Claims

[Scope of utility model registration request]

A magnetic cheap reel in which a hub and a lower flange are integrally formed, and an upper flange is attached to the free end of a knob, which consists of a plurality of protrusions of the same shape closely spaced with a small protrusion at the top. A columnar collective protrusion is provided protruding from the center of the free end of the hub, and the collective protrusion has a slit in which the gap between the protrusions is parallel to the reel rotation axis, and an upper portion of the outer circumferential surface of the collective protrusion faces toward the lower flange. The upper flange is formed with an inclined upper tapered surface that widens, and the outer peripheral side surface below the upper tapered surface is formed with an inclined lower tapered surface that narrows toward the lower flange, and the upper flange receives the collective protrusion. A magnetic tape reel comprising a hole in the center and can be assembled into one piece by pushing the collective protrusion into the hole.
