PROBLEM TO BE SOLVED: To improve a vibration control performance of a temperature type expansion valve.SOLUTION: A temperature type expansion valve has a valve chamber in a valve main body, and is provided with a valve body arranged in the valve chamber. An operation rod 60 for operating the valve body is inserted in a through hole 70 of the valve main body, and driven by a power element. A vibration control member 100 is inserted in a vibration control member insertion hole 72. The vibration control member 100 has two stages of three vibration control springs, and supports the operation rod by a spring force. A vibration control performance is further improved by the spring force of the two stages of the vibration control springs at three parts. |
