Abstract
A tape cassette includes a pair of pinch rollers 118, 119 for guiding a magnetic tape T movably provided in a cassette opening 75 of shell body 71. Both ends of a roller shaft 124, 125 rotatably supporting each pinch roller 118, 119 are supported, and there are provided, around middle portions of these roller shafts, receiving portions 120b, 121b swingably holding the pinch rollers 118, 119. Therefore, the receiving portions 120b, 121b provide the self aligning effect of the pinch rollers 118, 119 with respect to the roller shafts 124, 125. Accordingly, it is possible to mitigate the dimensional accuracies and installation accuracies of component parts, and to prevent each roller shaft from being deflected by the pressure of a capstan.
