PURPOSE: To obtain a supporting apparatus, for a winding end of a stator, which supports a phase ring surely and has an improved strength.

CONSTITUTION: Insulating plates 17 and 18 have a recessed part, corresponding to a shape of an angular phase ring 16, where a gap 19 can be filled with a liner 20. The inner and outer sides of the angular phase ring 16 are secured by the insulating plates 17 and 18 while a liner 20 is inserted into the gap thereof. Then, the insulating plates 17 and 18 are set with a bolt 13 at regular intervals on a plurality of places in an outer circumference of an insulating ring 2. By this means, the overall circumference of the angular phase ring 16 can be uniformly fixed.
