Horse-riding type exerciser

Abstract

A horse-riding type exerciser comprises a base, a support structure, a power system, a first spindle structure, a second spindle structure, a rocking means and a seat cushion. The power system can drive the first spindle structure and the second spindle structure for further allowing the multi-angular movement of the rocking means. The rocking means is further attached to the seat cushion. As a result, the multi-angular movement of the rocking means further enables the seat cushion to perform changeful movements.
