Abstract In a recording tape cartridge, a compression coil spring urges a reel downward via a brake member. Due to the biasing force of the spring, a gear of the brake member securely meshes with a gear inside a reel hub preventing the reel's inadvertent rotation. The biasing force urges lock members outward in a radial direction from the center of a mount or the reel. Engagement portions of the lock members engage with an upper edge of the hub. The outer side surfaces of the engagement portions press against the inner peripheral surface of the hub, and ends of the engagement portions at a further outer side than the body portions intervene between the upper surface of an upper flange and the inner surface of a top plate to prevent rotation of the reel and to control movement of the reel in either a radial or an axial direction.
