A tape cartridge which, in a state in which a reel cannot rotate, restricts movement of a braking member and restricts movement of the reel. In a state in which engaging walls of locking members are engaged with a top edge portion of a reel hub, step portions and the engaging walls abut a top surface of an upper flange and an inner peripheral surface of the reel hub. In this way, when the cartridge is not in use, vertical direction movement of the reel is restricted. Even if impact of a drop or the like is applied to the recording tape cartridge (10), the reel does not rise up. Accordingly, a problem such as the braking member tilting and becoming anchored does not arise. It is also possible to overcome a problem of the upper flange or a lower flange of the reel braking due to the reel moving within a case when the tape cartridge is dropped.
