Claims

[Scope of Claim for Utility Model Registration] 1. A braked part that is provided integrally with a reel hub around which a magnetic tape is wound and has directional unevenness on its circumferential surface;
It comes into contact with the directional unevenness, which is separably provided, and allows rotation in the tape winding direction and restricts rotation in the direction of loosening the tape. A tape cassette having a braking mechanism including a braking portion having uneven portions formed in different directions. '2 The directional uneven portion is elastically bent by the pressure of the braking unit, and the elastic restoring force of the bent portion is used to provide a force that urges the reel to rotate in the tape winding direction. A tape cassette according to claim 1 of the utility model registration claim.
