Abstract
A tape cassette has a pair of cassette halves coupled with each other to form a housing. Each cassette half has a plurality of projections protruding toward the other cassette half. A pair of reel hubs and a magnetic tape wound around the reel hubs are housed in the housing. A pair of liner sheets are arranged individually between the cassette halves and the magnetic tape to hold the magnetic tape elastically on both sides, thereby preventing irregular winding of the magnetic tape. Each liner sheet has a plurality of first protrusions protruding toward each opposite cassette half from those portions of the liner sheet which correspond to the projections of the opposite cassette half and elastically abutting against their corresponding projections. Further, each liner sheet has a plurality of second protrusions protruding toward and elastically abutting against the magnetic tape.
