Abstract: PROBLEM TO BE SOLVED: To provide a sensor fitting unit incorporating a small fan unit which is structured in a manner that sensing operation of a sensing sensor may be performed properly and effectively so as to prevent the generation of uncomfortable noises when driving the small fan unit and to improve the controllability for an object to be controlled without failing safety and beauty of interior design, when the small fan unit is used. SOLUTION: This unit is provided with a suction port 22 and a discharging port 24 on its front side and a cover member 12 for sealing and engaging a casing 10 on its rear side, and a passage member 30 in which a sensing sensor 28a is fitted corresponding to the suction port 22 on the rear side of the member 12 is communicated, and further a small fan unit 32 is communicated with the outlet side of the member 30. Then a motor for driving the unit 32 is provided with a motor drive controlling circuit to eliminate or muffle noises generated by fan rotation.

Abstract: PROBLEM TO BE SOLVED: To obtain an indoor sensor mounting unit by which a sensor can be mounted simply by a method wherein a cylindrical casing in which a sensor mounting board is built is fixed to an indoor installation plate, a tip cover member is installed at its tip part and a rear cover member through which a wiring conductor is passed is installed at its rear end part. SOLUTION: Air-permeable tip cover member 16 is installed so as to be detachable at a flange part 12 at the tip part of a cylindrical casing 10 with a built-in sensor mounting board 18 on which various kinds of sensors are mounted. An air-permeable tip cover member 26 in which a through hole 22 used to guide a wiring conductor 20 connected to the board 18 and a ventilation hole 24 are made is installed so as to be detachable at the rear end part of the casing 10. An opening part is formed in an installation plate 30, a bracket 34 is brought into contact with the inside face of the plate 30, a ring-shaped fixation member 36 is brought into contact with the outside face of the plate 30, and they are coupled and fixed by setscrews 38. The flange part 12 at the casing 10 and the fixation member 36 at the plate 30 are brought into contact, they are twisted and coupled, and a mounting unit can be installed simply in a state that only the member 16 is exposed.
