Abstract
There is disclosed a method of manufacturing, in which a diaphragm not provided with an annular rib is fastened to a housing through a spring casing. The method of manufacturing comprises: a process, in which supports of a supporting slider rested on a floating block through a supporting spring, which is mounted in a receiving chamber of a lower die are made to extend through fluid passing holes of the housing, and the housing is rested on the supporting slider; a process, in which a spring casing is set in a receiving cavity of an upper punch vertically movably disposed at a position upwardly of the lower die, with an end portion of an opening of the spring casing being opposed to the housing; a process, in which the upper is approachingly moved toward the lower die, whereby the diaphragm is pressed through a coil spring for regulating pressure which is assembled in the spring casing so that the outer peripheral portion of the diaphragm is brought into contact with the flange of the housing; and a process, in which the downward movement of the upper punch toward the lower die is continued, whereby the end portion of the opening of the spring casing is bent to an end face of the ho…
