    • 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.
    • 在卷轴不能旋转的状态下的带盒限制制动部件的移动并限制卷轴的移动。 在锁定构件的接合壁与卷轴毂的顶部边缘接合的状态下,台阶部分和接合壁抵靠上凸缘的顶表面和卷轴毂的内周表面。 以这种方式,当盒不使用时,卷轴的垂直方向运动受到限制。 即使对记录带盒(10)施加液滴等的影响,卷轴也不升起。 因此,不会产生诸如制动构件倾斜并变得锚定的问题。 也可以克服当带盒掉落的情况下卷盘移动时卷盘制动的上凸缘或下凸缘的问题。
