circumference of the housing. Thus the position of the housing relative to the rotating shaft can be determined from the position of the rotor and the securing position of the stator can be determined.
