PURPOSE:To provide a rotary device having high assembling efficiency and production efficiency. CONSTITUTION:A unit roller 20 provided with a retainer 22, holding balls 21 and, holding holes 22a forming lug members for holding the balls 21 on its peripheral edge is arranged on the outer peripheral wall 1b of a base 1 and a cabinet provided with a cathode ray tube is supported on the wall 1b so as to be rotated. The rotational drive of a rotation spindle of a motor 32 is transmitted to the base 1 through gear unit 30 provided with a worm gear 33 fixed to the motor 32, a worm wheel 35b engaged with the gear 33 and large and small gears and the cabinet is rotated in the clockwise and counterclockwise directions by the forward and reverse direction of the motor 32. The gear 33 is set up to a forward angle capable of transmitting rotational force from the wheel 35b to the gear 33, rotational force applied from the external is transmitted to the gear 33 by the wheel 35b and the cabinet is rotated by rotating the rotational spindle of the motor 32. |
