PROBLEM TO BE SOLVED: To provide a hydraulic control device for an automatic transmission which surely restricts displacement of a plurality of hydraulic control valve relative to a housing.SOLUTION: Electromagnetic hydraulic control valves 21, 22, 23, 24, 25, 26 supplying hydraulic oil to a transmission mechanism are accommodated in a housing 11. Solenoid pins 51, 52, 53, 54, 55, 56 inserted in the housing 11 are in contact with sensor plates 41, 42, 43 mounted with hydraulic sensors 31, 32, 33, 34, 35, 36 provided in the vicinity of the electromagnetic hydraulic control valves 21, 22, 23, 24, 25, 26, and engage with the electromagnetic hydraulic control valves 21, 22, 23, 24, 25, 26. Thus, the sensor plates 41, 42, 43 prevent the solenoid pins 51, 52, 53, 54, 55, 56 from coming off, and can surely restrict displacement of the electromagnetic hydraulic control valves 21, 22, 23, 24, 25, 26 relative to the housing 11. 【課題】 ハウジングに対する複数の油圧制御弁の相対移動を確実に規制する自動変速機用油圧制御装置を提供する。【解決手段】 変速機構に作動油を供給する電磁油圧制御弁２１、２２、２３、２４、２５、２６は、ハウジング１１に収容されている。ハウジング１１に挿入されているソレノイドピン５１、５２、５３、５４、５５、５６は、電磁油圧制御弁２１、２２、２３、２４、２５、２６の近傍に設けられる油圧センサ３１、３２、３３、３４、３５、３６を搭載するセンサプレート４１、４２、４３に当接しつつ、電磁油圧制御弁２１、２２、２３、２４、２５、２６に係合している。これにより、センサプレート４１、４２、４３がソレノイドピン５１、５２、５３、５４、５５、５６の抜けを防止し、ハウジング１１に対する電磁油圧制御弁２１、２２、２３、２４、２５、２６の相対移動を確実に規制することができる。【選択図】 図２
