弁における先立弁。 In a pressure reducing valve that controls the opening and closing of a valve port that communicates between a primary pressure chamber and a secondary pressure chamber via a diaphragm that is displaced in response to pressure fluctuations in the secondary pressure chamber, a spherical pilot valve body is provided at the lower end. The pilot valve stem, which is fixedly attached, is slidably inserted into the valve guide, and a spring is press-fitted between the inside of the lower end of the cap and the pilot valve body, thereby integrating the valve guide and the cap. A pilot valve in a pressure reducing valve characterized by:
