US Patent 7785234 Rocking type exercising apparatus

A rocking type exercising apparatus includes a movable unit on which a user rides and a driving unit for causing the movable unit to perform a rocking motion. The driving unit includes a pitch driving part for causing the movable unit to rock in a forward/backward direction, a roll driving part for causing the movable unit to rock in a leftward/rightward direction and a yaw driving part for causing the movable unit to rotate about a vertical axis. When the movable unit is moved forward by the pitch driving part and is tilted to either the left or the right by the roll driving part, the yaw driving part rotates the movable unit in the same direction as the tilted direction of the movable unit.
