Abstract
The invention relates to a treading exercise apparatus that includes a crank and a base. The crank is constructed as a first shaft in the middle thereof on which a bearing, a bushing and a resistance flywheel are received so that the crank rotates on a middle post of the base. Meanwhile, both sides of the first shaft are constructed as a correspondingly symmetric U-shaped treadle rod relative to the shaft which a treadle pad is rotatably received for treading movement in alternating succession. The outer side of each of the treadle rods is constructed as a second shaft. The second shafts and the first shaft are coaxially disposed along a horizontal axle line L. Moreover, the second shafts extend through side posts of the base respectively and are rotatably mounted thereon. Since the unbalanced force created by the treading movement on the crank is effectively supported, a stable treading movement can be achieved. Meanwhile, the related components can be well protected from damage, thereby elongating the service life thereof.
