A support ring for holding a fabric seat on an inclined frame tube of a portable chair frame allows the support ring to rest horizontally on the inclined frame tube so as to enable the fabric seat also resting horizontally on the chair frame. The support ring has a supporting hole contributed by two semi-circular portions and an intermediate portion extended between the two semi-circular portions. Each of the semi-circular portions has a diameter equal to or slightly larger than a diameter of the inclined frame tube. The intermediate portion also has a width equal to the diameter of the semi-circular portion. When the inclined frame tube fittingly passes through the supporting hole and is supported inclinedly with the horizontal, the support ring can be horizontally mounted on the inclined frame tube while a lower half of the frame tube resting on an upper edge of one of the semi-circular portion of the supporting hole and an upper half of the frame tube supporting by a lower edge of the another semi-circular portion of the supporting hole. Therefore, the fabric seat can be mounted horizontally on the chair frame and the downwardly force applied on the fabric seat can be evenly distributed and supported around the support ring.

[ What is claimed is:] [10.]10. A support ring mounted on a corner portion of a fabric seat wherein an inclined frame tube is arranged to be inclined with respect to said fabric seat for holding said fabric seat on said inclined frame tube, said support ring having a supporting hole contributed by two semi-circular portions and an intermediate portion extended between said two semi-circular portions, each of said semi-circular portions having a diameter at least equal to a diameter of said inclined frame tube, said intermediate portion also having a width at least equal to said diameter of said semi-circular portion, wherein when said inclined frame tube fittingly passes through said supporting hole and is supported inclinedly with respect to horizontal, said support ring is horizontally held on said inclined frame tube while a lower half of said frame tube resting on an upper edge of one of said semi-circular portion of said supporting hole and an upper half of said frame tube supporting below a lower edge of another said semi-circular portion of said supporting hole.
