プカセツト。[Claims for Utility Model Registration] A reel lock member that has teeth formed on the outer periphery of a pair of reels that are rotatably housed in a cassette housing, and a pair of locking pawls that are respectively engaged with the teeth. is pressed by the biasing means to slide toward the intermediate portion of the two reels, thereby engaging the pair of locking pawls and causing the two teeth to restrict rotation of the two reels in the tape payout direction. In the tape cassette provided with the reel lock member, the biasing means includes a coil spring having at least one end a tightly wound portion having a winding diameter larger than the winding diameter of the central spring portion; A pair of protrusions facing each other with an interval smaller than the winding diameter of the tightly wound portion of the coil spring is provided on the opposite side of the locking pawl, and the tightly wound portion of the coil spring is engaged with the pair of protrusions. A tape cassette, characterized in that the tape cassette is attached to the reel lock member by locking the tape cassette.
