ABSTRACT:
An intake air control device, which is mounted to a fixed member, includes a throttle body and a throttle valve. The throttle body defines an intake air passage. The throttle valve is rotatably supported in the throttle body to control an amount of intake air flowing through the intake air passage. The throttle body includes a cylindrical portion, a plurality of fixed portions, and a strain absorbing portion. The cylindrical portion defines the intake air passage that accommodates the throttle valve. The plurality of fixed portions are connected to the fixed member. The strain absorbing portion connects the cylindrical portion with the plurality of fixed portions to absorb displacement arising in the plurality of fixed portions. The strain absorbing portion is a deformable connecting arm that connects to the cylindrical portion in a location, which is apart from a radially inner periphery of the plurality of fixed portions.
