ABSTRACT:
In a positioning apparatus (40), a fixed scroll (34) is positioned with respect to an assembly body (11) in which a compressor motor (25) has been incorporated. In positioning the fixed scroll (34), electric power is supplied to the compressor motor (25) from an inverter (81) to rotate a crank shaft (20) by the compressor motor (25), thereby shifting a movable scroll (31). In the positioning apparatus (40), the shift of the movable scroll (31) leads to calculation of an appropriate position of the fixed scroll (34). A striking unit (70) applies impact force to the fixed scroll (34) to stir the fixed scroll (34) to the appropriate position.
