Abstract

A reel is provided with a tubular hub, a first flange, a second flange, and positioning portions. A projection portion that projects in a radial direction is formed at an inner periphery face of the hub. The first flange includes a first extension portion which is extended in the axial direction of the hub from a first flange portion and is joined to the projection portion. The second flange includes a second extension portion which is extended in the axial direction of the hub from a second flange portion and is joined to the projection portion. The positioning portions regulate, in the radial direction, positions of distal end portions of the first extension portion and the second extension portion relative to the hub. Gaps are formed between the inner periphery face of the hub and outer periphery faces of the first extension portion and the second extension portion.

Description

technical field [0001] The present invention relates to a reel on which a recording tape such as a magnetic tape is wound, and to a recording tape cartridge equipped with the reel, wherein the recording tape is mainly used as a recording / reproducing medium of a computer or the like. Background technique [0002] A recording tape such as a magnetic tape used as a data recording / reproducing medium (data backup) of a computer or the like is wound on a reel made of synthetic resin. Recording tape cassettes are known which house a reel of this type in a casing. The reel of this recording tape cassette may have a structure in which, for example, a hub on which a recording tape is wound on an outer peripheral surface, and an upper flange and a lower flange for holding ends in the width direction of the recording tape are respectively formed as separate bodies (three-piece structure) ) (see, for example, Japanese Published Patent Application (JP-A) No. 2007-335032). [0003] A ree...
