Abstract
An opening end of a concave portion of a bearing holder is crimped to prevent an outer race of a ball bearing from sliding rearwardly, so that a bearing stop cover in the prior art is not needed to stop the slide-out of the outer race. Thus, the number of parts and assembling procedures for an intake air controller are reduced, thereby reducing the manufacturing const thereof. Further, since the bearing stop cover is not needed, the axial length of the bearing holder of a throttle body is shortened, thereby axially compacting the throttle body.
