PROBLEM TO BE SOLVED: To stick an outer yoke and an inner yoke fast to each other, under the conditions that the body of a dynamo-electric machine be mounted to the outer yoke, even if the accuracy of the mounting dimensions between the outer yoke and the inner yoke is not set precisely. SOLUTION: A swallow-tailed tongue piece 8 is made at one end of an outer yoke 7 consisting of a sheet of strip piece, and a roughly analogous cut 9 a little smaller than the tongue piece 8 is made at the other end. The outer yoke 7 is made into a tubular form, by pushing the tongue piece 8 into an opening and temporarily engaging both with each other. The outer yoke 7 is enlarged in diameter to agree with the outside diameter of the main body 2 of a motor, when the body 2 of the motor is mounted, and the joint 10 between the tongue piece 8 and the cut 9 is a transformed slightly, thereby engaging both firmly. Therefore, the inner yoke 5 of the body 2 of the motor and the outer yoke 7 will be stuck fast to each other without fail.
