装置。[Scope of Claim for Utility Model Registration] In an automatic transmission equipped with an accelerator-compatible pressure regulating means that increases line pressure in accordance with an increase in accelerator opening, detecting a change from a neutral range to a forward or reverse driving range. A driving range detecting means and a delay means for delaying the increase in line pressure regulated by the accelerator compatible pressure regulating means are provided, and the delay means is set to a predetermined value from the time of switching to the driving range detected by the driving range detecting means. A hydraulic pressure control device for an automatic transmission characterized by time-operated operation.
