Abstract
An internal rotor-type fluid machine includes a rotary shaft, a rotor which rotates together with the rotary shaft, a support portion which is provided on the rotary shaft or the rotor, and which supports the rotary shaft to be tiltable with respect to the rotor, and a pressure chamber inner wall surface which configures a pressure chamber by contacting an end surface of the rotor in an axial direction. The rotor is pressed toward the rotary shaft by a high fluid pressure, based on a pressure difference in the pressure chamber between a high pressure side and a low pressure side having a lower pressure than the high pressure side. The support portion is deviated in a direction away from the pressure chamber inner wall surface further than a center position of the rotor in the axial direction.
