  • Intake air control device
    Patent number: 10364756
    Abstract: A fixing shaft portion of a valve shaft is fixed to a throttle valve at first and second locations by first and second fixing members. A first bearing includes an inner race fixed to a first rotatable shaft portion of the valve shaft, and an outer race fixed to a valve body. A second bearing includes a slidable portion axially slidably fitted to a second rotatable shaft portion of the valve shaft and a fixing portion fixed to the valve body. A linear expansion coefficient of the throttle valve and a linear expansion coefficient of the valve body are set to be larger than a linear expansion coefficient of the valve shaft in an axial direction. A first distance measured from a center point of the throttle valve to the first location is larger than a second distance measured from the center point to the second location.
