Abstract

PURPOSE: To eliminate eccentricity of the thrust force acting between a revolving scroll member and a bearing part to bear it, by providing the sliding surface of the revolving scroll member or that of the thrust bearing part with an inclined surface.
CONSTITUTION: Scroll members 3.6, which are formed by spiral laps 2.5 consisting in an involute curve upright in mirror plates 1.4, are put in engagement with each other. One of the revolving scroll members 6, make revolutions under the condition that rotation around its axis is hindered, and has a bearing part to bear the thrust force of the revolving scroll member 6. The sliding surface of the revolving scroll member 6 or that of the bearing part to bear this member 6 is provided with a groove 13 in the form of a wedge in order to cancel the thrust force.
