Abstract:
1. A recording tape cartridge comprising: a reel, a recording tape being wound around an outer periphery of a cylindrical tubular hub provided at an axially central portion of the reel; a case having a ceiling plate and a floor plate which oppose one another, the reel being accommodated in the case so as to be able to move along an axial direction between the ceiling plate and the floor plate; and a locking member able to be set at a restricting position, at which, in a state in which the reel is shifted toward the floor plate, the locking member is disposed between a ceiling plate side end portion of the reel and the ceiling plate and restricts axial direction movement of the reel, and a restriction releasing position, at which the locking member is withdrawn from the restricting position and permits the axial direction movement of the reel, wherein, when the locking member is positioned at the restricting position, among surfaces of the reel which face toward the floor plate, only a portion which is positioned further toward a radial direction inner side than an outer peripheral surface of the hub abuts the case.
