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.
