<P>PROBLEM TO BE SOLVED: To provide a gas analyzing apparatus which can inhibit damages due to heat from the base end section of a gas sensor that is an outlet for lead wire, without increasing the part cost. <P>SOLUTION: In this apparatus, a connecting pipe 61 is inserted into a support tube 21 inserted and secured into a flue so as to accommodate at least the base end section of the gas sensor 41 fixed on an end wall 31 of the support tube 21 within the connecting pipe 61, and to introduce cooling air, from the base end side of the connecting pipe 61. That is, an air-supply pipe 56 is inserted into the connecting pipe 61 so as to direct a nozzle section 56a, that is the nose aperture of that air-supply pipe, toward the base end section of the gas sensor 41. By supplying the base end section of the gas sensor 41 with cooling air, a lead wire pressing member 47 loaded on the base end section is cooled. Thus, rise in the temperature of the lead wire pressing member 47 is inhibited, and damages due to the heat of the lead wire pressing member 47 can be avoided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
