PROBLEM TO BE SOLVED: To secure an iron core and a casing firmly, without causing any deformation of the iron core in the radial direction.SOLUTION: A stator (20) of an electric motor (1) includes an iron (21) and a casing (25), and the iron core is divided into a plurality of core components (21a, 21b) in the direction of the rotation axis. A first core thread (31a) of a right screw is formed in the inner or outer peripheral surface of at least one of the plurality of core components, and a second core thread (31b) of a left screw is formed in the inner or outer peripheral surface of other core component adjacent to the at least one core component. In the outer or inner peripheral surface of the casing, a first casing thread (35a) screwing to the first thread of at least one core component, and a second casing thread (35b) screwing to the second core thread of other core component are formed. |
