CONSTITUTION: A turntable comprises a bearing housing, a base(10), multiple rollers, a rotary cylinder, a supporting board(30), and a shaft. The bearing housing including the bearing is formed in the base. The multiple rollers are formed around the bearing housing to be radially arranged. The rotary cylinder is fixed in the edge of the base. The supporting board is formed into a plate shaped structure. The shaft of the supporting board is assembled to the bearing of the base and a rod of the rotary cylinder is fixed at the bottom of the supporting board. The supporting board horizontally rotates around the shaft with the operation of the rotary cylinder.
