Abstract
A recording tape cartridge enabling proper assembly of a brake member which blocks rotation of a reel during non-use. A magnetic tape is wound on a reel accommodated in a case. The brake member is non-rotatably supported in the case and moves toward/away from a base portion inside a reel hub. Rotation of the reel is disabled when a brake gear provided at a disc portion meshes with gear teeth, and rotation is enabled when this meshing is released. Tapering walls stand along a circular periphery larger in diameter than an outer diameter of the brake member and coaxial with the hub. When the brake member is being inserted into the hub, the brake member is guided, at the disc portion and at a rim portion extending out from the disc portion, by the tapering walls to a position at which the brake gear meshes with the gear teeth.
