ABSTRACT:
A tape cassette comprises a pair of reels, and a cassette case for rotatably accommodating the reels. Each reel has a reel hub which is wound with a magnetic tape, a center hole and reel flanges provided on the reel hub. The cassette case has a pair of support parts for rotatably supporting the reel hubs of the reels so that the reels can rotate in a state where the reel flanges of the reels are separated from inner surfaces of the cassette case. Each of the support parts is constituted by a pair of annular projections formed on peripheries of two corresponding holes in the cassette case. Each annular projection projects toward the inside of the cassette case, and supports a corresponding one of the reel hubs solely by a tip end thereof.
