The first or second free piston is provided with a cylinder that slidably accommodates a second free piston, and when working pressure fluid is supplied to a pressure chamber between one end wall of the cylinder and the first or second free piston. are engaged with the intermediate collars, respectively, and the intermediate collars are brought into contact with the other free piston that is in contact with the other end wall of the cylinder, thereby holding the piston shaft in the first or second operating position. When the working pressure fluid is supplied to the intermediate pressure chamber between the first and second free pistons, the first and second free pistons abut against the cylinder end walls, respectively, causing the first and second collars to move against the pistons. A transmission actuating device characterized in that the piston shaft is held in a neutral position by being locked in the axial direction.
