The abovementioned housing support “a” is provided on its bottom end with three coaxial pulleys (“a6”, “a7” and “a8”), the housing support “a” is provided on another bottom end thereof with a pulley “a9”. These pulleys (“a6”-“a9”) are wound thereon with an expansion band “a10”; and by changing of a changing wheel “a11 ”, a steel rope “a12” is linked up with the rope pulley “a1”.
  • When a user pulls a handle, a pulling rope “a13” on the rope pulley “a1” can be pulled to render the fly wheel “a4” to generate wind resistance; while the elastic restoration of the expansion band “a10” as well as transmission of various members can restore the changing wheel “a11” to its original position. The above stated structure can only obtain its expected effect by combination of a plurality of pulleys and belt pulleys; because of too many members in assembling, not only the cost of manufacturing is increased, the volume after assembling is increased, but also the rate of damage in use is largely increased.
  • In view of this and to get rid of the above stated defects, the inventor of the present invention developed the structure of the present invention based on his experience of years and nonstop study and improvement, to make the elements required for assembling reduced, and also make the cost and space for storing reduced.
