Abstract: A control circuit includes a computing unit, which computes a target oil pressure, a duty output unit, which outputs a drive electric current based on a result of computation of the computing unit, and a dither output unit, which applies a dither signal to a linear solenoid. The dither signal is added to the drive electric current outputted from the duty output unit and is applied to the linear solenoid.

The dither output unit reduces a pulse height of the dither signal in a dead zone in comparison to a pulse height of the dither signal in a control zone. In this way, even when an axial position of a spool is changed between the control zone and the dead zone, the amplitude of dither of the spool can be made generally constant. Thereby, it is possible to limit a change in an output oil pressure.
