ボ機構の構造。[Claims for Utility Model Registration] The piston is moved by supplying hydraulic pressure to the inside of the cylinder to engage the frictional engagement means, and the piston is pushed by a return spring in a direction opposite to the direction of movement by the hydraulic pressure. In an automatic transmission in which the frictional engagement means is released by using the one-way clutch, an outer race of the one-way clutch is arranged to face the piston and to be relatively fixed in the circumferential direction, and one end of the return spring A structure of a hydraulic servo mechanism for an automatic transmission, characterized in that the hydraulic servo mechanism of an automatic transmission is supported by being brought into contact with its outer race.
