ABSTRACT:
A pinch roller assembly for use in a video cassette recorder, which comprises: a pinch roller, a supporting shaft provided with a cylindrical section and a spherical portion protruding therefrom, a sleeve having an upper section, a lower section and a contact section joining them together, and a bush provided with a tapered surface. The spherical portion of the supporting shaft comes into a loose contact with the contact section of the sleeve and the tapered surface of the bush, and there exist gaps between the cylindrical section of the supporting shaft and the upper section of the sleeve and between the cylindrical section of the supporting shaft and the inner surface of the bush, respectively, to thereby allow the pinch roller to pivot about the spherical portion of the supporting shaft and to realign itself to be parallel with respect to a capstan shaft while it presses against a capstan shaft.
