PURPOSE:To facilitate position aligning when an atmospheric senser is placed on an exhaust guide to reduce the aseembling time by fixing the atmospheric senser to the exhaust guide by a fixing metal fitting for nets. CONSTITUTION:A base 16 is positioned and fixed at two places by claws 19 and further constantly face-fitted and positioned rectangularly with the claws 19 by means of flanges 20 provided at two symmetrical positions in the net fixing metal fitting 17. The flanges 20 provided in the metal fitting 17 is made longer than or equal to the picth dimension at two places of cut-away traces 22 formed for making claws 19, and a clamping force of screws 23 at the cut-away traces 22 is transmitted through the flanges 20, and is delivered positively to the fitting part of a stepped hole A18 and a steppted hole B21. The dimensions of both the stepped hole A18 and the stepped hole B21 provided at the metal fitting 17 and the exhaust guide 7 are made equal, and hence an effect of improving airtightness when the atmospheric senser is fixed to the exhaust guide facilitation of the position alignment and improvement of workability can be achieved. |
