THERMOMETER FITTING STRUCTURE, AND HEATING CYLINDER HAVING THE STRUCTURE

PROBLEM TO BE SOLVED: To provide a thermometer fitting structure capable of more easily fitting a thermometer to an object to be measured such as a cylinder body without loss of accuracy of a measured temperature.SOLUTION: A thermometer fitting structure 18 has a non-penetration hole 22, female screw hole 23, and male screw 24. The non-penetration hole 22 has an aperture 22a arranged on an outer surface 16a of an object to be measured 16. A thermometer is inserted into the non-penetration hole 22 through the aperture 22a. The female screw hole 23 penetrates between an outer surface 16a and a side face 22b of the non-penetration hole 22. The male screw 24 is threaded into the female screw hole 23. And the female screw hole 23 and the male screw 24 extend in a direction D inclined to a side opposite to a bottom 22d of the non-penetration hole 22 relative to a side face part 22c facing a tip of the male screw 24, out of a side face 22b of the non-penetration hole 22.
