Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the durability of seals and washers, and to extend the service life of parts, by obtaining a bearing assembly to prevent the air leakage between a stator vane system and a compressor casing. SOLUTION: Numerous layers of seals 204 and washers 220 to seal between a vane system 246 and a casing 204 are provided in a turbine engine. The seals and the washers are manufactured by a material such as a glass fiber, and they are impregnated in a polyimide resin. Such a seal and washer have a good durability, and a low friction coefficient.
