PROBLEM TO BE SOLVED: To solve a problem in which a component deforms or is damaged owing to compressive stress generated due to a difference in coefficient of linear expansion between components in high-temperature environment, in a housing structure wherein structure components made of a plurality of materials, such as resin, metal, etc., differing in coefficient of linear expansion are clamped together with screws. SOLUTION: Contact surfaces of a resin component 1 and a metal component 6 are not right-angled with a clamping component, and then, when they are clamped together, pretension is applied to the resin component in a drawing direction to cancel the compressive stress applied to the component of resin etc., having a high coefficient of linear expansion in high-temperature environment. The contact surfaces are finished into mirror surfaces or coated with lubricants to reduce a coefficient of friction, thereby reducing the compressive stress. COPYRIGHT: (C)2005,JPO&NCIPI
