Holding convex piece and the other flange plate A second holding convex piece which is formed by cutting and raising in the direction of the first holding convex piece to prevent rotation of the first holding convex piece by contacting the end face in the circumferential direction, and the other flange plate. And a third holding convex piece for preventing rotation of the first holding convex piece by coming into contact with the radial end surface of the first holding convex piece, It has the following effect.

The two flange plates are in a compact state in which the plate surfaces are in close contact with each other, and when the connecting portion is erected from the state along the flange plates, the flange plates are separated from each other by a predetermined distance. The two flange plates are arranged substantially coaxially and at a predetermined distance from each other, and a strip-shaped tape member can be wound substantially coaxially with the flange plates between the plate surfaces of these flange plates.

Further, the connecting portion has a first connecting convex piece formed by cutting and raising one flange plate in the circumferential direction and a first connecting convex piece when the other flange plate is seen from the outside. Since the connecting convex pieces formed by cutting and raising in the same direction as the cutting and raising direction are adhered to each other, the yield and the assemblability of the paper of the material can be improved, and the cost can be reduced and The connecting convex piece and the other connecting convex piece are adhered to increase the paper thickness, and when the tape member is wrapped around these connecting convex pieces, the connecting convex piece is prevented from buckling and bending, and the tape member Can be wrapped around cleanly and reliably.

Further, the holding portion is formed by cutting and raising one flange plate in the radial direction to form a first holding convex piece, and cutting and raising the other flange plate in the circumferential direction.
Is formed by cutting and raising a second holding convex piece which comes into contact with the end surface in the circumferential direction of the holding convex piece to prevent the rotation of the first holding convex piece, and the other flange plate in the circumferential direction. And a third holding convex piece for preventing rotation of the first holding convex piece by contacting the radial end surface of the holding convex piece of No. 3, the holding section is cut and raised integrally with the flange plate. It can be configured with the first to third holding convex pieces, and it is not necessary to separately prepare another connecting member to connect the flange plates to each other, which improves the yield and assemblability of the paper of the material, and reduces the cost. In addition, since it is made of paper, it can be discarded together with other combustible wastes, and the disposal work can be easily performed.

Further, the holding portion is formed by cutting and raising a first holding convex piece formed by cutting and raising one flange plate in the radial direction, and cutting and raising the other flange plate in the circumferential direction.
Is formed by cutting and raising a second holding convex piece which comes into contact with the end surface in the circumferential direction of the holding convex piece to prevent the rotation of the first holding convex piece, and the other flange plate in the circumferential direction. And a third holding convex piece that comes into contact with the radial end surface of the holding convex piece to block the rotation of the first holding convex piece. Therefore, the flange is formed by raising the first holding convex piece. The plate can be held at a predetermined distance, and the second holding convex piece and the third holding convex piece can be held.
By erecting the holding convex pieces, it is possible to prevent the first holding convex pieces from rotating, and thus it is possible to ensure the separation of the flange plate by the connecting portion.
