Claims

[Claims for Utility Model Registration] In a sealed case, an electric motor; a bearing support member fixed to the case and supporting the upper part of the drive shaft of the electric motor; and a bearing support member connected to the drive shaft and eccentric to the drive shaft. a fixed-side scroll member fixed to the case; and a fixed-side scroll member connected to the crankshaft and engaged with the fixed-side scroll member as the crankshaft is driven to perform an eccentric movement to generate an intake pressure chamber, an intermediate pressure chamber, and a fixed-side scroll member. A movable scroll member that defines a discharge pressure chamber; an autorotation prevention mechanism that prevents rotation of the movable scroll member; and a rotation prevention mechanism that is provided on the movable scroll member and connects the discharge pressure chamber and the back side of the movable scroll member. A scroll fluid machine characterized by comprising communicating small holes.
