PURPOSE:To provide a swiveling device for driving rolling and pitching of a bodily sensitively movable game machine by a servo motor. CONSTITUTION:Operating rods 1, 21 in both sides of a swivel base are connected with one end to the swivel base and the other end to output shafts 16, 26 of reduction gears 15, 25 through crank arms 17, 27, and the above-mentioned output shafts are driven by servo motors 13, 23 to provide brake devices 14, 24 for holding the output shaft braked in a condition of no excitation of the servo motors. A hydraulic device is eliminated by motor driving and also providing a holding plate 31, having a holding pin 30 with an axial center line agreeing with a rolling axial line A in one of a base and the swivel base and having a long hole 32 in the rolling direction slidably fitting the holding pin to the other, to prevent looseness of the swivel base. |
