ABSTRACT:
A hydraulic servo device for an automatic transmission is presented with a reduced axial length as a result of the manner in which oil pressure is fed into the cylinder. The hydraulic servo device includes a cylinder, a piston position to slide within the cylinder, a rod connected to the piston, and a cover member for closing the open end of the cylinder. The cover member, in association with the cylinder and the piston, defines an oil chamber in the cylinder. An oil passage for feeding an oil pressure to the oil chamber is formed by an opening in the cover member.
