機械。 A fixed scroll 2 and a movable scroll 3 are disposed in opposition on one side of the casing 1 via a frame 4, and a motor 5 is disposed on the other side. A scroll-type fluid machine that supports a drive shaft 6 coupled to a rotor 52 of the motor 5, and in which an eccentric portion 61 provided at the shaft end of the drive shaft 6 is fitted into a fitting portion 31 provided on the movable scroll 3. A balance weight 8 is integrally provided at an intermediate portion of the drive shaft 6 between the rotor 52 and the bearing 7 to counter the centrifugal force of the movable scroll 3 rotated eccentrically by the eccentric portion 61, The eccentric part 61 and the fitting part 3
1, an axial gap T1 is provided between the drive shaft 6 and the movable scroll 3 to allow the movement of the drive shaft 6 in the axial direction. A scroll-type fluid machine characterized by facing each other with a clearance T2 smaller than an axial clearance T1.
