Abstract

PURPOSE:To improve the uniformity of a tightening force and to decrease the manhours by diving the yoke to be provided on one side of main legs by other magnetic member so that they can be moved, and giving free displacement of each main leg in the axial direction in the tightening step. CONSTITUTION:The upper yoke is divided into portions corresponding to the number of the main legs, and the divided upper yokes 25-27 are placed on the main legs 5-7. Gaps 3a are provided between the yokes 25 and 26, and yokes 26 and 27. Gap forming materials 3a' are inserted into said gaps. In this constitution, even though the difference in the lengths in the axial direction is caused between the individual main legs 5-7, the tightening can be separately performed by tightening devices provided between yokes 25-27 and a lower yoke 2. Therefore, the fine adjustment of the lengths in the axial directions of the main legs 5-7 is not required, manufacturing manhours are decreased, and furthermore, the main legs can be tightened with a desired uniform pressure.
