め手段１３を介設したことを特徴とするアキシアルピス
トン機械の中立位置制御装置。In a neutral position control device for an axial piston machine, a cylinder block 3 having a plurality of pistons 4 is rotatably supported in a machine body, and the head of the piston 4 is brought into contact with a swash plate 5. is formed with a convex back portion 7 having an arcuate cross-section, and on the other hand, a concave receiving portion 8 with substantially the same cross-sectional shape as the above is formed on the casing 1 side of the machine body;
The back part 7 is slidably arranged in the receiving part 8, and the inclination angle of the swash plate 5 is made variable by sliding the back part 7. A drive shaft 9 is introduced, and the drive shaft 9 and the swash plate 5 are connected via a coupling mechanism 12 so as to be able to interlock with each other, and the axis of the drive shaft 9 is located at a position on the back portion 7 that is closer to the center of curvature of the back portion 7. The distance R2 between the axial center of the drive shaft 9 and the connecting portion in the above is made smaller than the circular arc radius R1 of the back part, and the A neutral position control device for an axial piston machine, characterized in that a positioning means 13 is provided.
