Abstract
PURPOSE:To simplify the configuration of an automatic transmission and suppress the cost by moving a cylinder tube upon receiving a force in a specific direction from a brake band, thereby opening a valve, and by furnishing a valve device to apply fluid pressure in the direction of decreasing the brake band fastening force or to exhaust the pressure. CONSTITUTION:When brakes are applied by supplying oil pressure to a fluid pressure cylinder 33 and fastening a brake band 22 on a brake drum 20, a cylinder tube 35 is moved together with an anchor rod as specified in the rotational direction of the brake drum 20. When the direction is such as actuating a valve device, the oil pressure wherewith the brake band 22 is fastened on the brake drum 20, is exhausted from the cylinder tube 35 to disengage brakes. When the direction of movement is opposite, the valve device shall remain out of actuation, and the brake drum fastening force is maintained to keep application of brakes continuously. That is, disengagement of brakes is carried out automatically according to the rotational direction of the brake drum 20 so as to function as a one-way clutch.
