PROBLEM TO BE SOLVED: To attain ease of the installation work of a supervisory device by integrating a plurality of kinds of sensors resulting in improving an outward appearance of a bath room and prevent the internal sensors from being deteriorated due to intrusion of moisture and water contents. SOLUTION: A sealing projection 31 is formed to an entire circumference of an inner side of a sensor section 5 in which an artificial retina sensor 10 and an infrared ray sensor are placed. A groove 50 is placed to the entire circumference of an opening of a sensor container chamber 36 in which the artificial retina sensor 10 and the infrared ray sensor of the sensor section 5 are contained, a rubber packing 51 is place in the groove 50. A sensor base 8 covers the opening of the sensor container chamber 36 to contain the artificial retina sensor 10 or the like in the sensor container chamber 36, the sensor section 5 is screw-fastened to the sensor container chamber 36, a sealing projection 31 of the sensor section 5 is pressed into contact with the rubber packing 51 to air-tightly seal the opening of the sensor container chamber 36 and the sensor section 5. |
