ABSTRACT A tape cassette dust door polar member, a dust door spring assembly and a related method for manufacturing and assembling the dust door spring assembly. The dust door polar member has a fixed end and a rounded free end. The rounded free end has a wide slit and a narrower slit extending therefrom toward the fixed end. The dust door spring assembly comprises this polar member and a spring having a short first leg and a long second leg angled relative to each other. The short first leg of the spring is positioned within the second slit of the polar member and the second leg of the spring is urged against the dust door to effect torsion of the spring. In the method of assembly, the wide and narrow slits of the dust door polar member sequentially receive the first short leg of the spring and twist the spring in a clockwise direction, to urge the second long leg against the dust door to effect torsion. This dust door polar member, dust door spring assembly and method for manufacturing and assembling the dust door spring assembly provide more efficient production and automated assembly of tape cassettes.
