ABSTRACT:
The present invention relates to an elastic element structure for the reel retention ratchet gear in magnetic tape cassettes which comprises an elastic lamina with elongated extension defining a central portion for coupling to a magnetic tape cassette and two opposite branches acting, at their free end, on the respective thrust arms of the reel retention ratchets. The peculiarity of the invention resides in the fact that it comprises, at said free ends, shapings adapted to generate a thrust component in the direction of elastic preloading of said elastic lamina upon the insertion of said ratchets in said cassette along a direction substantially coinciding with their axis of oscillation.
