PROBLEM TO BE SOLVED: To obtain a dynamo-electric machine in which deformation of a stator core is prevented in the radial direction, while preventing the occurrence of displacement of stator core.SOLUTION: The dynamo-electric machine includes a cylindrical housing 1 provided with a radial through hole 13 into which a fixing pin 5 is inserted, a spacer 2 placed on the inner peripheral surface of the housing, and provided with a hole 21 at a position corresponding to the through hole 13, and a stator core 3 held in the housing while being fitted therein with the spacer interposed therebetween, and provided with a recess 33 corresponding to the hole on the outer peripheral surface. A gap is formed between the tip in the insertion direction of the fixing pin entering the recess, and the bottom face of the recess. The inner peripheral part of the hole in the spacer is deformed plastically by insertion of the fixing pin and enters the recess. |
