The control section is configured to control the secondary pressure regulating valve by a feedback control based on the target secondary pressure and the actual secondary pressure sensed by the hydraulic pressure sensor. The target secondary pressure setting section is configured to modify the target secondary pressure by adding a predetermined quantity when a correction initiation condition is satisfied, the condition initiation including a first condition that the shift operation is performed at a high speed by switching of the operation switching section.
