Claims

[Claims for Utility Model Registration] (1) An air control device in which a throttle shaft with a throttle valve attached to the body of the air control device is rotatably supported by ball bearings on both sides of the throttle valve. In the support structure for a throttle valve, the inner ring of one of the two ball bearings is fixed to the throttle valve shaft, and the inner ring of the other ball bearing and the throttle valve shaft and both ball bearings are fixed to the throttle valve shaft. A small gap is provided between each outer ring of the ball bearing and the body, and both end surfaces of each outer ring of both ball bearings are secured by a locking part formed on the body and a stopper member that is also press-fitted into the body. A support structure for a throttle valve in an air control device in which each outer ring is fixed in the axial direction of the throttle valve shaft by holding the outer rings together. (2) A support structure for a throttle valve in an air control device in which a throttle shaft with a throttle valve attached to the body of the air control device is rotatably supported by ball bearings on both sides of the throttle valve. A minute gap is provided between the inner rings of both ball bearings and the throttle valve shaft, and an elastic member is installed in such a manner that it is positioned in the axial direction of the throttle valve shaft with respect to this minute gap. The inner rings of both ball bearings and the throttle valve shaft are elastically fixed by the body, and both end surfaces of each outer ring of both ball bearings are connected to locking parts formed in the body and are also press-fitted into this body. A support structure for a throttle valve in an air control device in which each outer ring is fixed in the axial direction of a throttle valve shaft by being held by a stopper member.
