Abstract
A technical device, in particular an electromechanical running gear for the movement of information carriers, such as magnetic tapes or discs, having a carrier plate (1) made of metal at which movable functional parts (5, 7) made of synthetic resin are formed by an injection molding process (outsert molding). Each functional part is held in a respective hole (3, 4) in the plate by means of retaining pieces (5a, 5b, 7, 7c) made of synthetic resin which overlie both plate surfaces (1c, 1d). The retaining pieces are interconnected through the hole by an integral synthetic-resin connection bridge (5b, 7b) integral with these pieces. Clearance sufficient to obtain a smooth movement of the functional parts (5, 7) in the holes (3, 4) is obtained through mechanical deformation of the retaining pieces subsequent to the insertion molding. The holes 3, 4 are formed such that the parts 5, 7 may be outsert molded with the parts free of contact with each other yet moveable after molding into continuous engagement with each other.
