ABSTRACT:
A magnetic tape cassette includes a slider fitted slidably along a bottom of a cassette case, as well as resiliently locking pieces formed in the bottom of the cassette case along the bottom in a cantilevered fashion and each having a head at a free end thereof for fitting in an engaging hole in the slider so as to retain the slider. Each of the resiliently locking pieces has a compression coil spring provided between the head 12a and an upper half 11a of the cassette case to maintain a resilient force for the head in a thickness-wise direction of the cassette. When the head is pushed into the cassette case by more than a predetermined amount, coils of the compression coil spring are set in a state of close contact with each other in a compressing direction of the spring so as to support the head from an inward direction of the cassette and positionally restrict the displacement of the resiliently locking piece in the inward direction of the cassette.
