レツシヤレギユレータ。 a diaphragm separating a pressure chamber provided with a control port open to the low pressure side and an input port connected to the high pressure side from a negative pressure chamber provided with a negative pressure port guiding negative pressure of an intake passage of the engine; a valve body mounted on the diaphragm facing the control port to open and close the port; and a spring that elastically biases the diaphragm in a direction of contraction of the pressure chamber to close the valve body, In a pressure regulator for an internal combustion engine in which fluid pressure on the high pressure side is maintained at a predetermined pressure by a port, a negative pressure introduction pipe connected to the negative pressure port is extended to a position near the diaphragm in the negative pressure chamber. A pressure regulator for an internal combustion engine, characterized in that the pressure regulator functions as a stopper for regulating the movement of the diaphragm in the pressure chamber expansion direction.
