Claims

[Claims for Utility Model Registration] 1. A tape winding body 1 in which a tape 3 is wound around a pipe-shaped core body 2 is rotatably supported by a pair of supports 4 that are engaged with both ends of the core body 2. In the rotational support device, a pair of supports 4 are arranged coaxially and so as to be able to approach and separate from each other in the axial direction, and each support 4 has a rotatable support main body 6 and an outer peripheral portion thereof. The support piece 7 includes a support surface 7a that comes into contact with the inner circumferential surface of the core body 2, and an abutment surface that comes into contact with the outer end surface of the core body 2. 7b, and when the abutment surface 7b abuts against the outer end surface of the core body 2 and is relatively displaced in the axial direction, the support surface 7a can be displaced radially outward. To,
The support body 6 is movably equipped with a support piece 7, and the support piece 7 is biased by a spring 12 to move in a direction in which the support surface 7a moves toward and away from the center in the radial direction, so that the support piece 7 is in a free state. The following is a rotational support device for a tape wound body, characterized in that each support surface 7a of the 7 groups of support pieces is recessed inside the inner diameter of the core body 2. 2. The rotation support device for a tape roll according to claim 1, wherein the support piece 7 is supported so as to be slidable in the axial direction and in the radial direction with respect to the support main body 6.
