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.
