The two-wheel/four-wheel drive switching device including a switching unit provided in either a power transmitting mechanism interposed between an engine and front wheels or a power transmitting mechanism interposed between the engine and rear wheels for switching between the continuation and interruption of power transmission in the power transmitting mechanism, and a control unit for controlling the switching unit. The control unit detects a drive current supplied to the switching unit and performs variable duty control to maintain the drive current at a given value. As a result, the two-wheel/four-wheel drive switching device reduces the generation of noise and greatly suppresses the consumption of power.
