装置。In an annular hydraulic servo piston that slides in the axial direction in response to hydraulic pressure with respect to a cylinder portion arranged in the axial direction within the transmission case, the piston has a protrusion that presses a frictional engagement member on the front end surface of the piston. The recesses that house the retardation springs of the piston are arranged alternately in an annular shape,
A hydraulic x-servo piston device for an automatic transmission, characterized in that a reinforcing projection protruding toward the bottom surface of the cylinder portion is provided on the rear end surface of the piston at a position corresponding to the back surface of the recessed portion.
