ABSTRACT:
To provide a tape cartridge capable of preventing an area near the posterior rim a tape winding layer from colliding with a casing wall to cause the tape edge to be damaged upon reception of dropping impact in the state where the upper and lower sides of the tape cartridge are reversed, so that the magnetic tape can constantly be maintained in an appropriate state. A pair of right and left hubs for taking up the magnetic tape, a hub locking structure are provided inside a main casing. The hub locking structure is placed on the anterior side of the inner surface of an upper casing in the main casing. A regulating body for regulating inclination of the tape winding layer is formed so as to bulge on the rear side of the inner surface of the upper casing. The regulating body is formed in an oblong rib shape having a bulge size almost identical to a thickness size of the hub locking structure in the inner surface of the upper casing. A flank for avoiding collision with the tape winding layer is formed in a side edge corner of the regulating body. The flank is formed by rounding the end section of the regulating body.
