PROBLEM TO BE SOLVED: To provide a cooling device for cooling a machine tool or its similar machine, wherein it has a circulating circuit system having cooling medium circulated therein, the cooling medium is supplied to a temperature adjusting device for the machine tool, an amount adjusting device is arranged at the circulating circuit system, external cooling medium is adjusted in its amount and supplied to the cooling medium circulated in the circulating circuit system, a system having the amount adjusting devise capable of being controlled through the adjuster device is improved, and a continuous constant temperature level can be maintained within the temperature adjusting device by this cooling device. SOLUTION: A circulating circuit system 40 has a shock absorbing tank 22.2. A cooling medium is guided through the shock absorbing tank. An amount adjusting device 27 adjusts an amount of external cooling medium and supplies it into a returning circuit extending from a temperature adjusting device 27 and further adjusts its amount and supplies it into the circulating circuit system 40 before the shock absorbing tank 22.2.
