ル弁開度制御装置。a first negative pressure operating chamber that selectively introduces intake pipe negative pressure via a first negative pressure delay valve according to a predetermined touch opening position of the throttle valve; and a touch valve closing side of the touch opening position. A second negative pressure working chamber selectively introduces intake pipe negative pressure via a second negative pressure delay valve according to the opening position, and is actuated by the first negative pressure working chamber to open the throttle valve. A two-stage diaphragm throttle positioner having a first actuating rod for controlling the position of the first actuating rod and a second actuating rod actuated by a second negative pressure working chamber to additionally control the position of the first actuating rod. In a throttle valve opening control device for a two-wheel drive/four-wheel drive switching type automobile, a bypass bypassing a second negative pressure delay valve is provided in a negative pressure pipe connecting the second negative pressure working chamber and the intake negative pressure system. A throttle valve opening characterized in that a conduit is provided, and a negative pressure switching valve is disposed in the bypass conduit and is closed only when traveling in four-wheel drive in response to switching from two-wheel drive to four-wheel drive. Control device.
