Claims

[Claims for Utility Model Registration] (1) The small-diameter stepped portion of the central shaft 2, which is fixed to the center of the rotary table 1 and has a small-diameter stepped portion at the bottom, is rotatably inserted into the water supply pipe 4. , a vertical temperature-controlled water flow path provided in the water supply pipe from the temperature controller, a horizontal temperature-controlled water flow path connecting the water supply pipe and the central axis, and a vertical temperature-controlled water flow path in the center axis. A temperature-controlled water supply mechanism to a rotary table mechanism, characterized in that temperature-controlled water can be supplied to a cavity. (2) The temperature-controlled water supply mechanism to a rotary table mechanism according to claim (1), wherein the central axis is a cylinder, and the cylinder is rotatably inserted into a large-diameter water supply pipe.
