Abstract
A pressure pad device for a magnetic tape cassette comprises a leaf spring having a central fulcrum portion, left and right side portions extending symmetrically from the central fulcrum portion, and each pad attached to each near end of the left and right side portions so as to be equidistant from the central fulcrum portion. A fitting hole is formed at the central fulcrum portion by bending alternately a plurality of strip zones formed in the central fulcrum portion of the leaf spring inwardly and outwardly. The fitting hole is adapted to receive a supporting pole of the magnetic tape cassette and each end of the left and right side portions of the leaf spring is flexibly in contact with each supporting of the magnetic tape cassette.
