    Abstract: A turbo machine of the present disclosure includes a cylindrical bearing housing, a rotation shaft, a bearing, a bearing holder, and an end elastic body. The rotation shaft is located in the bearing housing. The bearing rotatably supports the rotation shaft at least in a radial direction of the rotation shaft. The bearing holder faces one end of the bearing and is fixed to the bearing housing. The end elastic body is disposed between the one end of the bearing and the bearing holder in the axial direction of the bearing and is in contact with the bearing and the bearing holder. The end elastic body is formed of a material having a lower modulus of elasticity than a material forming the bearing holder.

    Abstract: A turbomachine for a refrigeration cycle apparatus that uses a refrigerant whose saturated vapor pressure is a negative pressure at ordinary temperature includes a rotation shaft and a bearing for supporting the rotation shaft. The rotation shaft includes a lubricant supply passage for supplying the refrigerant as a lubricant that travels smoothly between the rotation shaft and the bearing. The lubricant supply passage includes a main passage and a sub-passage. The main passage extends from an inlet located at an end of the rotation shaft in an axial direction of the rotation shaft. The sub-passage diverges from the main passage and extends to an outlet located in a side surface of the rotation shaft.
