Claims

[Scope of Claim for Utility Model Registration] (1) Tape between a clamp hole 10 provided at one location on the outer peripheral surface of the plastic hub 4 and a clamp piece 20 that is press-fitted into the clamp hole 10 from the radial direction. To clamp and fix the ends, a protrusion 11 is provided at the center of the inner bottom of the clamp hole 10, and protrusions 13, 13, which can be elastically deformed in the inner and outer directions, are extended in a cantilevered manner from both left and right sides of the protrusion 11. Piece 13,1
3 and the left and right side surfaces 1 of the clamp hole 10 facing thereto
4 and 14, and between the inner bottom of the clamp hole 10 and each protruding piece 13.
A gap 16 is formed in communication with the gap 15 to allow elastic deformation inward. Leg pieces 22, 22 that engage in the gaps 15, 15 are integrally protruded from the left and right ends, and the tip of each leg piece 22 has a clamp piece 20 in the state that the clamp piece 20 is completely fitted into the clamp hole 10. An engaging portion 23 that wraps around the gap 16 at the tip of the projecting piece 13 is provided in a protruding manner, and the engaging portion 2
3 and the outer surface plate 21, there is a recess 24 into which the tip of the protruding piece 13 is inserted in a tight manner, and the outer surface plate 21
A protruding part 2 for causing an ejecting pin on the molding die side of the clamp piece 20 to come into contact with the central part of the inner surface of the clamp piece 20.
5, and the protrusion 11 is provided with a recess 12 into which the protrusion 25 is fitted. (2) The amount of protrusion L ₁ of the protrusion 25 from the inner surface of the outer plate 21 is determined by the amount L 1 of the protrusion 25 from the inner surface of the outer plate 21 when the ejector pin on the molding die side of the clamp piece 20 is brought into contact with the portion where the protrusion 25 is present. The tape cartridge according to claim 1 of the utility model registration claim, which is sufficient to leave a margin space S.S of 0.1 mm or more. (3) The amount of protrusion L ₁ of the protrusion 25 from the inner surface of the outer plate 21 is the amount L 1 of the protrusion 25 from the protrusion end surface of the protrusion 25 .
Distance L to the line connecting the narrowest parts of 2 and 22 ₁ of 2
2. The tape cartridge according to claim 1 or 2 of the utility model registration claim, which is set to /2 or more.
