ABSTRACT:
A housing having an inner part radially inside of an outer part so as to form a hollow space therebetween. The outer part has two opposite end portions which radially extend inward toward the inner part so as to further define the hollow space. The end portions and the inner part form interengaging projections and grooves. The inner and outer parts are composed of different materials with different heat expansion coefficients. The interengaging projections and grooves are thermally expanded against each other to effect a moisture-tight sealing of the hollow space.
