Temperature sensing tube for expansion valve

To provide a temperature sensing tube for an expansion valve in which a hunting can be prevented by slowing of a temperature reaction rate of an expansion valve, a ceramic sintered member serving as a heat transfer delay member in a temperature sensing tube is fixed so as not to directly contact with a tubular member by fixing springs provided at both end portions, whereby a heat transfer from the tubular member to the ceramic sintered member becomes slow, temperature is not transferred from a mated piping directly via the tubular member, whichever outer surface of the temperature sensing tube contacts with the piping, and a reaction rate with respect to a temperature rise of the expansion valve can be made slow.
