<p>PURPOSE:To provide a photosensor housing structure of a detecting device capable of reducing the number of parts to simplify the structure, and preventing the fracture of a sensor housing case. CONSTITUTION:A housing cylinder section 24 is provided at a part of a housing case 1 and a bottomed cylindrical sensor housing case 26 made of an insulation material is inserted in the section 24. A flange 43 formed at the open end of the case 26 is coupled to an engagement step section 45 formed at the open edge of the section 24. Furthermore, a sealing ring 29 is laid between the internal surface of the section 24 and a mounting cylinder section 41. A photosensor 27 is, then, laid within the case 26 and an optical fiber cable 35 connected to the sensor 27 is led out through a connecting fixture 30. In addition, the case 26 is filled with an insulator 36 for sealing the sensor 27.</p> |
