A drive shaft engaging the orbiting scroll is connected to an electric motor and is supported by a frame. An end plate of the oribiting scroll is slidably held between the frame and an end plate of the fixed scroll. A first feed oil passage is formed in at least one of the end plate of the fixed scroll and the frame. The first passage has one end communicates with an oil reservoir defined at a bottom of the housing and the other end opening on a sliding surface contacting with the orbiting scroll. A second feed oil passage formed in the end plate of the orbiting scroll has one end always communicating with the other end of the first passage. The other end of the second passage is located in the vicinity of the axis of the orbiting scroll. A third feed oil passage formed in the drive shaft has one end communicating with the other end of the second passage.
