Abstract
A tape cassette includes reel hubs which have flanges provided at their peripheral surfaces with engagement portions, and reel lock members, each of which has an engaging portion and is biased so that the engaging portion engages the engagement portion of the flange for preventing rotation of the reel hub. The engaging portion of each reel lock member is provided with a restricting piece for restricting movement of the flange in a direction parallel to the thickness of the flange when the engaging portion is in contact with the engagement portion.
