ABSTRACT:
A recording tape cartridge in which melting, abrasion or the like does not occur at a portion of abutting of a brake member with a release member, or with a release portion of a drive device, during rotation of a reel. In this recording tape cartridge, a magnetic tape is wound onto the reel at a reel hub inside a case. A brake member is non-rotatably provided inside the case. The reel is rotation-locked when the brake member is disposed at a rotation-locking position, at which the brake member engages with an engaging protrusion of a bottom portion. A release pad is disposed between the bottom portion and the brake member and abuts against both thereof. When the release pad holds the brake member at a rotation-enabling position, the reel is rotatable. When the reel rotates with the release pad, a metal-formed rubbing protrusion portion of the brake member, which is a convex spherical surface with a radius of at least 3 mm, and a resin-formed rubbing protrusion of the release pad, which is a flat surface, rub against one another.
