<p>PURPOSE:To prevent frictional deformation of the one end surface on the maximum inclination angle side of a guide oblong hole and the decrease of a thrust bearing life by a method wherein the one end of a guide oblong hole which is formed in a rotary shaft and with which the pin of a swash plate is engaged is formed as the minimum inclination angle guarantee part of the swash plate abutted with the pin. 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 the cylinder block 1, through a bearing 25 and a sleeve 7. A swash plate 9 is pivotally supported to the front end part of the sleeve 7 through a shaft pin 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 a coupling body 5 through a rotor 9c, one end part 5d on the rear side of the guide oblong hole 5a forms a stopper surface on the low inclination angle side abutted to the pin 9b, and is functioned as a minimum inclination angle guarantee part.</p> |
