を特徴とするテープカセット。A pair of fulcrum pins are integrally provided inside the left and right ends of the front cover, which has a S7-shaped planar shape. The pin is inserted into a pin insertion hole and is rotatably attached, and the front cover is configured to be able to open and close an opening provided on the front surface of the cassette housing by rotating the front cover. A spring locking pin is integrally provided at the fulcrum pin, and the front end side of the torsion coil spring wound around the outer periphery of at least one of the fulcrum pins is locked to the spring locking pin, and the rear end side of the spring is locked to the spring locking pin. In the tape cassette, which is locked to the cassette housing side and whose front cover is rotationally biased in the closing direction by the spring, the tip of the spring locking pin is attached to a circle provided on the side wall of the cassette housing. A tape cassette that is inserted into an arcuate slit and has a flange integrally provided at the tip of the spring locking pin to prevent the spring locking pin from being removed from the slit.
