とを特徴とするテープカセツト。 A front cover that allows the front surface of the cassette body to be opened and closed is attached to the cassette body, and a space for disposing the locking member of the front cover is provided between the side wall of the cassette body and the side wall of the front cover. In the tape cassette, a protrusion located below the gap is provided on at least one of the side wall of the cassette body and the side wall of the front lid, and the height of the protrusion is is approximately equal to the width of the space 〓 (
However, if the protrusions are provided on both the side wall of the cassette body and the side wall of the front lid so as to face each other in the width direction, the height of both protrusions up to the opposing part The sum of the widths of the gaps is approximately equal to the width of the gaps.
