Abstract

When an exhaust gas sensor (11) is mounted to an exhaust pipe (9) into which exhaust gas from an engine (7) is introduced, an intermediate member (24) is made to intervene between the exhaust gas sensor (11) and a boss (16) provided in an exhaust manifold (9), the intermediate member (24) being fastened to the boss (16) by bolts (29) and the exhaust gas sensor (11) being screwed into a screw hole (26) formed in the intermediate member (24), so that a sensor portion (12) at a front end of the exhaust gas sensor (11) is inserted into the inside of the exhaust pipe (9) . Though the screw hole (26) formed in the intermediate member (24) is to be exposed to high-temperature gas of the exhaust manifold (9), stainless steel, whose high-temperature strength is high, being used for the intermediate member (24), a female screw of the screw hole (26) is hard to be softened and an occurrence of torque down can be suppressed.
