Claim:
A reel comprising: a hub that is formed of resin and that has a cylindrical tube portion on whose outer peripheral surface a recording tape is wound, an extending portion that extends from an inner peripheral edge of a lower end portion of the cylindrical tube portion toward a radial direction inner side, and an abutting portion provided at the extending portion; an upper flange that is provided integrally so as to extend from an outer peripheral edge of an upper end portion of the cylindrical tube portion toward a radial direction outer side; a lower flange that is formed of resin, and that is provided at the radial direction outer side of an outer peripheral edge of the lower end portion of the cylindrical tube portion so as to face the upper flange; and a floor wall that is provided integrally at the radial direction inner side of the lower flange, and that has a position restricting portion that restricts a radial direction position of the abutting portion from the radial direction inner side, and a region of the floor wall, which region is between the cylindrical tube portion and the position restricting portion, is welded to the extending portion; wherein the cylindrical tube portion of the hub can freely deform toward the radial direction inner side of the hub, at the radial direction outer side of the welded region.
