Abstract

An arrangement for sealing a housing with a cover that includes a central hole for holding a gasket for a shaft extending through the gasket in the installed state, and at least first and second hollow-cylindrical protuberances which project roughly in the direction of the shaft relative to the areas of the cover which directly surrounds them. The protuberances are inserted into the corresponding cavities of the housing. The peripheral surfaces of the first protuberance and its respective cavity adjoin one another essentially without play, and the second protuberance can be essentially freely positioned within its cavity in the direction of a line which connects the two center points of the two protuberances, with the second protuberance adjoining at least one point of the peripheral surface of the cavity in the direction of the cavity diameter which is perpendicular to the line.
