する自動変速機の油圧サーボ装置。A hydraulic servo device for an automatic transmission in which a brake band is wrapped around a brake drum for changing a gear ratio of an automatic transmission, and the brake band is biased to and released from the brake drum by operating a hydraulic servo device. In the hydraulic servo device, the hydraulic servo device includes a piston that includes a piston shaft and performs the retaining biasing and releasing the retaining bias, and a cylinder that fits and inserts the piston so as to be movable in the piston axial direction between the biasing position and the releasing position. , a hydraulic chamber formed by a piston and a cylinder for moving the piston in the releasing direction, and when the piston is in the biased state, the hydraulic chamber and the outside of the cylinder communicate with each other, A hydraulic servo device for an automatic transmission, characterized in that the piston shaft is provided with an air passage that cuts off communication when the piston is in an unenergized state.
