ヤレギユレータ。 A housing disposed in the fuel supply passage, a diaphragm separating the inside of the housing into a negative pressure chamber and a fuel chamber, a return passage whose tip opening is disposed in the fuel chamber, and a holder attached to the diaphragm. A pressure regulator comprising: a valve body that is provided and opens and closes an opening of the return passage; and an elastic member that is disposed in the negative pressure chamber and always biases the valve body in a closing direction. A pressure regulator characterized in that at least one of the components is made of a shape memory alloy material that expands or contracts when the engine is at high temperature to increase the biasing force of the elastic member.
