PURPOSE:To promote the protection of a temperature detecting part and the improvement of sealing performance and work efficiency, by inserting a temperature detector through an O ring to a mounting seat, which is mounted to a part where a temperature is detected, and fixing a fixing member to the mounting seat from the upper of the temperature detector. CONSTITUTION:When a temperature detector 1 is mounted, after an O ring 18 is mounted being fitted to the periphery of a cylindrical part 3b of a metal case 3, the temperature detector 1 is inserted into a mounting seat 10 till a flange part 3c is adapted to a stepped part 10d. In this way, the metal case 3, which provides a builtin temperature sensor 2, discloses a bottom part 3d in the inside of a refrigerant pipe 20. While the O ring 18, which is compressed between the periphery of the cylindrical part 3b of the metal case 3 and the bottom part of an O ring groove 10c in the mounting seat 10, is housed in the O ring groove 10c. And a fixing member 15, which screws its external threaded part 15c to an internal threaded part 10e of the mounting seat 10 holding the flange part 3c of the metal case 3 between a pressing surface 15b of the fixing member 15 and the stepped part 10d of the mounting seat 10, fixes the temperature detector 1 to the mounting seat 10. |
