Abstract
An engagement portion with a shape recessed in a radial direction of a sleeve is formed on an outer peripheral surface of the sleeve so as to circuit the outer periphery of the sleeve. The engagement portion is also disposed inside an assembly hole of a housing. Caulking of an area surrounding an opening of the assembly hole joins the engagement portion and a deformed portion of the housing. Parts such as sealing members and bushings become unnecessary, because the assembly hole and the sleeve are sealed by contacting surfaces of the deformed portion and the engagement portion. Furthermore, fixing of the sleeve and the housing, as well as the formation of a sealed portion between the assembly hole and the sleeve assures the realization of a one-time caulking process.
