ABSTRACT:
A pressure spring for tape cassettes which consists of a spring steel strip which is, in particular, narrow and is of roughly uniform width comprises a flat central part and curved spring arms adjacent to said part and having a continuous curve. The flat central part has, as fastening parts, holes with indented fastening collars which, together with rivet pegs and recesses in a housing wall, form a roughly projection-free spring fastening, the riveted peg ending roughly at the spring surface. The pressure spring exhibits a straight line with a defined slope in the operating region of its spring characteristic. The pressure spring can be used for tape cassettes of all types, in particular for video cassettes.
