Abstract
A step adjuster for an elliptical exercise device includes two assembly frames that are each pivotally connected with a sector gear and a movable sector disc for mutual movement. An eccentric portion of the sector gear and the movable sector disc are connected to crank blocks in slide grooves of the assembly frames by means of adjusting arms, and pedal cranks are respectively connected between the crank blocks and pedals. The sector gear has teeth engaging a worm gear of a hand crank, and moves to synchronously adjust the distance between the pedals and the connect rods.
