置。[Claim for Utility Model Registration] A cylinder plate in which high-pressure ports and low-pressure ports are symmetrically bored in the circumferential direction is fixed to a substrate in which high-pressure oil passages and low-pressure oil passages are opened, and the cylinder plate is in contact with this cylinder plate. A cylinder block rotated by a drive shaft is provided, a piston is housed in a plurality of cylinders bored in the circumferential direction of the cylinder block, a swash plate is provided that contacts the head of the piston, and this swash plate is connected to the casing. In an axial piston type hydraulic transmission that is swingably supported by support shafts on both sides extending in a direction perpendicular to the drive shaft, a bearing is interposed between the support shaft of the swash plate and the casing. At the same time, move the cylinder plate in the rotational direction of the cylinder block from a position where the high pressure port and the low pressure port of the cylinder plate are arranged symmetrically with respect to the high pressure oil passage and the low pressure oil passage of the base plate, with the drive shaft as the center. An axial piston type hydraulic transmission device, characterized in that it is attached to the substrate at an inclined angle.
