Zusammenfassung:PURPOSE:To detect very easily abnormality of supercharge pressure, by providing an actuator operating with a detecting means to detect abnormal high supercharge pressure and a urging means driving a throttle valve to the direction of closing. CONSTITUTION:There are provided a supercharger 4 in an intake passage 2 and an exhaust turbine 5 in an exhaust passage 3. If supercharge pressure abnormally rises high, the pressure overcomes a spring 18 in a diaphragm device 15, and a rod 17 is lifted to turn a lever 20 clockwise. If the lever 20 is turned, the lever is disengaged from a stopper part 24, and a connecting member 23 turns a throttle lever 28 clockwise by urging force of a return spring 27. In this way, depressing force of an accelerator pedal is increased, and the driver can very easily detect occurrence of abnormality of supercharge pressure.
