PROBLEM TO BE SOLVED: To provide an assembly capable of restraining preload omission or the like when the temperature rises without interposing many shims or the like. SOLUTION: In this assembly consisting of a casing 1 and an interior part 2 different from each other in thermal expansion coefficient respectively, a restricting member 3 for restricting the transformation of one with higher thermal expansion coefficient (the casing 1 is composed of a member with higher thermal expansion coefficient in the example shown in the figure.) is set. The transformation difference between the casing 1 and the interior part 2 can be effectively restrained by restricting the transformation of one with high thermal expansion coefficient (the casing 1) especially by a stepped part 3C and a nut 6 of the restricting member 3 even if transformation difference by thermal deformation resulting from temperature change between materials which compose the assembly and are different from each other in thermal expansion coefficient respectively occurs. The preload omission or the like in a taper bearing pivotally supporting the interior part 2 is effectively prevented by maintaining the relatively positional relationship in design between the casing 1 and the interior part 2 regularly.
