Abstract
A proportioning valve of the present invention has a columnar portion protruding at the head of a retainer for slidably retaining a plunger. The outside diameter of columnar portion is set in such a manner that when a retaining ring, which inhibits the movement of the retainer in one direction, is completely set into an annular groove in a valve housing, the retaining ring is positioned around the columnar portion, and when the retaining ring gets out of the annular groove, the retaining ring is positioned at the end of columnar portion. A stopper for the plunger is disposed on the retainer so that a valve element cannot abut against a valve seat when the retainer is located at a position shifting in the output pressure direction.
