ROTARY FILLING DEVICE

PROBLEM TO BE SOLVED: To prevent abrasion by reducing a load applied on packing, and to keep tight seal effect of the packing for a long period of time.SOLUTION: To hold a lower surface side of a flange 92 formed at a PET bottle 90, a container holding part 100 includes: horizontal surfaces 135, 136; and inclined surfaces 133, 134 inclined so as to be gradually lowered toward the inside in a radial direction of a rotor. A swing guide 200 includes: a support part 202 for supporting the lower surface side of the flange 92 of the PET bottle 90 with the horizontal surfaces 135, 136; and an abutting part 203 for abutting on an upper surface side of the flange 92. By swinging the swing guide 200 downward and pushing the flange 92 against the inclined surfaces 133, 134 by the abutting part 203, a bottom part of the PET bottle 90 is inclined so that the inside in the radial direction of the rotor is lowered. In the inclined state, an upper end 91 of a mouth part of the PET bottle 90 is made to stick firmly to packing.
