摘要： A gas detecting device principally used for detecting liquor contained in expired gas of a driver of a car. The gas detecting device is of the type wherein an inlet opening for sucking expired gas of an object person for measurement is provided adjacent an end of a cylindrical member, and an air blower for attracting the expired gas thus sucked and a gas detecting element for detecting liquor in the expired gas are contained in said cylindrical member, and comprises an illuminating section connected to said power source for illuminating forwardly of said inlet opening of said cylindrical member. Thus, the gas detecting device is integrally provided with an illuminating function and a gas detecting function. The device may further comprise a convex lens located forwardly of the illuminating section for condensing light irradiated from the illuminating section whereby it is provided with a distance setting function for setting a distance between the object person for measurement and the gas detecting device in addition to the aforementioned two functions. The device may further comprise a switch having a movable contact connected to the power source, a first fixed contact connected to a light source of the distance setting section, and a second fixed contact connected to a heater contained in the detecting element whereby power consumption can be saved.
