Abstract
In order to achieve seal durability and bring about a damping action for a piston-type pressure regulating valve, a pressure regulating valve of the present invention is characterized by a valve moving member moving in such a manner as to cause communication or block communication between a primary chamber and a secondary chamber within a case, wherein a plurality of central members are arranged between the case and the valve moving member and the plurality of central members are taken to be different materials. It is then possible to bring about both a damping action and seal durability using the central members by providing central members of different materials.
