FIGS. 1 , 2, 3, and 6, when thedriving wheel 51 is moved to the second position by theactuation member 52 through operation of thecontrol device 53, thefirst engagement portion 513 of thedriving wheel 51 disengages from thefirst coupling portion 313 of thenon-automatic mechanism 3. Thesecond pegs 5141 of thesecond engagement portion 514 of thedriving wheel 51 engage with the second coupling holes 434 of thesecond coupling portion 433 of theautomatic mechanism 4. Thus, the pedal exerciser is in an automatic mode, and theshaft 2 can driven by themotor 411 of thepower source 41 through transmission by thefourth wheel 42, thesecond belt 44, thethird wheel 43, and thedriving wheel 51. The user can place his hands or legs on thepedal rods 21 and driven by thepedal rods 21, providing a force-saving effect as well as a rehabilitating effect. - In view of the foregoing, the pedal exerciser provides both of automatic and non-automatic modes, providing enhanced utility while allowing easy operation. The pedal exerciser does not have to include the damping
device 34. Furthermore, thethird wheel 43 can be directly driven by thepower source 41 without using thefourth wheel 42. Further, theactuation member 52 can be manually operated. - Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the essence of the invention. The scope of the invention is limited by the accompanying claims.
