When assembling divided iron cores, there was a problem in that multiple positioning steps were required, which led to an increased number of steps and more complex facilities, thereby causing an increase in processing costs.　According to the present invention, when joining a first divided iron core and a second divided iron core together, a first protrusion of the first divided iron core and a second recess of the second divided iron core are brought close to each other in the circumferential direction and and made to contact each other in a state of having the first divided iron core and the second divided iron core be offset in the height direction, after which one or both of the first protrusion and the second recess are slid in the height direction, whereby a first groove portion of the first divided iron core and a second tenon portion of the second divided iron core are engaged with each other, and a first tenon portion of the first divided iron core and a second groove portion of the second divided iron core are engaged with each other.
