Abstract: A Running exerciser structure including a base seat, a frame body and two rocking arms. Two support stems respectively upward extend from two sides of the base seat. Two vertical slide rails are respectively disposed on the support stems. Two sides of the frame body are respectively disposed with two rollers which can vertically roll along the slide rails. Two rocking arms are respectively pivotally disposed on two sides of the frame body and interconnected by a shaft. Two ends of the shaft are respectively disposed with two rollers. A telescopic rod is pivotally disposed between the frame body and the shaft. When a second motor drives the telescopic rod to extend, the rocking arms are driven to swing to elevate or lower the frame body. When the frame body is lifted, the rocking arms, telescopic rod and the frame body form a firm triangular supporting structure for stably supporting the running exerciser.
