The structure (1) has an output shaft and an end plate arranged on a cylinder block unit. One end of the end plate is connected to an end of a connecting structure (2). The output shaft is arranged at an opposite side of an axial piston, where the mounting structure receives supporting forces during working operation of the axial piston. A receptacle (3) forms a bearing shell and a bearing seat for rolling or sliding a bearing or a pressure plate for a swash plate. The bearing shell or a support of the swash plate is formed with a housing of the mounting structure. An independent claim is also included for a hydromechanical function unit.
