。[Scope of Claim for Utility Model Registration] A casing in which a piston connected to a frictional fastening element is swingably fitted, an apply chamber to which hydraulic pressure for fastening is supplied by the piston, and an apply chamber from the apply chamber. The release chamber has a large pressure-receiving area and a release chamber to which hydraulic pressure for releasing the engagement is supplied.
In the hydraulic servo device for an automatic transmission in which the piston is biased in the direction of releasing the engagement by a return spring, the casing is provided with a communication path that communicates the release chamber with the atmosphere, and the communication path includes the A hydraulic servo device for an automatic transmission, comprising a check valve that is closed when a release chamber is applied with hydraulic pressure for releasing the engagement, and is opened when the hydraulic pressure for releasing the engagement is released.
