The invention relates to a technical apparatus, in particular an electromechanical drive for the moving of information carriers, having at least one plastic functional part (25a) which is formed on a baseplate by injection-moulding on to the latter by the outsert-moulding technique and comprises at least one web (28), which reaches through an opening (23) in the baseplate (2), and holding pieces (30, 31), which are located on the baseplate surfaces (2a, 2b), are connected by the web (28) and the plastic of which shrinks after the injection-moulding, the functional part (25a) making itself freely movable by the shrinking as a rotary part or slide of its own accord by virtue of the following design: the holding pieces (30, 31) act only on peripheral subregions (30a, 31a) of the axial web ends (28a) and are at the same time offset with respect to each other in such a way that, with overlapping peripheral subregions (30a, 31a) of the web (28), one web end (28a) on the one plate surface (2a, 2b) always bears only one holding piece (30 or 31) and the other web end (28a), located in the region of overlap, on the other plate surface (2b, 2a) is free from holding pieces (30, 31). <IMAGE> |
