PROBLEM TO BE SOLVED: To improve assembly workability and shorten a vacuum hose. SOLUTION: A VSV 4 for idle up is fastened on an air cleaner 3 supported on an engine 2 through a floating mechanism 9. The VSV for idle up is supported in a floating state against the engine 2 through the air cleaner 3, and transmission of oscillation of the engine 2 to the VSV 4 for idle up is restrained. The VSV 4 for idle up is fastened on the air cleaner 3 equipped on the engine 2, and length of a vacuum hose 8 connected to the side of the VSV 4 for idle up and the engine 2 becomes short in comparison with a vacuum hose connected to an engine and a car body of conventional technology. Additionally, it becomes needless to carry out work to deliver the vacuum hose 8 from the engine 2 to a car body, and workability and productivity is improved by it. |
