A production apparatus sequentially performing given processes to objects to be processed in which a fixture for holding a subsidiary part is set to a main part in a plurality of processing areas (A1 to A6) arranged in a ring formation, and then separating the fixture thereby producing an assembly of the parts. The apparatus comprises a rotational table body (20) rotated by steps of a given angle; a plurality of holding/transferring units (30) arranged in a circumference direction so as to rotate integrally with the rotational table body, and capable of holding the object to be processed, or the assembly of the parts, as well as transferring it onto processing tables within the plurality of the processing areas; a plurality of loading sections (40) provided to the rotational table body correspondingly to the plurality of holding/transferring units, and capable of loading the fixture; and a plurality of processing units (60 to 110) provided to perform the given processes in the plurality of processing areas. Accordingly, miniaturization and cost reduction of the apparatus may be achieved while improving efficiency in producing the assembly of the parts.
