ABSTRACT:
In a recording tape cartridge, a braking member positioned at a restricting position within a reel hub in a state of abutting an inner surface of a floor plate of a case when the recording tape cartridge is not in use, is held at the restricting position by a top end surface of the braking member abutting a bottom end surface of a clutch member. Upward movement of a reel is restricted. When a release operation portion is pushed by a releasing portion of a drive device and the clutch member rotates, due to cam grooves and cam projections converting torque of the clutch member into axial direction moving force, the braking member, whose held state is cancelled by the bottom end surface sliding along the top end surface, moves to a rising-up permitting position, such that rising-up of the reel within the case is permitted.
