Abstract
A capsule type filter assembly provides increased strength by fixing ends caps of a filter element to a housing at both ends. At one end, a tubular part extends through a hole in the housing and is joined to the housing. An inner space of the tubular part communicates with the inner space of the filter element. In this configuration, the structural strength of the filter housing is enhanced by making the integrated body of the end caps and the filter element function as the reinforcing means for the housing.
