載の減圧弁。[Claims for Utility Model Registration] (1) The fluid flowing into the primary flow path is depressurized and flows out into the secondary flow path, and the fluid flows only in the direction from the secondary flow path to the primary flow path. A pressure reducing valve having a check valve structure for allowing fluid to pass through, the check valve structure being composed of a deformable valve body having a slit at one end of a flow path formed inside an elastic body, and the slit comprising: When fluid pressure is applied in the direction from the secondary flow path to the primary flow path, the flow path is expanded and the flow path is in a communicating state, and when fluid pressure is applied in the opposite direction, the flow path is expanded. 1. A pressure reducing valve characterized by having a structure that is deformed back in a direction to block a passage. (2) The pressure reducing valve according to claim 1, wherein the deformable valve body is made of rubber.
