ABSTRACT:
A tape cassette comprising a pair of case members which are oppositely arranged to form a case body and are each provided with pins at the four corners on the major inner surface, a pair of reel hubs rotatably provided within the case body, and sheet members which are each provided at the four corners with holes and each fixedly attached in place to the major inner surface of the case member in such a manner that the holes receive the corresponding pins on the case member. The interval between each pair of adjacent holes arranged on the sheet member along one of the sides of the sheet member is longer than the corresponding intervals between each pair of adjacent pins arranged on the case member in order that the sheet member bends inwardly within the case body, with the maximally bent center part thereof resiliently contacting the corresponding sides of a tape loaded on the reel hubs.
