PROBLEM TO BE SOLVED: To provide a reel structure capable of suppressing change in the position of a flange in an axial direction due to deformation of a hub and improving position accuracy of the flange in the axial direction with respect to the hub.SOLUTION: A reel 10 comprises: a hub 12 having a plurality of through holes 30 formed in a coupling part 32 for coupling a cylindrical part 13 around which a recording tape is wound to a shaft center part 18; a first flange 14 which is provided in one end part of the hub 12 and includes a first inner peripheral part 15 coming in contact with a first reference surface 32C formed in the coupling part 32 and preventing a first flange surface 14A from coming in contact with the cylindrical part 13, and a first insert part 46 inserted into each through hole 30 of the coupling part 32; and a second flange 16 which is provided in the other end part of the hub 12 and includes a second inner peripheral part 17 coming in contact with a second reference surface 32D formed in the coupling part 32 and preventing a second flange surface 16A from coming in contact with the cylindrical part 13, and a second insert part 48 inserted into each through hole 30 of the coupling part 32 to be joined with the first insert part 46. |
