The thermal deformations (thermal expansions and contractions) of a rib 105, a nipple nut 106 and a boss portion 201 are made substantially the same by making the coefficients of linear thermal expansion thereof substantially the same. According to the construction, even if an exhaust gas temperature sensor 100 is disposed in the vicinity of an exhaust manifold whereby the thermal deformations (thermal expansions and contractions) of the rib 105, the nipple nut 106 and the boss portion 201 are large, since the rib 105, the nipple nut 106 and the boss portion 201 are thermally expanded and/or contracted substantially all together, the loosening of threads due to a hot-cold cycle can be prevented. <IMAGE> |
