る燃料圧力調整装置。 Fuel pressure supplied to a fuel injection valve that injects fuel into an intake passage of an internal combustion engine is controlled so that the pressure difference becomes a set pressure by a relief valve that responds to a pressure difference between the fuel pressure and the pressure inside the intake passage. In the fuel pressure regulating device, a shape memory alloy spring is provided whose spring constant changes to increase the opening pressure of the relief valve when the fuel temperature exceeds a predetermined value, so as to increase the set pressure. A fuel pressure regulating device characterized by:
