摘要： A reel comprises a hub onto which recording tape is wound and a flange that is disposed on an end portion of the hub and retains a width-direction end portion of the recording tape, wherein plural cutout portions that locally divide the hub and the flange are formed in the flange. The cross section of the hub in plan view has a substantially equilateral triangular shape and positions where constricting force resulting from the tape reaches a maximum are caused to protrude in advance.

摘要： Retention portions that retain a leader member of recording tape are formed inside a case, and a spring member pushes the leader member toward the retention portions. The spring member contacts support point members, and the support point members serve as support points when the spring member deforms. The support point members, which are disposed such that they protrude from side walls of the case, include a height D1 from an inner surface (attachment reference surface) of the side walls. The spring member is bent such that its height at positions contacting the support point members from the attachment reference surface includes a height D2 in a state where the spring member is not attached to the case. Here, D2≦D1. When the spring member is attached to the case, the spring member always contacts the support point members. Thus, the pushing force of the spring member is stable.

摘要： At a reel, an outer peripheral surface of a cylindrical tube portion of a reel hub is a tape winding surface around which a magnetic tape is wound. In a free state, the tape winding surface forms a substantial taper shape in which an outer diameter is greater at an upper end portion side where a radial direction rigidity is relatively low, than at a lower end portion side where the rigidity is high. In a state in which a magnetic tape is wound, the tape winding surface can form a shape that is substantially symmetrical with respect to a transverse direction of the magnetic tape. As a result, the reel and a recording tape cartridge are obtained in which the outer peripheral surface of the hub forms a proper shape in a state in which a recording tape is wound.
