Abstract

The invention provides an intake air amount control device for an engine in which the processing of a throttle body and the production of an assembly comprising an idle air control valve, an actuator and a throttle sensor can concurrently be performed to contribute to the improvement of productivity. A synthetic resin-made casing 10 is attached to a throttle body 1 as a separate body in one end side of a valve shaft 4 of a throttle valve 3. Further, the idle air control valve 25, the actuator 26 and the throttle sensor 37 are installed in the casing 10.

Description

technical field [0001] The invention relates to an improvement of an air intake control device for an engine, which has a throttle body, a bypass, an idle air control valve, an actuator, and a throttle sensor for detecting the opening of the throttle , the above-mentioned throttle body is provided with a throttle valve on the air intake passage connected with the air intake port of the engine, the above-mentioned bypass bypasses the throttle valve and is connected with the air-intake passage, and the above-mentioned idle air control valve controls the bypass when the throttle valve is fully closed. The above-mentioned actuator opens and closes to drive the above-mentioned idle air control valve. Background technique [0002] Such an engine intake air volume control device is known, for example, as disclosed in Japanese Patent Laid-Open No. 3-122246. [0003] In the past, in such an intake air volume control device for an engine, a casing was integrally formed on the throttl...
