摘要： A pressure regulating valve includes a casing, a holder, a fixed valve, a movable valve, a spring member, a diaphragm, and a filter. The filter is configured to filter fluid flowing from a flow inlet of the casing into a pressure chamber. The filter includes a filtering part for filtering fluid and a holding part including a frame part for holding an outer periphery of the filtering part. An alignment structure configured to align the holding part at a predetermined position is provided between the holding part of the filter and the holder, or between the holding part of the filter and the casing.
