Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent oil discharged from an accumulator from flowing back to a strainer in a hydraulic circuit in which a hydraulic pressure is temporarily held in the accumulator.SOLUTION: In an idling stop state, a solenoid valve 16 is closed to hold a hydraulic pressure of an accumulator 3. When a vehicle restarts, the solenoid valve 16 is open and a discharge pressure of the accumulator 3 acts as a D range pressure via changeover valves 17 and 19. At this time, a check valve 13 prevents the discharge pressure of the accumulator 3 from acting on a sub-strainer 12. 【課題】アキュムレータにて一時的に油圧を確保する油圧回路において、アキュムレータからの吐出油がストレーナに逆流することを防止する。【解決手段】アイドリングストップ状態では、電磁弁１６が閉塞されてアキュムレータ３の油圧が保持される。車両の再発進時、電磁弁１６が連通して、アキュムレータ３の吐出圧が、切換えバルブ１７，１９を介してＤレンジ圧として作用する。この際、アキュムレータ３の吐出圧がサブストレーナ１２に作用することを逆止弁１３により阻止する。【選択図】図１
