...Valve room. Correction 1984. 9.14 The claims for utility model registration and the brief description of the drawings are amended as follows. O Utility Model Registration Claims In a device in which a check mechanism and a pressure regulating mechanism are adjacent to each other and a valve chamber A is formed between the two mechanisms, a pore 21 is formed in the valve chamber A below the check valve disc 12. A pressure reducing valve for water supply, in which a plug body 22 having a through hole 24 communicating with this pore 21 is airtightly attached to a valve box 3. BRIEF DESCRIPTION OF THE DRAWINGS The drawings show embodiments of the present invention; FIG. 1 is a vertical sectional side view of the main parts of a conventional pressure reducing valve, FIG. 2 is a vertically mounted side view, and FIG. 3 is a side view of a horizontally mounted type; Fig. 4 is a vertical sectional side view of the main parts of the pressure reducing valve of the present invention, Fig. 5 is a plan view thereof, Fig. 6 is an overall side view taken longitudinally from the other direction of the plug attachment part, and Fig. 7 is the main part of the valve box. FIG. 8 is an enlarged partial sectional view of the vicinity of the stopper. [Explanation of symbols], a... Drain plug, b... Valve spring retainer cover, C... Check valve rod, d... Check valve disc,
