ABSTRACT:
An electronic throttle device includes a throttle body, a bulge, and a ring. The throttle body includes a bore part having an approximately cylindrical shape. The bore part is connected to an upstream air hose such that the upstream air hose is located on an outside of the bore part and is fastened with a fastening member from an outside of the upstream air hose. The bulge is discontinuously located along an outer circumference of the bore part and has a groove along an outer circumference of the bulge. The ring has a cross-sectional dimension larger than a depth of the groove in a radial direction of the bore part, and is located into the groove to configurate a protruding part that protrudes radially outwardly and extends entirely on the outer circumference of the bore part.
