摘要： To achieve an integration of components and the rationalization of the default opening mechanism of the throttle valve, a reduction of the load of the motor drive and a stabilization of the throttle control operation. In a default opening setting mechanism with which the default opening of the throttle valve 24 is maintained to be larger than the fully closed position when the electric current does not pass through the motor 12 driving the throttle shaft 18, the throttle lever 3 and the sleeve 45 are inserted and fixed, and the sleeve 42 united together with the return lever 2 is engaged with the sleeve 45 so as to be enabled to rotate in relative to the sleeve 45. The sleeve 42 is energized by the return coil in the close direction of the throttle valve 24 up to the initial opening position. This energized operation enables the return lever 2 to be coupled with the sleeve 3. A force for opening the valve for keeping the default opening the throttle valve 24 is energized by the spring 5 onto the throttle shaft 18 near the fully closed position.

摘要： Disclosed is a throttle device for an internal-combustion engine, in which, on one side of the side wall of a throttle body, there are formed a space for mounting a reduction gear mechanism which transmits the power from a motor to a throttle valve shaft and a default opening setting mechanism for holding a throttle valve opening at a specific opening (default opening) when the ignition switch is in off position, and a gear cover mounting frame which edges the mounting space. The frame is formed lower than the mounting level of the reduction gear mechanism. A gear cover for covering the gear mounting space is attached on the frame. A stopper for defining the default opening and a stopper for defining the full-closed position of the throttle valve are juxtaposed so as to enable position adjustments in the same direction. These stoppers serve to stop a default lever and a throttle gear, thereby enabling downsizing, weight reduction, and rationalization of fabrication and adjustments of an electronically controlled throttle device.

摘要： In a throttle body there are provided a throttle valve for controlling the flow of intake air in an internal combustion engine, and an electrically-driven actuator for actuating the throttle valve. A cover, which covers a receptacle portion, is attached to a side wall of the throttle body. The throttle assembly of the invention is provided with a potentiometer type sensor for detecting the degree of opening of the throttle valve, the sensor comprising a slider and a resistor, the slider being adapted to slide on the resistor and mounted to a peripheral surface of a driven gear so that a tip end thereof faces in a radial direction of a throttle valve shaft. The resistor is constituted by a curved resistor which confronts the slider in the said radial direction. A wall portion which holds the curved resistor is formed by molding integrally with the aforesaid cover.
