Claims

[Scope of utility model registration request]

In a magnetic tape cassette that has an opening for inserting a magnetic head on the front surface of a cassette case in which a pair of hubs wrapped with magnetic tape are built in, the upper and lower outer surfaces of the left and right cassette side walls are placed near the front of the cassette. The bearing has a cassette case with an inclined wall surface that extends vertically symmetrically in front of the cassette with respect to a line that is doubled, and a horizontal cross section is approximately U-shaped, and the bearing is located inside each of the left and right end pieces. a guard panel that is swingable up and down and that has a rotational shaft that engages with the end piece and that can swing up and down to close the opening; and a biasing means for biasing the guard panel toward the rear of the cassette, and the entire cassette is symmetrical from front to back.
