Abstract
A recording tape cartridge in which a reel includes a reel gear and an engaging gear. The reel gear is formed in an annular shape at an outer face of a base portion of a reel hub. The engaging gear is formed in an annular shape at an inner face of the base portion. Magnetic tape is wound onto an outer periphery of the reel hub. A braking member is engaged with the engaging gear by an urging force and prevents the reel from rotating. A clutch member opposes a gear aperture at a radial direction inner side relative to the reel gear. An operationally pushed surface of the clutch member is pushed by a releasing surface of a drive device and the brake member is lifted, whereby rotation of the reel is enabled.
