Abstract:
1. A stator of a generally hollow cylindrical shape, comprising: a plurality of stator core segments arranged adjacent to one another in a circumferential direction of said stator and each having an outer surface on the outer side of said stator in a radial direction; the same number of curved members as said stator core segments, said curved members having a plate shape which is curved in said circumferential direction, and each having a projecting portion curved to project toward said outer surface, contacting said outer surface and pressing said outer surface inward in the radial direction of said stator; and a wall of a cylindrical shape surrounding an outer circumference of said stator, said curved members being interposed between said stator core segments and said wall, and said curved members being sandwiched by said stator core segments and said wall in a flexed state so as to be reduced in size in said radial direction, and exerting an inward stress in said radial direction on said stator core segments and an outward stress in said radial direction on said wall.
