型パイロット弁。a housing having a high-pressure side flow path, a low-pressure side flow path, and an output port; a spool provided in the housing for switching the output port between the high-pressure side flow path and the low-pressure side flow path; and a spool that engages with the spool. and a button for slidingly displacing the spool, and by pressing the button, the spool is slid to reduce the liquid pressure from the high pressure side flow path and supply it to the output port. The pressure reducing valve type pilot valve includes an operating rod that is automatically supported by the housing and a cam member that presses the button according to rotation of the operating rod, and the cam member is fixed to the operating rod. The mounting bracket is provided with an adjusting screw that can be screwed in and out of the mounting bracket and is installed obliquely with respect to the axis of the operating rod, so that the amount of play can be adjusted according to the screwing in and out of the adjusting screw. A pressure reducing valve type pilot valve characterized by:
