Patent ID: 8006379

Claim:
An apparatus, for use in an assembling process of a scroll fluid machinery, for positioning a fixed scroll on the basis of a positional relationship between a rap of the fixed scroll and a rap of a movable scroll, the apparatus, comprising: a fixing member for fixing an assembly body of an integrated combination of the movable scroll, a crank shaft engaged with the movable scroll, and a housing member composing a bearing of the crank shaft; a pressing mechanism for pressing the fixed scroll engaged with the movable scroll against the housing member; a determining unit configured to determine a stirring distance and a stirring direction of the fixed scroll; a stirring mechanism for stirring the fixed scroll according to the stirring distance and the stirring direction which are determined by the determining unit by applying impact force to the fixed scroll being pressed against the housing member; and a guide, provided in the pressing mechanism, for inhibiting the fixed scroll from rotating while allowing the fixed scroll to stir in parallel to an X axis direction or a Y axis direction which intersect at a right angle with each other, wherein the X axis direction and the Y axis direction in which the guide allows the fixed scroll to stir agree with directions of the impact force that the pressing mechanism applies to the fixed scroll.
