PROBLEM TO BE SOLVED: To provide a technique capable of simply integrating a plurality of plate-like members constituting a stator while preventing an external diameter of the stator from being increased and preventing a flux path from being narrowed.SOLUTION: A stator 140 of a dynamo-electric motor 100 is constituted by a plurality of laminated plate-like members. The plurality of laminated plate-like members are integrated by pressing an axial member 160 into a hole 150 formed on each plate-like member. An inner peripheral surface 150A of the hole 150 and an outer peripheral surface 160A of the axial member 160 are configured not to come into contact with each other at a position J1 along the inner peripheral surface 150A of the hole 150, where a line S1 connecting the position and a center of rotation O is vertically crossed to a tangential line R of the inner peripheral surface 150A of the hole 150 at the position and a stress for inflating the position from the center of rotation O toward a direction of an outer peripheral surface 140A of the stator 140 is generated when the inner peripheral surface 150A of the hole 150 and the outer peripheral surface 160A of the axial member 160 come into contact with each other at the position.SELECTED DRAWING: Figure 2 |
