Claims

[Scope of utility model registration request]

An upper rotating ring that rotatably supports the upper ends of a large number of curved members through a large number of link means provided at positions equally dividing the plane of the ring body; The upright support rotatably supports the lower rotating ring, which is integrally provided opposite to the upper rotating ring at a constant interval, and the lower ends of multiple curved members, and also supports the lower rotating ring. a lower support ring that is suspended so that the rings can rotate relative to each other; and a number of members that have a certain curved shape, the upper ends of which are rotatable to the upper rotation ring via ring means. The lower end is rotatably supported by the lower support ring, and the envelope circle formed by the outer peripheries of the multiple pieces at a constant horizontal position approximately midway between the upper and lower rotary rings is true with respect to the center of the device. An inflation bubble that forms a circle and whose diameter is changed by the relative rotation of the lower support ring and the rotary ring, and which matures while vertically contacting in the envelope circle, is kept at a constant diameter. A variable sizing ring in a thermoplastic synthetic resin cylindrical film manufacturing apparatus having a supporting curved member and a rotating means for driving the lower rotating ring to rotate the lower rotating ring relative to the lower supporting ring.
