In conventional devices, a helical tube or a flexible tube is used as the jacket tube, but since the helical tube is generally thin and complicated in shape, it is difficult to connect it with an intermediate connecting fitting or the like. Also, spiral tube,
Due to the structure of flexible tubes, there is little play in the axial direction of the tube, and the minimum bending radius when inserting and withdrawing a test object such as a heater is approximately determined by this amount of play. For curved pipes having many routes, there have been problems such as blockage of the pipe by a heater or the like, buckling of the mantle tube, and occurrence of plastic deformation during insertion and withdrawal. Furthermore, since the flexible tube is airtight, there is no problem in the parts that come into contact with the secret mechanism, but when a heating element such as a micro heater is built in, the heat transfer to the outside of the jacket tube is difficult. There was a problem in that the heat transfer efficiency of the built-in heating element was reduced due to obstruction by the gas in the annulus.

The thickness, width, and winding pitch of the band are selected, and the edges of the band are rounded to enhance insertion and withdrawal properties when bent. In addition, since the core metal 5 needs to function as a strength member without reducing insertion/extraction properties, stranded SUS wire is used, and the intermediate support metal 2 that connects the steel strip members 1 is used for the core metal 5. In this section, cap 8 is attached to the end of the same stranded wire.
The cap 8 and the intermediate support fitting 2 are fixed by TIG welding 10.
