Zusammenfassung:	PROBLEM TO BE SOLVED: To achieve compactification of a hydraulic control unit to improve the vehicle body mountability of an automatic transmission having the hydraulic control unit in which solenoid valves and an oil strainer are attached to a lower surface of a valve body.SOLUTION: An oil strainer 40 is disposed along a first side part 21 forming a part of a lower surface periphery of a valve body 10. Solenoid valves 52b excluding a predetermined solenoid valve 50 are arranged side by side along a second side part 22 facing the first side part 21 at the lower surface periphery of the valve body 10. The solenoid valve 50 is disposed in a space formed adjacent to the oil strainer 40 in a first side part 21 side area on a lower surface 16 of the valve body 10.SELECTED DRAWING: Figure 4 【課題】バルブボディの下面に複数のソレノイド弁とオイルストレーナとが取り付けられた油圧制御ユニットを有する自動変速機において、油圧制御ユニットのコンパクト化を図ることで、自動変速機の車体搭載性を向上させる。【解決手段】バルブボディ１０の下面周縁の一部を構成する第１辺部２１に沿うようにオイルストレーナ４０を配置し、バルブボディ１０の下面周縁において第１辺部２１に対向する第２辺部２２に沿って、所定の一部のソレノイド弁５０を除いた複数のソレノイド弁５２ｂを並べて配置して、バルブボディ１０の下面１６における第１辺部２１側の領域において、オイルストレーナ４０に隣接して生じたスペースに、一部のソレノイド弁５０を配置する。【選択図】図４
