Abstract
A pedal structure mainly including a pair of bases each having a facing-inward long recess with toothed side walls, a pair of adjusting supports each including an upper shaft holder portion for receiving one end of a shaft and a lower coupling rod portion having toothed side walls for engaging with the long recess of the base, and a pair of pedals pivotally rotatably assembled to the shaft extending between the two shaft holder portions of the adjusting supports. The pedal structure is characterized in that a massage ball is rotatably mounted at a central point of the shaft, that the adjusting supports may be adjusted in height by engaging their toothed side walls with the toothed side walls of the long recesses at different levels so that the pedal structure can be comfortably used by different users even they have different leg lengths or sit in chair of different heights, that the two pedals can be either locked together to move synchronously or not locked to move independently, and that the two pedals can be locked in any suitably inclined position without being rotated about the shaft.
