Abstract
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 tubecontacts with the piping, and a reaction rate with respect to a temperature rise of the expansion valve can be made slow.
