ABSTRACT:
The whole main tank for housing the constant temperature liquid the temperature of which is adjusted by a temperature adjusting device is supported in a sub tank with a gap as a heat insulating layer around the main tank. A liquid level regulating mechanism supplies and discharges the constant temperature liquid between inside of the main tank and the gap formed in the sub tank to thereby achieve heat insulation and regulation of the liquid level of the constant temperature liquid housed in the main tank by utilizing the same gap in the sub tank.
