摘要： A reinforcement ring is insert-molded as an insert body on a reel hub of a reel around which recording tape is wound. The reinforcement ring includes a metal ring at least whose inner peripheral surface is covered by a resin layer. The clearance between the reinforcement ring and a mold during reel molding can be reduced, and the amount of eccentricity of the insert body with respect to the reel hub can be reduced.

摘要： In a recording tape cartridge, an inclined opening obtained by notching a corner portion on the side of loading to a drive apparatus is closed when a door is in a close position in which the door is inclined from a direction matching the loading direction and is open when the door is in an open position along a right side wall. The door is guided by first and second guide grooves and moves between the close position and the open position while changing its orientation by a urging force of a compression coil spring disposed along the right side wall or a moving force transmitted from an operation projection which comes into engagement with the engagement member of the drive apparatus.

摘要： In a recording tape cartridge, a reel has a reel hub around which a magnetic tape is wound. An annular reel gear is formed at an outer surface of a bottom portion of the reel hub. Rotation of the reel is impeded by a braking member engaging with an engaging gear formed at an inner surface of the bottom portion. When a clutch member is pressed by a rotating shaft of a drive device, the clutch member is guided by rotation restricting ribs which are engaged with rotation restricting grooves such that relative rotation is impossible, and the clutch member moves in an axial direction of the reel and cancels engagement of the braking member with the engaging gear. A press operation surface and the rotation restricting grooves are positioned further toward a radial direction inner side than the reel gear.
