PURPOSE:To reduce a gap between a coil and support to a minimum extent and improve a tightness between them by a method wherein a charge containing immersed vanish is inserted to the space between the coil and support and a thermal contraction is utilized by providing a welering for the support when the vanish is changed into a gel. CONSTITUTION:A coil 3 is fixed by a support 2, the charge containing immersed vanish is provided between the coil 3 and support 2 for example to a grease cloth. The weldering for the support 2, 1 begins at the time which the vanish is changed into a gel after for a while. In this time, the supports 1, 2 are tightened strictly through a thermal contraction, since the vanish changing into the gel is tightened satisfactorily to the concave portion, and excessive vanish is discharged from the end, whereby obtaining a coupling excellent in a tightness and having a remarkably reduced gap. |
