Claims

[Scope of utility model registration request]

A reel hub having locking teeth formed on the outer periphery, a reel brake lever having an engaging pawl that engages with the teeth of the reel hub to prevent rotation of the reel, and a reel brake lever provided on the cassette case to rotate the reel brake lever. In the tape cassette, the tape cassette includes a fulcrum pin that is movably supported, and a torsion spring that is fitted onto the fulcrum pin and biases the reel brake lever in the engaging direction; A tape cassette characterized in that a torsion spring that also serves as a compression coil spring is interposed between a brake lever and the cassette case.
