    Abstract: An elliptical stepper includes a base, a damping device mounted on the base, two crank devices respectively laterally mounted to two opposite sides of the damping device. Each crank device has a stepping device mounted thereon and each stepping device has a roller set mounted to a bottom thereof, wherein the roller set is universally rolled relative to a corresponding one of the two stepping device. The base includes two opposite sides each having a guiding structure disposed thereon. Each guiding structure includes at least one rail having a front end outwardly extending relative to a center line of the base. Each roller set is moved along a corresponding one of the two guiding structures such that each stepping device provides a wiggling effect when moved along an elliptical route.
