造。 The bearing support structure for the shaft is supported within the casing via a bearing for a normal thrust load and a bearing for a reverse thrust load, receives a reverse thrust load at startup, receives a normal thrust load during operation, and is subject to temperature rise. A preload spring made of a shape memory alloy whose natural length is longer at high temperatures than at low temperatures, between the side surface of the outer race of the reverse thrust load bearing on the side of the positive thrust load bearing and the casing;
A bearing support structure characterized in that one or both of a preload spring made of a shape memory alloy whose natural length is shorter at high temperatures than at low temperatures is provided between the opposite side surface of the outer race and the casing. .
