CONSTITUTION: A rear shaft part 4b is coaxially coupled to the rear end of a rotary shaft 4, supported to a front housing 2 and a cylinder block 1, through a coupling body 5. The rear shaft part 4b is supported internally of a sheath pipe 6a, engaged with a rear slide hole 1d of a cylinder block 1, through a bearing 25 and a sleeve 7. The front end surface of a shaft cylinder part 61 of a control piston 6b is brought into contact with the rear end surface of the sheath pipe 6a to form a power member for axially displacing the sleeve 7. A swash plate 9 is pivotally supported to the front end part of the sleeve 7 through the sleeve 7a, and a duplex piston 10 is engaged with the swash plate 9 through shoes 11 and 12. A pin 9b protruded from a bridge 9a of the swash plate 9 is engaged with a guide oblong hole 5a of the coupling body 5 through a rotor 9c.
