A generator housing has a cast cup-shaped member which has an axis and an open end closed by a bearing plate. A cylindrical portion of the cup-shaped member is provided with three protuberances angularly spaced 120 DEG apart from each other about the axis of the cup-shaped member. Each protuberance extends the entire axial length of the cylindrical portion of the cup-shaped member and is provided with a longitudinal passage therethrough to receive through-bolts for holding the housing in a predetermined position. The bearing plate is formed with through openings aligned and communicating with the passages, the through-bolts also passing through the respective openings.
