Abstract:
1. An intake control device for an internal combustion engine, the intake control device comprising: a throttle valve that rotates to control an amount of intake air flowing into a combustion chamber of the internal combustion engine; and a throttle body that includes a throttle bore portion that is in a substantially cylindrical shape, the throttle bore portion defining a throttle bore that is in a substantially circular shape, the throttle valve being accommodated in the throttle bore, wherein the throttle body further includes a motor housing portion, which is in a substantially cylindrical shape, being arranged on an outer side of the throttle bore portion with respect to a radial direction of the throttle bore portion, the radial direction of the throttle bore portion being substantially perpendicular to an axial direction 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 further includes a flange portion that extends from a first axial end portion of the throttle bore portion to an outer side in the radial direction of the throttle bore portion, the throttle body being connected to a supporting member, which is fixed to the internal combustion 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 portions, the throttle bore portion is spaced from the motor housing portion via the flange portion, the throttle bore portion has an annular portion which has a substantially annular shape to define said throttle bore, the annular portion substantially corresponds to an outer periphery of the throttle valve when in a full-closing position, and the annular portion of the throttle bore portion is indirectly coupled to the flange portion.
