Abstract
An intake control device includes a throttle valve and a throttle body. The throttle valve rotates to control intake air. The throttle body includes a cylindrical throttle bore portion defining a circular throttle bore that accommodates the throttle valve. The throttle body includes a cylindrical motor housing portion arranged on the radially outer side of the throttle bore portion. The motor housing portion defines a motor accommodating hole, in which a motor is accommodated to rotate the throttle valve. The throttle body includes a flange portion that extends from one axial end of the throttle bore portion to the radially outer side thereof. The throttle body is connected to the engine via the flange portion. The throttle body is formed of resin integrally with a housing connecting rib that connects the flange portion directly with the motor housing portion.
