Abstract
An object of the present application invention is to provide a throttle valve control device capable of effectively cooling a bearing of a throttle shaft while preventing an increase in size of a throttle body. Therefore, in a throttle valve control device in which flow pathsTtoTthrough which a heat exchange medium flows are formed in a throttle body, the diameter of a first bearingof a throttle shaftis greater than the diameter of a second bearing, the flow pathsTtoTare disposed along an outer periphery of an intake passageto overlap with the second bearingwhen viewed from a flow direction of the intake passage, and an inlet portionTand the outlet portionTof the flow pathsTtoTare disposed to sandwich the first bearing
