摘要： PROBLEM TO BE SOLVED: To downsize a device by attachably and detachably mounting a gas sensor on a sampling head by lever operation. SOLUTION: A lever 9 has a pressing piece having a substantially V-shaped part having one end provided on a base in such a manner as to be rotatable and rockable and the other end extended to a sensor mounting port 17, and also having an apex on the rotation terminal point side on a gas sensor 8 side. A back plate 11 is elastically pressed to the back surface of the pressing piece by the pressing force of the degree to which the gas inlet port of the gas sensor 8 is fitted to the sensor mounting port 17. A height regulating base 13 positions the gas inlet port 18 to the height opposed to the gas mounting port of a sampling head 7. The gas sensor 8 can be pressed and fixed to the sensor mounting port 17 of the sampling head 7 by a simple operation of setting the gas sensor 8 in a rough position and pressing down the lever 9. The fixation with the sampling head 7 can be released by pulling up the lever 9.
