Abstract

A footrest ring tightening structure is disclosed, in which a central tube utilized for supporting a seat is assembled with a footrest ring at a predetermined height. In the footrest ring tightening structure, at least two or more clamping members are covered along an outer periphery of the central tube at the predetermined height, so that a middle sleeve of the footrest ring which is integrally formed with a predetermined wide spoke is allowed to be mounted on the outer peripheries of the clamping members. Further, with a fixing ring comprising an inner-peripherally extended protrusion part utilized to access to a space that is concave-arranged on an upper end of the clamping member, each clamping member covered on the outer periphery of the central tube can be exactly inwardly-squeezed and abutted, so that the footrest ring can be kept with a stable clamping and positioning with respect to a layer surface of the central tube after being assembled.
