Beschreibung
Zusammenfassung:	The gas laser oscillator apparatus of the present invention has a temperature-detecting mechanism disposed at the bearings of the bellows section. The temperature-detecting mechanism detects temperature rise in the bearings and calculates a maintenance cycle with reference to the predetermined data on relationship between temperature and the lifetime of the bearings. Disposed at the bearings, the temperature-detecting mechanism outputs a signal that indicates a replacement cycle according to the temperature of the bearings. More preferable, the temperature-detecting mechanism has a sensor at a tip end of a spring having a pressure force smaller than a load applied to the bearings in advance. To enhance accuracy of temperature detection, the spring is wrapped around with heat insulating material so as not to be exposed to outside temperature.
