Claims

[Claims for Utility Model Registration] Consisting of a pair of tape reels wound with magnetic recording tape and a cassette housing housing the pair of tape reels, the magnetic tape cassette is loaded into a tape deck at the bottom of the cassette housing. In a magnetic tape cassette provided with a lock release hole into which a lock release member on the tape deck side enters when the tape deck is opened, the pair of tape reels are provided with a locking portion consisting of a large number of recesses on the outer periphery of the flange, and the cassette is The housing is made of a single piece of resilient material formed into a substantially α-shape and has a brake member provided at both ends with locking pawls that engage with and disengage from the locking portion, the brake member is configured such that the locking pawl is movable between an engagement position where it engages with the locking portion and a disengagement position where it disengages from the locking portion, and the lock release member that enters through the lock release hole. The locking pawl is disposed near the lock release hole so that the inner surface is in contact with the lock release hole, and when the inner surface is pushed and deformed by the lock release member, the locking pawl is in the detached position and released from the lock release member. A magnetic tape cassette, characterized in that the locking pawl is installed in the cassette housing so that the locking pawl is in the engagement position when the magnetic tape cassette is restored.
